• Updating the launcher icon at run-time

  - by david

  Is it possible to update the launcher icon dynamically? Currently it seems that it can only be set statically at build time using the android:icon attribute in the AndroidManifest.xml file. For example, to display a unique icon based on the device's location? Is this something that can be achieved using aliases? If so, can an alias's launcher icon be enabled/disabled dynamically?

• Facebook: "URL could not be liked because it has been blocked" error in iOS app

  - by Andrew Madsen

  I'm working on an iOS app that allows the user to like a Facebook page within the app. I've implemented this using FacebookLikeView. During the course of testing this functionality, I've liked and unliked the same page multiple times. Unfortunately, this seems to have triggered Facebook's spam detection. Now, when trying to like a page using the like button displayed by FacebookLikeView, the following error is presented: "URL could not be liked because it has been blocked". Based on reports of the same problem found by searching the web, I've filled out this form to request that Facebook remove the block. However, I've received no response from them. I'm not sure how to proceed. Has anyone else run into this issue and successfully solved it?

• Running Endpoint locally could not provide access to API explorer when HTTP proxy is enabled

  - by harik

  I'm using Android Studio(0.5.8) on Window7 x64 for developing my Android App with Google AppEngine backend. If my machine is having direct internet access and I launch backend locally (as DevApp Server) and access my API Endpoints through webbrowser (chrome) it is all working as expected. Accessing api explorer is also working fine from webbrowser. http://localhost:8080/_ah/api/explorer But if I have configured internet through http proxy (in Android Studio and also in webbrowser) then webbrowser displays initial page of backend but can't access endpoint api explorer. And deploying appbackend in Google AppEngine also fails with errors. gradlew backend:appengineUpdate Same is working fine if direct internet access is available (not via http proxy). How can we make it work with http proxy also? Any help is appreciated, Thanks.

• Only the last run in a for loop in Javascript works

  - by Mengfei Murphy

  Here is a for loop written by Javascript. It is trying to apply queries for websql. for (var i = 0; i < 10; i++){ db.transaction(function (tx){ tx.executeSql('INSERT INTO ProjSetsT (ProjID) VALUES (?);', [i]); }); } The attempt is obvious, I tried to add values "0, 1, 2, ... 9" into column ProjID in table ProjSetsT. It does not work. I only got the last element, i.e. "9" inserted, but not the first eight numbers. Is there any syntax mistakes?

• DataSet.HasChanges is true even immediately after TableAdapter.Update is run

  - by Nathan Koop

  I've got some legacy dataset code which I'm updating. I'm attempting to determine if the dataset has changes to it so I can properly prompt for a save request. However myDataset.HasChanges() always returns true. In my save method I've edited the code to determine when the dataset get's changes and made the code like this: 1. myBindingSource.EndEdit() 2. myTableAdapter.Update(myDataSet) 3. myBindingSource.EndEdit() After line 1, - myDataSet.HasChanges = true (understandable) After line 2, - myDataSet.HasChanges = false (understandable) After line 3, - myDataSet.HasChanges = true I'm unsure of why this would occur in line 3, shouldn't this be false because I just ran the updates on the dataset?

• Windows 8 Native App in Asp.net MVC?

  - by xiao

  I was not sure if this should be here or stackoverflow. I am looking at developing some windows 8 apps. I come from a web background and was really intrigued that you make them with html and javascript. I started to think though why can't you use asp.net mvc to build a windows 8 application. My question is can you somehow use asp.net mvc to build a native windows 8 application or are you suck with javascript and html?

• Using ModalAlert from cookbook - app does not load

  - by user127091

  I'm using iphone cookbook code to prompt a user for text in a UIAlertView. The cookbook code is available at http://github.com/erica/iphone-3.0-cookbook-/tree/master/C10-Alerts/03-Soliciting%20Text/ In my AppDelegate, applicationDidFinishLaunching(), I invoke as below NSString *str = [ModalAlert ask:@"what is your name?" withTextPrompt:@"ATTUID"]; But my app does not finish loading at all. I get a black screen indefinitely. There are no messages in the console. I tried creating just a UIAlertView with UITextField in the above function and it displays properly. (commenting out her code) Commenting out "CFRunLoopRun()" also loads the app. I'm probably doing something stupid but can't seem to figure it out.

