  • Picture.writeToStream() not writing out all bitmaps

    - by quickdraw mcgraw
    I'm using webview.capturePicture() to create a Picture object that contains all the drawing objects for a webpage. I can successfully render this Picture object to a bitmap using the canvas.drawPicture(picture, dst) with no problems. However when I use picture.writeToStream(fos) to serialize the picture object out to file, and then Picture.createFromStream(fis) to read the data back in and create a new picture object, the resultant bitmap when rendered as above is missing any larger images (anything over around 20KB! by observation). This occurs on all the Android OS platforms that I have tested 1.5, 1.6 and 2.1. Looking at the native code for Skia which is the underlying Android graphics library and the output file produced from the picture.writeToStream() I can see how the file format is constructed. I can see that some of the images in this Skia spool file are not being written out (the larger ones), the code that appears to be the problem is in skBitmap.cpp in the method void SkBitmap::flatten(SkFlattenableWriteBuffer& buffer) const; It writes out the bitmap fWidth, fHeight, fRowBytes, FConfig and isOpaque values but then just writes out SERIALIZE_PIXELTYPE_NONE (0). This means that the spool file does not contain any pixel information about the actual image and therefore cannot restore the picture object correctly. Effectively this renders the writeToStream and createFromStream() APIs useless as they do not reliably store and recreate the picture data. Has anybody else seen this behaviour and if so am I using the API incorrectly, can it be worked around, is there an explanation i.e. incomplete API / bug and if so are there any plans for a fix in a future release of Android? Thanks in advance.

  • Show menu when view is long pressed

    - by swift1691
    I've been looking around on the internet regarding my question but I couldn't find a straight answer. Is it possible to create a non-blocking menu similar to the overflow menu found in Android 4.0+ when a view is long pressed? I have a number of LinearLayout instances which have an OnLongClickListener which brings up a context menu, but it's not exactly what I am looking for. I was hoping for a smoother menu which is brought up when one of these instances is clicked, and removed when the user clicks outside of the menu's region. This is very similar to the way the overflow menu behaves in the Android ActionBar. So to sum up, is it possible to replicate the look-and-fell and the behavior of the overflow menu when using context menus? Here's hoping I don't have to jump through hoops to get the implementation that I desire. Thanks in advance. EDIT: After some digging I've found the PopupMenu which is exactly what I was looking for however it works only on devices running Honeycomb and above. Does anyone know of a way with which I can replicate this menu behavior in older versions of Android without using blocking windows like dialogs?

  • showDialog in Activity not displaying dialog

    - by Mohit Deshpande
    Here is my code: public class TasksList extends ListActivity { ... private static final int COLUMNS_DIALOG = 7; private static final int ORDER_DIALOG = 8; ... /** * @see android.app.Activity#onCreateDialog(int) */ @Override protected Dialog onCreateDialog(int id) { Dialog dialog; final String[] columns; Cursor c = managedQuery(Tasks.CONTENT_URI, null, null, null, null); columns = c.getColumnNames(); final String[] order = { "Ascending", "Descending" }; switch (id) { case COLUMNS_DIALOG: AlertDialog.Builder columnDialog = new AlertDialog.Builder(this); columnDialog.setSingleChoiceItems(columns, -1, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { bundle.putString("column", columns[which]); } }); dialog = columnDialog.create(); case ORDER_DIALOG: AlertDialog.Builder orderDialog = new AlertDialog.Builder(this); orderDialog.setSingleChoiceItems(order, -1, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { String orderS; if (order[which].equalsIgnoreCase("Ascending")) orderS = "ASC"; else orderS = "DESC"; bundle.putString("order", orderS); } }); dialog = orderDialog.create(); default: dialog = null; } return dialog; } /** * @see android.app.Activity#onOptionsItemSelected(android.view.MenuItem) */ @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case SORT_MENU: showDialog(COLUMNS_DIALOG); showDialog(ORDER_DIALOG); String orderBy = bundle.getString("column") + bundle.getString("order"); Cursor tasks = managedQuery(Tasks.CONTENT_URI, projection, null, null, orderBy); adapter = new TasksAdapter(this, tasks); getListView().setAdapter(adapter); break; case FILTER_MENU: break; } return false; } The showDialog doesn't display the dialog. I used the Debugger and it does executes these statements, but the dialog doesn't show. }

