• OAuth secrets in mobile apps

  - by Felixyz

  When using the OAuth protocol, you need a secret string obtained from the service you want to delegate to. If you are doing this in a web app, you can simply store the secret in your data base or on the file system, but what is the best way to handle it in a mobile app (or a desktop app for that matter)? Storing the string in the app is obviously not good, as someone could easily find it and abuse it. Another approach would be to store it on you server, and have the app fetch it on every run, never storing it on the phone. This is almost as bad, because you have to include the URL in the app. I don't believe using https is any help. The only workable solution I can come up with is to first obtain the Access Token as normal (preferably using a web view inside the app), and then route all further communication through our server, where a script would append the secret to the request data and communicates with the provider. Then again, I'm a security noob, so I'd really like to hear some knowledgeable peoples' opinions on this. It doesn't seem to me that most apps are going to these lengths to guarantee security (for example, Facebook Connect seems to assume that you put the secret into a string right in your app). Another thing: I don't believe the secret is involved in initially requesting the Access Token, so that could be done without involving our own server. Am I correct?

  Hi, I'm currently working on wholesale online t-shirt shop. I have done this for fixed quantity and price, and its working fine. Now i need to do this for variable quantity and price. Here is the reference link, like what i have to do. Basic tables i have created are - CREATE TABLE attribute ( attribute_id int(11) NOT NULL auto_increment, name varchar(100) NOT NULL, PRIMARY KEY (attribute_id) ); CREATE TABLE attribute_value ( attribute_value_id int(11) NOT NULL auto_increment, attribute_id int(11) NOT NULL, value varchar(100) NOT NULL, PRIMARY KEY (attribute_value_id), KEY idx_attribute_value_attribute_id (attribute_id) ); CREATE TABLE product ( product_id int(11) NOT NULL auto_increment, name varchar(100) NOT NULL, description varchar(1000) NOT NULL, price decimal(10,2) NOT NULL, image varchar(150) default NULL, thumbnail varchar(150) default NULL, PRIMARY KEY (product_id), FULLTEXT KEY idx_ft_product_name_description (name,description) ); CREATE TABLE product_attribute ( product_id int(11) NOT NULL, attribute_value_id int(11) NOT NULL, PRIMARY KEY (product_id,attribute_value_id) ); I'm not getting how to store the price based on variable quantity. Please help me to create product and its related tables. my requirement is same as above reference link.

• Delegate OpenID to Google (NOT Google Apps)

  - by Rio

  OK, I searched this question on SO but no good answer. After spent some time I figured out how to do it. I'm going to answer this myself as a way to share it. Not sure if this is the correct way to use SO, but here it goes: Now it is possible delegate OpenID to your Google account (not Google Apps). No, this is not using the demo OpenID provider using App Engine. This is your REAL Google account! First you need to enable your Google Profiles. Try to view your profile and edit it, there should be an option to set your Profile URL. You have two choices there: either use your Gmail account name (without the @gmail.com part) as your profile id, or a random number assigned to you. It's up to you to decide which one to use. Either way, that id is your profile id below. Now add the following HTML code to your delegating page: <link rel="openid2.provider" href="https://www.google.com/accounts/o8/ud?source=profiles" > <link rel="openid2.local_id" href="http://www.google.com/profiles/[YOUR PROFILE ID]" > And it's done. Now try login SO with your custom url!

• Can you overlay transparent images in Blackberry Apps?

  - by Greg

  I have a very simple application that has one screen and one button. The main screen has a verticalFieldManager with a BitmapField inside it, and one button beneath the bitmap. I want to be able to overlay another image on top of this when the user clicks a button. The overlay image is a PNG with transparent background, and this is important for design, so I can't use popupscreen or a new screen because the backgrounds are always white by default, and I've heard alpha doesn't really do the trick. I guess what I'm asking is if anyone knows a simple way to... A) take a standard verticalFieldManager and overlay a PNG on top of the inner contents B) overlay a PNG over the screen, no matter the contents The basic functionality of this app was intended to be - show an image. on click, show another overlaid on top. on click again, remove the popup image. I haven't found anything that addresses something like this online, but I have read of people doing similar things that utilize popupscreen and new screens in a way I don't need to do. Hopefully this makes sense. Thanks