• google docs + web app

  - by King

  Hi Guys I am trying to create a web app to share docs with all editor features (just like google docs). My main requirements for this app are as follows: 1. Should have all editor features (can be done using open office api, google docs api, Microsoft office web apps api) 2. Should be shared between multiple users and can be edited by multiple users and other sync features (can be done using google docs api, Microsoft office web apps) 3. Can save the document created and edited on my own/ custom server addr. (Which api can support this??? I know open office can support this) Guys can you please suggest me one api which can be used to do all the above. Also please suggest if I am underestimating any API above regarding any functionality that i thing is not supported. Thanks King

• JQuery: Run animations on the element's contents

  - by BHare

  I have a div that has some padding, border, and style applied to it. Inside the div I have just some plain text. Something like this: <div id=test style="border: 2px solid black; background-color: blue;"> The text I would like to animate </div> Normally to animate the contents I would do something like this: $('#test > *').hide(1000); But apparently the > * only selects child elements, and not non-elements (text for example) So my current work around is: <div id=test style="border: 2px solid black; background-color: blue;"> <span>The text I would like to animate</span> </div> Making a span that is not really needed.

• Timeout with GAE Java

  - by user242153

  Hi, I am having some issues with an app I have deployed on GAE. Specifically, I am intermittently running into the DeadlineExceededException where the server is not responding within the 30 seconds required. What is odd is that the code is not overly complex, it should run in milliseconds. My guess is that the delay is in dealing with the persistence manager and accessing the datastore. 2 questions: 1) What is the best way to track where all of the CPU time on the server is being used up? Log files do not seem helpful and to make things more complicated the code runs very fast when I am running it locally 2) Any tips / best practices in dealing with the 30 second exception? What are the biggest drivers of this? Datastore? HTTP requests / responses? Thanks

• The item you tried to buy is no longer available [Environment: Sandbox]

  - by Ansari

  I am trying to put In App purchase in my application. I had setup a consumable product which was working fine in Sandbox environment. Now i just made a new product which is non-consumable with new price tier, and deleted the old one. Update my code, with the new Product ID. When request is sent, it properly shows the right Product with newly added price tier, But when you tap on Buy button it gives you the error "The item you tried to buy is no longer available [Environment: Sandbox]". Any idea ?

• Ruby: Locate class definition at run time?

  - by Thor Thurn

  I'm having an odd probably with rails right now... a class is being defined somewhere, and I can't find it. Grepping for "class ClassName" hasn't managed to locate it, but it's definitely there when I load up the rails console. It's just a vanilla class inheriting from Object with nothing else defined... quite boring. So, what I'd like is a way to figure out where this class constant was originally defined from the rails console. Something to print out the value of '__ FILE __' when this class was declared, in other words. I feel like some type of metaprogramming should make this possible.

• Appengine (python) returns empty for valid queries

  - by Grant

  I've got an app with around half a million 'records', each of which only stores three fields. I'd like to look up records by a string field with a query, but I'm running into problems. If I visit the console page, manually view a record and save it (without making changes) it shows up in a query: SELECT * FROM wordEntry WHERE wordStr = 'SomeString' If I don't do this, I get 'no results'. Does appengine need time to update? If so, how much? (I was also having trouble batch deleting and modifying data, but I was able to break the problem up into smaller chunks.)

• Run intent DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN from a service

  - by Zorb

  I have a service and I want the service promote to enable it as Device Admin, until now I launched this kind of UI interactions from the service like Intent intent2 = new Intent(); intent2.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent2.setAction(android.content.Intent.ACTION_VIEW); intent2.setDataAndType(uri, "application/vnd.android.package-archive"); context.startActivity(intent2); and it works, but with DevicePolicyManager I can't find the way: Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, mAdminName); intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION, "some text."); context.startActivity(intent); does't work: do not promote nothing but also do not crash. Without intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); It simply crash because this code is inside a tread inside a service. Ideas?

