GC does NOT take care of recycling Bitmaps, so the answer is that YOU
should do that.

Hi,
We are using 640*480 resolution video frames with frame rate of 10
frames/sec. Another question related to bitmaps is do we really need
to recycle bitmaps or can we assume that the Garbage Collector would
take care of disposing bitmaps?
Thank you,

Hi,
I bet that Motorola has android 2.1 or 2.1.-update1
I'm fed up of OOM problems with these, and have not found a solution
after lot of tries, including changing several bitmaps by graphic
primitives drawn on the fly to use less memory, so I just assumed that
there is something I must live with.
On the other hand, at least in my cases and I think in most of the
cases, if you cannot load these bitmaps your application cannot work
properly, so there is no way of handling such situation that may be
better than the crash itself.
Anyway your bitmap seems to be too big. What resolution are you using?
SGSII has 800x480 pixels, that means that you need about to 1536000
bytes for storing a full screen bitmap as ARGB_, but you are
requesting more than the double, a waste of space. And if you are doing
the same with several bitmaps, it is A LOT of wasted memory.

Hi,
We have an app which renders bitmaps on imageview. On Samsung
Galaxy, it works fine. But On Motorola Droid, it runs into memory
issues and crashes every now and then with the following logcat.

My question is even though we have a try catch on Bitmap.createBitmap
it is still crashing. Why is the catch block not working? And how do
we handle the exception without crashing on Motorola Droid.
Following is my code right now:
try
{
bm = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_);
}
catch (Exception ex)
{
android.util.Log.e(Bitmap, Error);
}
Thank you,