• Can't send an email using a google apps account with PHPMailer

  - by Chris

  I'm trying to simply send an email using my google apps account with php. I am able to send an email in a .net application using the port 587 host smtp.googlemail.com and SSL enabled. The username is my full email address. require_once('PHPMailer_v5.1\class.phpmailer.php'); try { $mail = new PHPMailer(); $mail->Mailer = 'smtp'; $mail->SMTPSecure = 'tls'; $mail->Host = $host; $mail->Port = 587; $mail->SMTPAuth = true; $mail->Username = $from; $mail->Password = $password; $mail->AddAddress($to, $to_name); $mail->From = $from; $mail->FromName = $from_name; $mail->Subject = $subject; $mail->MsgHTML($body); $mail->IsHTML(true); $mail->Send(); } catch (phpmailerException $e) { echo $e->errorMessage(); } catch (Exception $e) { echo $e->getMessage(); } Haven't been able to get this to work, but I've tried several different variations of this. $mail->SMTPSecure = 'ssl'; // Error: Could not connect to SMTP host. $mail->SMTPSecure = 'tls'; // Takes forever, then I get "this stream does not support SSL/crypto PHPMailer_v5.1\class.smtp.php" I don't care how, but I need to send an email using gmail here. It can be with this library or a different one.

• Licensing iPhone apps per user in existing system

  - by Alxandr

  I've been asked by my job to write a iPhone app for an existing system for managing worktasks. This system is proprietary and costs money, so in order to login you need to be a customer. Now, I've got two questions about the legality of licensing iPhone apps with this system: My company would like to be able to sell the app for profit, but not as a one-time payment, but as a added subscription-fee to the already existing one. Is it legal for us (according with the terms of distributing an iPhone app on the Apple App Store) to do this? That way we'll just add another field to the users-database saying weather or not iPhone is enabled for them, and distribute the app as a free app on App Store. If the previous question is not legal, we'd like to just create a free app and distribute it as part of the existing system. In other words, no extra fee for using the iPhone app for the users, but still free distribution trough App Store. Due to our company not being american or having an office in the U.S. at all enterprice account is not an option. Please let me know if there is anything wrong with any of the above approaches.

• Recommendations to handle development and deployment of php web apps using shared project code

  - by Exception e

  I am wondering what the best way (for a lone developer) is to develop a project that depends on code of other projects deploy the resulting project to the server I am planning to put my code in svn, and have shared code as a separate project. There are problems with svn:externals which I cannot fully estimate. I've read subversion:externals considered to be an anti-pattern, and How do you organize your version control repository, but there is one special thing with php-projects (and other interpreted source code): there is no final executable resulting from your libraries. External dependencies are thus always on raw source code. Ideally I really want to be able to develop simultaneously on one project and the projects it dependends on. Possible way: Check out a projects' dependency in a sub folder as a working copy of the trunk. Problems I foresee: When you want to deploy a project, you might want to freeze its dependencies, right? The dependency code should not end up as a duplicate in the projects repository, I think. *(update1: I additionally assume svn:ignore will pose problems if I cannot fall back on symlinks, see my comment) I am still looking for suggestions that do not require the use junction points. They are a sort of unsupported hack in winxp, which may break some programs* This leads me to the last part of the question (as one has influence on the other): how do you deploy apps whith such dependencies? I've looked into BuildOut for Python, but it seems to be tightly related to the python ecosystem (resolving and fetching python modules from the web etc). I am very eager to learn about your best practices.

• Using Cucumber With Modular Sinatra Apps

  - by Rob Conery

  I'm building out a medium-sized application using Sinatra and all was well when I had a single app.rb file and I followed Aslak's guidance up on Github: http://wiki.github.com/aslakhellesoy/cucumber/sinatra As the app grew a bit larger and the app.rb file started to bulge, I refactored out a lot of of the bits into "middleware" style modules using Sinatra::Base, mapping things using a rack-up file (config.ru) etc. The app works nicely - but my specs blew up as there was no more app.rb file for webrat to run against (as defined in the link above). I've tried to find examples on how to work this - and I think I'm just not used to the internal guts of Cuke just yet as I can't find a single way to have it cover all the apps. I tried just pointing to "config.ru" instead of app.rb - but that doesn't work. What I ended up doing - which is completely hackish - is to have a separate app.rb file in my support directory, which has all the requires stuff so I can at least test the model stuff. I can also specify routes in there - but that's not at all what I want to do. So - the question is: how can I get Cucumber to properly work with the modular app approach?