  • CSS - background-size: cover; not working in Firefox

    - by Jayant Bhawal
    body{ background-image: url("./content/site_data/bg.jpg"); background-size: cover; background-repeat: no-repeat; font-family: 'Lobster', cursive; } Check: http://demo.jayantbhawal.in on firefox browsers, NOT in widescreen mode. The code works on Chrome(Android + PC) and even the stock Android browser, but NOT Firefox(Android + PC). Is there any good alternative to it? Why is it not working anyways? Googled this issue a lot of times, but no one else seems to have this problem. Is it just me? In any case, how do I fix it? There are quite some questions on SO about it too, but none of them provide a legitimate solution, so can someone just tell me if they have background-size: cover; issues on firefox too? So basically tell me 3 things: 1. Why is it happening? 2. What is a good alternative to it? 3. Is this happening to you too? On Firefox browsers of course. Chrome Version 35.0.1916.114 m Firefox Version 29.0.1 Note: I may already be trying to fix it so at times you may see a totally weird page. Wait a bit and reload.

  • How can I avoid garbage collection delays in Java games? (Best Practices)

    - by Brian
    I'm performance tuning interactive games in Java for the Android platform. Once in a while there is a hiccup in drawing and interaction for garbage collection. Usually it's less than one tenth of a second, but sometimes it can be as large as 200ms on very slow devices. I am using the ddms profiler (part of the Android SDK) to search out where my memory allocations come from and excise them from my inner drawing and logic loops. The worst offender had been short loops done like, for(GameObject gob : interactiveObjects) gob.onDraw(canvas); where every single time the loop was executed there was an iterator allocated. I'm using arrays (ArrayList) for my objects now. If I ever want trees or hashes in an inner loop I know that I need to be careful or even reimplement them instead of using the Java Collections framework since I can't afford the extra garbage collection. That may come up when I'm looking at priority queues. I also have trouble where I want to display scores and progress using Canvas.drawText. This is bad, canvas.drawText("Your score is: " + Score.points, x, y, paint); because Strings, char arrays and StringBuffers will be allocated all over to make it work. If you have a few text display items and run the frame 60 times a second that begins to add up and will increase your garbage collection hiccups. I think the best choice here is to keep char[] arrays and decode your int or double manually into it and concatenate strings onto the beginning and end. I'd like to hear if there's something cleaner. I know there must be others out there dealing with this. How do you handle it and what are the pitfalls and best practices you've discovered to run interactively on Java or Android? These gc issues are enough to make me miss manual memory management, but not very much.

  • Upgraded Eclipse. Every app force closes

    - by user1309500
    I would be really grateful for some urgent advice:- I was merrily building my apps (using eclipse) for Android platform 2.2. Everything all working lovely and ready to upload to the marketplace. I thought I would try to install Google Play Licensing and in the process, I was told to download the LVL but that was not available in my SDK download list - and I read I had to updrage my SDK and ADT to the latest. So I did, I now have: ADT 17.0.0 along with ANDROID DDMS, hierarchy viewer and Traceview at 17.0.0 with Eclipse IDE 1.4.2 And I also upgraded my SDK Android 2.2 stuff to the latest. Now:- I have no errors in my app workplaces on Eclipse. But now when I run the apps, they build but force close straight away upon loading. This includes the app I was working on (and working perfectly before) and all the other apps I have ever made. Every app now force closes and I dont know what to do. Been up all night and was ready to upload them to the market place... :( Any help!? Thanks! Please!

  • Mobile development decision - Future wise (Iphone,android,symbian)

    - by Idan
    Hi, I would like to learn mobile development, but I'm not sure which category would be the most cost effective one. I know it's kind of a prophecy question, but anyhow, suggestions would be welcomed. So, as i'm pretty familiar with C++ development , I though about learning QT. I understand that using QT, I can develop once and then deploy to symbian,Mee-go, and of course to windows, linux and more. (does that mean I won't have to lean each OS internal calls, and just learn the QT library ? ) Learning development for android , mean I will have to learn Java, which is not my preferred way of action right now. Another option is to learn Objective-C, but as it only apply to Iphone development, I think it's a pretty narrow zone for me. I want to learn a library, which would be a wise decision career wise. Any recommendations ?