• Facebook App integration with Drupal

  - by abhishekgupta92

  I am developing a facebook App for a Drupal powered Website. Broadly, I can divide the tasks in following two categories: 1) Views from the website For this part, I just use the SQL query and execute it in my facebook App. 2) Create Cotent Initially, I tried this by taking the values in a form and then inserting those values into the drupal database myself. But the problem was that there are so many modules using that content. So, is there any other way to submit the contents from the facebook application to Drupal website? I tried using the Drupal for Facebook module, but didn't like its lack of flexibility and a lot of bugs.

• iPhone check for a constant at runtime in universal app

  - by joshue

  I'm making a universal iPad/iPhone app which can use the iPad's VGA out connector to mirror the content of the app on an external screen. However, the iPhone does not have this functionality. given the following code, [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(screenInfoNotificationReceieved:) name:UIScreenDidConnectNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(screenInfoNotificationReceieved:) name:UIScreenDidDisconnectNotification object:nil]; I get this error on the phone at launch (works fine in ipad) "dyld: Symbol not found: _UIScreenDidConnectNotification" presumably because UIScreenDidConnectNotification doesnt' exist yet in 3.13. How do I check for this at runtime?

• Does Wicket hamper SEO or search engines ability to crawl?

  - by Nick

  We're coming from GWT projects and because of problems with SEO not liking GWT for our next project we're going to move clear of GWT (mainly because seo is a high priority for this next project). In choosing a new framework, I'm looking at Wicket and liking what I've seen so far. I've only done a few tutorials, but in looking at the war layout (from these tutorials) it looks like most of the html pages are in the WEB-INF folder. It this going to cause problems for SEO and search engines crawling through the sites files? Ideally, I'd like to use Wicket with some AJAX and deploy to Google App Engine.

• Piping the output of a program to Preview.app

  - by Abhay Buch

  I'm using an application (the dot program of the graphviz library) that generates a wide variety of file formats including PostScript and PDF. It can send the result to stdout or to a file. I'm currently sending it to a file and opening it with Preview. Is there any way to pipe the output and have it be read by Preview, so that I'd don't have to generate a file and have it lying around? This is going to be used by a number of people who won't know the internal structure of the generating script and I don't want to clutter their folders or complicate their lives. More generally, is there any way to take a program that sends its output to stdout and pass that output to an program that usually takes it's input from a file, without actually creating a file?

• How to integrate monit into web app deployment process

  - by shabunc

  I have: Tomcat with webapp deployed via mvn tomcat:redeploy. Monit, pinging the host and restarting server if ping failed. The thing is there in a moment during the redeployment when ping will fail - and this is normal, actually. So, the question is - what is the best way to teach monit to consider the fact of redeployment and not to confuse it with "real" black outs. This is of course an issue of balance between elegance, ease of implementation and scalability. The most straightforward solution I can think of - is just to shutdown monit before deployment and start it up after once again. But this if far from elegance I guess.

• Want procmail to run a custom python script, everytime a new mail shows up

  - by Maddy

  I have a pretty usual requirement with procmail but I am unable to get the results somehow. I have procmailrc file with this content: :0 * ^To.*@myhost | /usr/bin/python /work/scripts/privilege_emails_forward.py Wherein my custom python script(privilege_emails_forward.py) will be scanning through the email currently received and do some operations on the mail content. But I am unable to get the script getting executed at the first shot(let alone scanning through the mail content). Is this a correct way of invoking an external program(python) as soon as new mail arrives? And how does my python program(privilege_emails_forward.py) will receive the mail as input? I mean as sys.argv or stdin????

• Combine Windows 8 app and settings search?

  - by askvictor

  While I've adapted to most things in windows 8 quite easily, I miss the 'combined' search feature of win 7 where pressing Win then typing would bring up all of the applications, settings and files (not that I ever really used the files part). Now, if I want to search settings I press win, start typing, then have to press the down arrow twice, then enter, then find the setting I want (I know I could press win-w, but that's just another thing to remember). Is there any way to bring back the 'unified search'?
