Sorry for the large code. Thanks for your help. What I would like to
know is when to use weak references and if it is a good option while
using Bitmaps? If so how does it help?
/** This is the onPause function which releases the bitmap when the
imagebutton is clicked and gallery is displayed.
protected void onPause() {
super.onPause();
Log.v(TAG,"on pause called");
Log.v(TAG,"Allocated memoryin on pause before recycle done:
"+Debug.getNativeHeapAllocatedSize());
choice.setImageBitmap(null);
if(bitmap != null)
{
Log.v(TAG,"bitmap is not null");
bitmap.recycle();
if(bitmap.isRecycled())
Log.v(TAG,"bitmap is recycled");
bitmap = null;
}
if(mutBitmap != null)
{
mutBitmap.recycle();
if(mutBitmap.isRecycled())
Log.v(TAG,"mutBitmap is recycled");
mutBitmap = null;
}
Log.v(TAG,"Allocated memory on pause after recycle done: "
+Debug.getNativeHeapAllocatedSize());
}
@Override
protected void onResume() {
super.onResume();
choice.setImageBitmap(bitmap);
}
/** call to Gallery Activity **/
@Override
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
Log.v(TAG,"onActivityResult called before loading bitmap,
Allocated memory: "+Debug.getNativeHeapAllocatedSize());
if (resultCode == RESULT_OK) {
photoUri = intent.getData();
if (photoUri != null) {
try {
Log.v(TAG, "No crash 0");
bitmap =
Bitmap.createScaledBitmap(MediaStore.Images.Media.getBitmap(this.getContentResolver(),
photoUri), 300, 400, true);
Log.v(TAG, "No crash 1");
Log.v(TAG,"onActivityResult called after
loading bitmap, Allocated memory:
"+Debug.getNativeHeapAllocatedSize());
choice.setImageBitmap(bitmap);
} catch (Exception e) {
Log.v(TAG, "Unable to load image at path: " +
photoUri.getPath());
}
}
}
}