  • Developing Mobile App (Iphone,Blackberry,Android) for an existing website

    - by soodos
    Hey Guys I have a website and am planning to develop a mobile version of it for the iphone, blackberry and android. My website is a social network built on PHP Zend framework. Now all these mobile apps are going to be having the same functionality like the website. I am little ignorant about this - but from a high level I understand that all these mobile apps should not have to write any backend logic. For every functionality - they will simply make a web service API call to interact with the backend. So does that mean, for every functionality I need to create a web service method. Can the existing code be re used - I'm a little lost - Can someone shed some light on this matter or point me in the right direction (like some articles) Thanks

  • Hiding a value in an Android application

    - by Ewan
    Hi, I need to hide a value in a mobile (Android OS) application. As far as I can see, encrypting the value is of no use as the key to the encryption mechanism must be available to the program and is thus available to an attacker reverse-engineering the code. So, it seems that the only "solution" is to hide the secret value in the application as well as possible, obviously not ideal. Any comments? Am I missing something? If not, what's the best way to hide the value? Thanks for your ideas! Ewan

  • GData API works in Android 2.0 SDK & up?

    - by user266361
    I used GData API to pull in Calender info. It works fine if I use 1.6. But the same code, if I change to Android 2.0 & up, it would throw AuthenticationException. Below is my code for ur ref: CalendarService myService = new CalendarService("My Application"); myService.setUserCredentials(args[0],args[1]); // Set up the URL and the object that will handle the connection: URL feedUrl = new URL("http://www.google.com/calendar/feeds/"+args[0]+"/private/full"); args[0] & args[1] are the credentials. AuthenticationException will be thrown when calling myService.setUserCredentials(). Anybody has any clue?

  • CSS autohide scrollbar when not scrolling on Android webpage

    - by b0Gd4N
    Is there a way to make the scrollbar auto-hide when a user is not scrolling a webpage on an Android device, but make it visible when it is scrolling? Please note that Firefox browsers does have this behaviour enabled by default, it's just Chrome and stock(Samsung, HTC) browsers that don't. This is what I currently have: -webkit-box-flex: 1; width: 100%; overflow: auto; -webkit-overflow-scrolling: touch; And I can always see the scrollbar on the list (except in ffox)

  • How do I usb tether my Cyanogen modded G1's internet connection to my Toshiba Tecra 8000 running Xub

    - by atticus
    I have usb-tethering enabled in my phone. It works fine with Vista. When I plug my phone into my Tecra 8000 laptop running Xubuntu, dmesg shows: "usb 1-1: new full speed USB device using uhci_hcd and address 8". I see that the OS has detected it as a storage device, but I can't get it to function correctly as a network device. /dev/us* shows no usb0, but it does show /dev/usbdev1.1_ep00 /dev/usbdev1.1_ep81 /dev/usbdev1.8_ep00 ... usbdev1.8_ep83. I could just use the wireless tether app for android, but I can't get my Netgear wg511 v2 (made in China) wireless card to work in this laptop either. But that's another post for later.

    - by AJ.
    I have some e-books that I've downloaded from Project Gutenberg and some other sources to my MBP. They are all DRM free. Excluding e-mail them to my Kindle as a personal document as a method (the total size is more than 5 GB, the space provided by Amazon), is there any way to transfer these books to my Kindle App on my Nexus 7 (Android Tablet). I have the Kindle App version 3.1.7 I've already seen the question Can I sync books I didn't buy from Amazon via Kindle app? but that is not the answer I'm looking for. Thanks

  • Verizon HTC Eris - No sound on incoming phone call after 2.1 droid upgrade. Help!?