• Dynamic Collapsable Flow Chart Online

  - by Simon

  Been looking through a number of other related posts relating to flowchart software. I have been asked to put together a document outlining some of the typical problems our users encounter with our software product. What I would like to do, is create an interactive/online flowchart that lets users choose from 4-5 overall headings on whats wrong. Then for this to dynamically expand more choices on pinpointing the problem, and so on and so on, until they can get a resolution to their problem. The key thing that I have not been able to find in some of the flowchart software out there, is having the click + expand element. - I dont want all options to appear to the end-user in a huge flow chart as it will distract away from their specific issue. - I want them to be able to click away and go down a specific avenue that will end up giving them some good things to try, based on their decisions/clicks. I was originally thinking of perhaps putting something in Flex or Silverlight (ideally someone would have a template out there) but am now thinking of taking advantage of 3rd party (ideally free) software. This will need to be hosted in a browser. Any ideas?

• Developping an online music store

  - by Simon

  We need to develop an application to sell music online. No need to specify that all will be done quite legally and in so doing, we have to plan an interface to pay artists. However, we are confronted with a question: What is the best way to store music on the server? Should we save it on server's disk from a HTTP fileupload? Should we save via FTP or would it be wiser to save it in the database? No need to say that we need it to be the most safiest as possible. So maybe an https is required here. But, we what you think is the best way? Maybe other idea? Because in all HTTP case, upload songs (for administration) is quite long and boring, but easly linkable to a song that admin create in his web application comparativly to an FTP application to upload song on server and then list directory in admin part to link the correct uploaded song to the song informations in database. I know that its maybe not quite clear, it's because i'm french but tell me and I will try to explain part that you don't understand.

• Two part question about submitting bluetooth-enabled apps for the iPhone

  - by Kyle

  I have a couple questions about submitting blue-tooth enabled apps on the iPhone. I want to first say that bluetooth is merely an option in the application. The application does not completely rely on bluetooth as there are many modes the user can go in. First, do they require you to have the "peer-peer" key set in UIRequiredDeviceCapabilities even if bluetooth interface options can be disabled or hidden for non-bluetooth enabled devices? Basically, it's just an OPTION in the game and there are many other modes the player can play.. Does Apple not allow you to do that? I'm just curious, because it seems like something they would do. Adding to that, how do you check for it's functionality at runtime? In essence, how do you check UIRequiredDeviceCapabilities at runtime. I'm aware of checking iPhone device types, so would that be a proper way of going about it? I'm also sort of unaware which devices can run bluetooth gamekit, there doesn't seem to be a proper reference at the SDK site, or I'm unable to find it. Thanks for reading! [edit] I can confirm the existance of somebody rejected for submitting a bluetooth enabled app which didn't work on a iPhone 2G.. Of course, they didn't say if that was the MAIN function of the app, though.

• How to install previously-archived apps from xcode organizer to my iphone

  - by Ben Clayton

  Hi all. Xcode keeps an archive of all the versions of my apps that I've submitted to the app store in the 'archived applications' section. I assumed using this I could install an old version of an app to my device, in order to reproduce any problems my client may have had with that particular version. However, when I try to do this I get an error: 'this executable was signed with invalid entitlements, the entitlements specified in your applications code signing entitlements do not match those specified in your provisioning profile' The original app was signed using our App Store distribution certificate, and I use the Organizer interface to re-sign it using our Developer profile. select the archived app select the version I want to test click 'share' select 'iphone developer' next to identity save to disk (saves the ipa file) then copy the ipa to the device using the little + button you see next to 'applications' on the screen you get when you select the connected device. Then I get the error, and the app isn't installed. Is there something obvious I'm doing wrong here? Or is there a different process to re-install an archived app to my device? Thanks,

