exception - Android Bitmap.createScaledBitmap throws java.lang.OutOfMemoryError mostly on Jelly Bean 4.1

Question

My app main purpose is to display images in following fashion as shown in image

private void setSelectedImage(int selectedImagePosition) 
{

    BitmapDrawable bd = (BitmapDrawable) drawables.get(selectedImagePosition);
    Bitmap b = Bitmap.createScaledBitmap(bd.getBitmap(), (int) (bd.getIntrinsicHeight() * 0.9), (int) (bd.getIntrinsicWidth() * 0.7), false);
    selectedImageView.setImageBitmap(b);
    selectedImageView.setScaleType(ScaleType.FIT_XY);

}

Detailed code can be find here

exception is thrown at following line

Bitmap b = Bitmap.createScaledBitmap(bd.getBitmap(), (int) (bd.getIntrinsicHeight() * 0.9), (int) (bd.getIntrinsicWidth() * 0.7), false);

Above function is called from onItemSelected. **The app still works well on 2.2 and 2.3, but throws exception immediately on 4.1 Above code works fine, but throws following exception. I didnot see any crashes in 2.2 and 2.3, but it immedidately crashes in 4.1 Is there any major difference of memory management in Jelly beans? **:

Answer 1

It's important to note that following code can cause Exception:

Bitmap bitmap = Bitmap.createScaledBitmap(oldBitmap, newWidth, newHeight, true); 
oldBitmap.recycle();

Proper is:

Bitmap bitmap = Bitmap.createScaledBitmap(oldBitmap, newWidth, newHeight, true); 
if (oldBitmap!= bitmap){
     oldBitmap.recycle();
}

because documentation says:

If the specified width and height are the same as the current width and height of the source btimap, the source bitmap is returned and now new bitmap is created.