    - by Michael Rosario
    Has anyone had the following issue? I've had several issues as well: No sound when call connects, ringing or people talking. Apps would force close like weather. I did call HTC support and they had me go into Menu, Settings, Manage Applications and then clear the cache of the problem app. They also had me clear the cache once the browser was open and then do a soft reset (power off the phone and take the battery out for 15 seconds) This did fix some issues, but I am constantly turning my phone on and off to get sound back on call or to make the assigned ringtones work. There's no rhyme or reason as to why they stop working... Anyone else tried anything different??? Related problem statement... http://community.htc.com/na/htc-forums/android/f/32/p/2601/10344.aspx#10344 My wife and I are most concerned about the incoming call issue.

  • How do I sent an "over-sized" video via my Anrdoid?

    - by Wolfpack'08
    When I try to e-mail my 10-minute videos to my gmail account, but when I try to attach the videos the phone gives me this error: 'File is too large and cannot be attached'. Can't reproduce because my Android is hooked up to USB, but I'll edit-- S3x-- What's any convenient way to upload/send a video without having to get out the USB? Can I do it without using any 3rd-party apps, or at least using safe 3rd-party apps? Youtube is an option, I believe, but I want to have a hard copy on my PC for editing. Attachments are more convenient.

  • Scan And Fix a RAW drive

    - by Claus Jørgensen
    Hi Basically I got the same problem as described in this thread. When I plug my HTC Hero Android Phone with USB into my Windows 7 computer I get a "Do you want to Scan and Fix" message. However, if I click "Scan and Fix", the USB instantly unplug itself, so that's no good. I've tried updating drivers from HTC with no luck. I've also tried running chkdisk from command-line with the message that it can't be used in RAW drives. This is really really annoying, and the SD card works just fine if I ignore the message, so I just want a way to disable/hide this message permanently. If anyone have some ideas how this can be done, please let me know. Thanks.

  • Can make the proxy settings invisible when I share my internet connection via wifi?

    - by Neil
    This is probably a long shot... I have an HTC Desire and frustratingly found out after I got it that it doesn't support network proxy settings. We have a wireless network at my office that uses a proxy. My desktop at work runs ubuntu. I was wondering if the following set up would work: Plug a USB Wireless adapter into the desktop that has a working internet connection using the proxy. Setup the wireless adapter as an ad-hoc network Share the internet connection over the ad-hoc network. Make it so that the use of the proxy is invisible to users of the shared network connection. Connect the Android phone to the ad-hoc wireless network and utilise the internet connection. My question is this: Is this possible or should I give up now and not even try? I think I can handle steps 1, 2, 3 and 5. I just have no idea if step 4 even makes sense, let alone is possible. Thanks

  • Resize image on ViewSonic CD3200-EU

    - by JohnLBevan
    My ViewSonic CD3200-EU monitor doesn't seem to have an option to scale the image vertically. I've tried all the buttons which look promising and even went as far as browsing the manual (possibly my first time). http://www.viewsoniceurope.com/uk/assets/004/9269.pdf Does anyone know if this can be done? I'm connecting with an android hdmi stick (http://www.amazon.co.uk/gp/product/B008XX29WS/ref=oh_details_o00_s00_i00) so if there's any way to change screensize that way that would also be appreciated. Thanks in advance.

  • Network connection via USB

    - by Fco
    Can I get my Nexus One/Android on my local network over USB instead of WiFi and browse to my computer's IP address, the one to which the phone would be connected to, via USB? For instance, let's say my computer has an IP address 100.1.1.1 and when I go to it from the computer I would go to my localhost and see a website I've set up locally in the computer. Then, I connect my phone to that computer via USB. Can I then go to 100.1.1.1 from the browser and see the same website? All this through the USB, no WiFi?

  • How to setup Microsoft Remote Desktop?

    - by jsoldi
    I'm trying to establish a connection between this app and my Win 8.1 Pro PC, but every guide I've found so far skip steps such as what to put under PC name or under Gateway. Also, should the User name be my email or something else? I've also no idea how to find or add a user in the step 6 of this guide because the only location listed is my PC and I don't even know what am I supposed to search for. I'm not even sure whether I have to add a user or this is an step I can skip. A comprehensive guide for people without experience in networking would be highly appreciated. Both my android tablet and PC are connected to the internet through a home router, in case this matters.