• Ember Data Sycn - LocalStorage+REST+RealTime+Online/Offline

  - by Miguel Madero

  We have a combination of requirements in terms o data access. Pre-load some reference data. We need reference data to survive browser restarts instead of just living in memory to avoid loading it all the time. I'm currently using the LocalStorageAdapter for that. Once we have it, we would like to sync changes (polling or using Socket.IO in the background and updating the LocalStorage could do the trick) There're other models that are more transactional, where we would need to directly go to the Server and get/save them. It would be nice to use something like the RESTAdapter for that. Lastly, there're some operations that should work off-line and changes should be synced later. To make it more concrete: * We pre-load vendor and "favorite products" into Local Storage. We work offline with those. * We need to sync server changes to vendor and product information. * If they search the full catalog, that requires them to be online. * When offline, we need to allow users to add something to their cart or even submit and order. We would like to queue this action and submit it when they have an Internet Connection. So a few questions are derived from this: * Is there a way to user RESTAdapter in combination with LocalStorage? * Is there some Socket.IO support? (Happy to do this part manually) * Is there Queueing support? Ideally at the Ember-Data level. I know we will have to do a lot of this manually and pull together the different lego pieces, but I wanted to ask for some perspective from experience Ember devs.

• (RoR) How to: link multiple apps, multiple URLs, one database

  - by Samson

  Hello. I am currently developing a site using Ruby on Rails. I am still a beginner who just started around a month ago. I use InstantRails on Windows 7. Here's my question. Let's say app A is functional using MYSQL database A_development. The files such as views and controller are under folder 'A'. I now know how to, say for example, link www.app.com to this app by opening port 80 and changing some lines in the mySQL config. In this app, you can register your username, login, and post some messages. I now want to create some pretty identical apps say B and C. The only thing different will be the posts that shows, and the views. You can still log in with the same username, and everything is saved in the same database. I now want the URLs to look something like A.app.com leading to app A, B.app.com leading to app B, etc. Can that be achieved? How? I've been googling for a few days already and I'm still lost. As I'm new to this forum, I'm not quite sure what info do you guys need. Please list and I'll provide them asap. Any help will be appreciated! Thanks.

• Cross Platform C library for GUI Apps?

  - by Moshe

  Free of charge, simple to learn/use, Cross Platform C library for GUI Apps? Am I looking for Qt? Bonus question: Can I develop with the said library/toolkit on Mac then recompile on PC/Linux? Super Bonus Question: Link to tutorial and/or download of said library. (RE)EDIT: The truth is that I'm in the process of catching up on the C family (coming from web development - XHTML/PHP/MySQL) to learn iPhone development. I do understand that C is not C++ or ObjectiveC but I want to keep the learning curve as simple as possible. Not to get too off topic, but I am also on the lookout for good starter books and websites. I've found this so far. I'm trying to kill many birds with one stone here. I don understand that there are platform specific extensions, but I will try to avoid those for porting purposes The idea is that I want to write the code on one machine and just compile thrice. (Mac/Win/Linux) If Objective C will compile on Windows and Linux as well as OS X then that's good. If I must use C++, that's also fine. EDIT: Link to QT Please...

• Fastest reliable way for Clojure (Java) and Ruby apps to communicate

  - by jkndrkn

  Hi There, We have cloud-hosted (RackSpace cloud) Ruby and Java apps that will interact as follows: Ruby app sends a request to Java app. Request consists of map structure containing strings, integers, other maps, and lists (analogous to JSON). Java app analyzes data and sends reply to Ruby App. We are interested in evaluating both messaging formats (JSON, Buffer Protocols, Thrift, etc.) as well as message transmission channels/techniques (sockets, message queues, RPC, REST, SOAP, etc.) Our criteria: Short round-trip time. Low round-trip-time standard deviation. (We understand that garbage collection pauses and network usage spikes can affect this value). High availability. Scalability (we may want to have multiple instances of Ruby and Java app exchanging point-to-point messages in the future). Ease of debugging and profiling. Good documentation and community support. Bonus points for Clojure support. What combination of message format and transmission method would you recommend? Why? I've gathered here some materials we have already collected for review: Comparison of various java serialization options Comparison of Thrift and Protocol Buffers (old) Comparison of various data interchange formats Comparison of Thrift and Protocol Buffers Fallacies of Protocol Buffers RPC features Discussion of RPC in the context of AMQP (Message-Queueing) Comparison of RPC and message-passing in distributed systems (pdf) Criticism of RPC from perspective of message-passing fan Overview of Avro from Ruby programmer perspective

• Packaging Java apps for the Windows/Linux desktop.

