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 ?

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
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:
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

Hi,
Is it possible to determine that a bitmap is compressed (programatically,
of course) as a png image with an 8 bit color palette? 4 bit?
I know there are different types of png compressions, can I decide which
type is used?
If the answer is no, can anyone recommend a method
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

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?
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.

Hi,
Is it possible to retrieve the id of a thread that called a certain
function? (assuming this function can be called from several threads)
I know that it is possible to ask a Binder object which Process had called
it, but is it also possible with threads from the same process?
Thanks

Hi,
Does anyone know if there's an easy way to tell whether a Bitmap is all
black (blank)?
Thank you
