[android-developers] AvoidXfermode is deprecated since API 16, is there a replacement?
Hi, I need to draw a bitmap on another bitmap, but I only want to draw on top of pixels that have a specific color (transparent in this case) . I understand that AvoidXfermode could do that, but it is deprecated since API 16. Is there a different method to this now ? -- -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Which is more suitable for uploading large files? a service on separate process or ...
Hi, When an application needs to upload many large files, which would be a better solution: 1) Doing this on a separate process (i.e. remote service)? 2) Using a separate thread (or AsyncTask)? Is there a clear and definite answer to this? The application, by the way, is uploading things all the time - usually very small chunks of data. Every now and then it needs to send large files, so I want to do that with a separate mechanism then the one I am using. (BTW for the small chunks I am using a single task thread which works great) -- -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Why I receive a wrong valuew from InputMethodManager.isFullScreenMode()?
InputMethodManager contains a function called isFullscreenMode() that is supposed to return a boolean that indicated whether the soft keyboard is in extract mode (full screen) or not. In my application I switch from portrait to landscape mode and bring up the keyboard: mgr.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0); The keyboard shows up in fullscreen, but imm.isFullscreenMode() returns false. How is that possible? -- -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Is there any way of knowing the screen size before rotation occurs?
Hi, I am trying to figure out the screen size I will have in portrait and in landscape at the beginning of my app. I can get the real display size using Display.getRealSize() and then calculate the navigation bar height in case there is one. However, in devices with 600dp or less the navigation bar can have different heights (depending on orientation) and may even move to the right in landscape mode. My app would needs to know these paramters when it begins (the app is connected to a cloud server that receives these dimensions when it connects - so I really need to know these before the app starts doing things). My current solution is this: id = res.getIdentifier(navigation_bar_height, dimen, android); int navigation_bar_height = res.getDimensionPixelSize(id); Although this works, it is never a good practice to use android's internal resources. Is there any other way of knowing the dimensions of the screen in a different orientation BEFORE you rotate the device? -- -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Can I decide how bitmaps are compressed via png?
Eventually I figured out the answer myself: in Android it's not possible. I had to make changes to the Android frameworks to enable this feature (skia for that matter: you may look at https://github.com/androidcompile/Android_external_skia_pngCompression), but otherwise, as a developer, there's no access to these features. Developers may only use an external library in order to save a png in a color paletted format.

[android-developers] Best bitmap compression for 2 color Bitmaps
Hi, Can anyone recommend a way to compress a 2 color Bitmap? (preferably a lossless one) I suppose I should use RGB_565 (I am currently using ARGB) , but other than that, what should give me the best compression ratio? (JPEG, PNG,...) Should I think of my own compression algorithm for this? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Best bitmap compression for 2 color Bitmaps
How can I save the bitmap programatically in a 2 color palette png? Is that possible? On Sunday, December 30, 2012 5:26:42 PM UTC+2, Nobu Games wrote: You can store your bitmap as a palette-based PNG with 2 colors. As far as I know the PNG format allows lossless run-length encoding compression. If you really want to implement your own data format then the simplest approach would be a file header with image width and height, 6 bytes for the two RGB color definitions for your two colors, followed by a sequence of pixel bytes. Each byte encodes 8 sequential pixels from your bitmap where a set bit represents one color and an unset bit the other. If you want to go fancy you could RLE-encode the sequence of pixels but then you might as well store the image as a palette-based PNG.

[android-developers] Can two applications that run in the same process have different STATIC object values?
I created two Android applications that share the same user Id (sharedUserId) as well as the same process. In the first app, on startup, I set a static int variable to 1 (it's default is 0). In the second app, I load (using reflection) the same class from the other app and read the static int variable. I read 0. Since both applications run on the same process, I would expect them to share the same static values, no? Can anyone tell me what the mechanism underneath does? (are they using, maybe, different apk/dex loaders and that causes this behavior?) -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Get the calling thread's id
If two threads can access a service (that sits in the same process they are - the service could have created these threads) and use its methods, I want the service to know who was the caller. I think that Thread.getId returns the current running thread (in this case, if the service calls this function, it will always receive its own thread Id).