  - by alexmcchessers

  I am writing an application in Java for the desktop using the Eclipse SWT library for GUI rendering. I think SWT helps Java get over the biggest hurdle for acceptance on the desktop: namely providing a Java application with a consistent, responsive interface that looks like that belonging to any other app on your desktop. However, I feel that packaging an application is still an issue. OS X natively provides an easy mechanism for wrapping Java apps in native application bundles, but producing an app for Windows/Linux that doesn't require the user to run an ugly batch file or click on a .jar is still a hassle. Possibly that's not such an issue on Linux, where the user is likely to be a little more tech-savvy, but on Windows I'd like to have a regular .exe for him/her to run. Has anyone had any experience with any of the .exe generation tools for Java that are out there? I've tried JSmooth but had various issues with it. Is there a better solution before I crack out Visual Studio and roll my own? Edit: I should perhaps mention that I am unable to spend a lot of money on a commercial solution.

• PHP | Online Notepad

  - by user2947423

  I recently made a Chat application in Visual Basic using PHP. I used this code: <?php $msg = $_GET['w']; $logfile= 'Chats.php'; $fp = fopen($logfile, "a"); fwrite($fp, $msg); fclose($fp); ?> I'm now trying to make a Online Notepad. What i want to do is in Visual Basic create a unique ID. That unique ID, has to be his filename. I'm not very good with PHP so what i want to know is: I want the unique ID to be the filename of the "Note". Like: $logfile= '{uniqueID.php}'; Whenever the user opens the program, it'll open his uniqueID.php file and he can edit that in my program. Long Story Short (TL;DR) Program generates uniqueID uniqueID is going to be a new file; {uniqueID}.php On next open it will check if {uniqueID}.php of him/her exists else it will make a new one. I know this isn't really secure but it's to learn something for myself.

• Hey, Google: It’s Time to Add Multi-Window Multitasking To Android

  - by Chris Hoffman

  In 2012, Google’s Dianne Hackborn threatened to revoke CyanogenMod’s access to the Android Market if they moved forward with adding “Cornerstone” multitasking to their custom ROM. Samsung has since created their own multi-window multitasking feature. Dianne Hackborn said this “is something that needs to be done at the mainline platform level” so apps wouldn’t break. She was right — Android needs this as a standard feature and it’s time for Google to provide it. Doesn’t Android Have Multitasking? Android originally stood out from Apple’s iOS with its powerful multitasking. Applications can continue running in the background while you’re using another application. This makes Android powerful — you can even have BitTorrent clients downloading files in the background while using another app. Android still kept the design of a single app on screen at a time. This made a lot of sense when Android only ran on smartphones with small screens. Today, Android runs on everything from smaller smartphones all the way up to huge “phablets” like the Galaxy Note. Android has gone beyond phones and runs on 12-inch tablets, convertibles with keyboard docks, laptops, and even Android desktops. Android isn’t just a phone operating system. Samsung’s Multi-Window Isn’t Good Enough Samsung has tried to add value to Android by adding a multi-window feature. When you’re using a high-end phone like the Galaxy Note or Galaxy S, or a Galaxy tablet, you have the ability to run certain apps side-by-side with each other. There are big problems here. This only works on Samsung devices, and only on specific Samsung devices. To add support for this feature in a way that doesn’t break other apps, Samsung’s multi-window feature also only works with specific apps. You can’t just run any app in multi-window view, only the apps on the Multi Window bar Samsung provides. This prevents third-party apps from breaking, which is what Google was worried about with CyanogenMod’s Cornerstone feature. A feature that only works with a handful of apps on specific devices from a single manufacturer isn’t good enough. This feature needs to work on every Android device — or at least ones with suitably large screens and powerful enough internals. It needs to be an Android platform feature so application developers can ensure their apps will work properly with it on every device. Android developers shouldn’t have to add support for each manufacturer’s own multi-window feature if other manufacturers decide to copy Samsung. Floating Apps Are a Dirty Hack Floating apps also enable real multitasking. Remember that Android allows apps to run in the background while you’re using an app in the foreground. These apps can present interfaces that appear floating above the current app — think of it like using “always on top” to make a window always appear over every other app on a desktop operating system. You can install floating apps to browse the web, take notes, chat, and watch videos while using any app. Only apps specifically designed to run as floating apps will work, so you have to seek them out. Floating apps are also awkward to use because they float over the app you’re using, blocking parts of its interface. Microsoft added floating-window support to Skype for Android. You can have a video conversation and the other person’s face will always appear on your screen, even when you leave the Skype app. Microsoft is using more of Android’s multi-window multitasking power than Google is. Custom ROMs and Root-Only Tweaks Aren’t Acceptable Some custom ROMs are adding this feature to Android. Google threatened to revoke CyanogenMod’s access to the Android Market (now known as Google Play) if they added this feature because it could potentially break third-party apps. Today, other custom ROMs are working on split-screen multitasking. Samsung added their own version to their own devices. You can also get this feature by using a root-only Xposed Framework tweak known as XMultiWindow. If you have root access, you can get multi-window multitasking or any app on your device. This shouldn’t require rooting your device or installing a custom ROM. These third-party solutions often have awkward interfaces and bugs. We need an integrated, supported solution that works the same on every device. Why Multi-Window is Important Microsoft’s Windows 8.1 stands out among tablet operating systems for its powerful multitasking support, allowing you to view several apps side-by-side at the same time. Apple is also reported to be working on adding side-by-side apps to the iPad with iOS 8. On every competitor’s operating system, you’ll be able to view a web page while you write an email, watch a video while you browse the web, or chat with someone while you do anything else. But Android’s still remained frozen in time. Despite all Android’s underlying power — and despite the way Android allows apps to adapt to different screen sizes — Google is resisting adding this feature. Large-screen Android tablets like the Nexus 10 (remember that tablet Google hasn’t updated in over 18 months?) need this feature. So do huge phones, convertibles, laptops, and Android desktops. If tablets are the future of personal computing, we should be able to do more than one thing at a time on our tablets’ big screens. Microsoft, Samsung, and even Apple are realizing this — now it’s Google’s turn. Image Credit: Sergey Galyonkin on Flickr, Karlis Dambrans on Flickr

Here's what I've got so far: <!DOCTYPE HTML> <html manifest="cache-manifest"> <head> <script> var db = openDatabase("notes", "", "The Example Notes App!", 1048576); function renderNote(row) { // renders the note somewhere } function reportError(source, message) { // report error } function renderNotes() { db.transaction(function(tx) { tx.executeSql('CREATE TABLE IF NOT EXISTS Notes(title TEXT, body TEXT)', []); tx.executeSql(‘SELECT * FROM Notes’, [], function(tx, rs) { for(var i = 0; i < rs.rows.length; i++) { renderNote(rs.rows[i]); } }); }); } function insertNote(title, text) { db.transaction(function(tx) { tx.executeSql('INSERT INTO Notes VALUES(?, ?)', [ title, text ], function(tx, rs) { // … }, function(tx, error) { reportError('sql', error.message); }); }); } </script> <style> label { display:block; } </style> </head> <body> <form> <label for="mytitle">Title:</label> <input name="mytitle"> <label for="mytext">Text:</label> <textarea name="mytext"></textarea> <!-- There is no submit button because I want to save the info on every keystroke --> </form> </body> </html> I also know that I have to incorporate this in there somewhere: if (navigator.onLine) { // Send data using XMLHttpRequest } else { // Queue data locally to send later } But I'm not sure what even I would tie that too.

• Android - dialer icon gets placed in recently used apps after finish()

  - by Donal Rafferty

  In my application I detect the out going call when a call is dialled from the dialer or contacts. This works fine and I then pop up a dialog saying I have detected the call and then the user presses a button to close the dialog which calls finish() on that activity. It all works fine except that when I then hold the home key to bring up the recently used apps the dialer icon is there. And when it is clicked the dialog is brought back into focus in the foreground when the dialog activity should be dead and gone and not be able to be brought back to the foreground. Here is a picture of what I mean. So two questions arise, why would the dialer icon be getting placed there and why would it be recalling my activity to the foreground? Here is the code for that Activity which has a dialog theme: public class CallDialogActivity extends Activity{ boolean isRecording; AudioManager audio_service; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.dialog); audio_service = (AudioManager) getSystemService(Context.AUDIO_SERVICE); getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND); Bundle b = this.getIntent().getExtras(); String number = b.getString("com.networks.NUMBER"); String name = b.getString("com.networks.NAME"); TextView tv = (TextView) findViewById(R.id.voip) ; tv.setText(name); Intent service = new Intent(CallAudio.CICERO_CALL_SERVICE); startService(service); final Button stop_Call_Button = (Button) findViewById(R.id.widget35); this.setVolumeControlStream(AudioManager.STREAM_VOICE_CALL); stop_Call_Button.setOnClickListener(new View.OnClickListener(){ public void onClick(View v){ Intent service = new Intent(CallAudio._CALL_SERVICE); //this is for Android 1.5 (sets speaker going for a few seconds before shutting down) stopService(service); Intent setIntent = new Intent(Intent.ACTION_MAIN); setIntent.addCategory(Intent.CATEGORY_HOME); setIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(setIntent); finish(); isRecording = false; } }); final Button speaker_Button = (Button) findViewById(R.id.widget36); speaker_Button.setOnClickListener(new View.OnClickListener(){ public void onClick(View v){ if(true){ audio_service.setSpeakerphoneOn(false); } else{ audio_service.setSpeakerphoneOn(true); } } }); } @Override protected void onResume() { super.onResume(); } @Override protected void onPause() { super.onPause(); } public void onCofigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); } } It calls a service that uses AudioRecord to record from the Mic and AudioTrack to play it out the earpiece, nothing in the service to do with the dialler. Has anyone any idea why this might be happening?

• Making it GREAT! Oracle Partners Building Apps Workshop with UX and ADF in UK

  - by ultan o'broin

  Yes, making is what it's all about. This time, Oracle Partners in the UK were making great looking usable apps with the Oracle Applications Development Framework (ADF) and user experience (UX) toolkit. And what an energy-packed and productive event at the Oracle UK, Thames Valley Park, location it was. Partners learned the fundamentals of enterprise applications UX, why it's important, all about visual design, how to wireframe designs, and then how to build their already-proven designs in ADF. There was a whole day on mobile apps, learning about mobile design principles, free mobile UX and ADF resources from Oracle, and then trying it out. The workshop wrapped up with the latest Release 7 simplified UIs, Mobilytics, and other innovations from Oracle, and a live demo of a very neat ADF Mobile Android app built by an Oracle contractor. And, what a fun two days both Grant Ronald of ADF and myself had in running the workshop with such a great audience, too! I particularly enjoyed the wireframing and visual design sessions interaction; and seeing some outstanding work done by partners. Of note from the UK workshop were innovative design features not seen before and made me all the happier that developers were bringing their own ideas from the consumer IT world of mobility, simplicity, and social to the world of work apps in a smart way within an enterprise methodology too.  Partner wireframe exercise. Applying mobile design principles and UX design patterns means you've already productively making great usable apps! Next, over to Oracle ADF Mobile with it! One simple example from the design of a mobile field service app was that participants immediately saw how the UX and device functionality of the super UK-based app Hailo app could influence their designs (the London cabbie influence maybe?), as well as how we all use maps, cameras, barcode scanners and microphones on our phones could be used in work. And, of course, ADF Mobile has the device integration solutions there too! I wonder will U.S. workshops in Silicon Valley see an Uber UX influence (LOL)! That we also had partners experienced with Oracle Forms who could now offer a roadmap from Forms to Simplified UI and Mobile using ADF, and do it through through the cloud, really made this particular workshop go "ZING!" for me. Many thanks to the Oracle PartnerNetwork (OPN) team for organizing this event with us, and to the representatives of the Oracle Partners that showed and participated so well. That's what I love out this outreach. It's a two-way, solid value-add for all. Interested? Why would partners and developers with ADF skills sign up for this workshop? Here's why: Learn to use the Oracle Applications User Experience design patterns as the usability building blocks for applications development in Oracle Application Development Framework. The workshop enables attendees to build modern and visually compelling desktop and mobile applications that look and behave like Oracle Cloud Applications, and that can co-exist with partner integrations, new, or existing applications deployments. Partners learn to offer customers and clients more than just coded functionality; instead they can provide a complete user experience with a roadmap for continued ROI from applications that also creating more business and attracts the kudos and respect from other makers of apps as they're wowed by the results. So, if you're a partner and interested in attending one of these workshops and benefitting from such learning, as well as having a platform to show off some of your own work, stay well tuned to your OPN channels, to this blog, to the VoX blog, and to the @usableapps Twitter account too. Can't wait?
