Android custom view Bitmap memory leak

Question

I\'ve got a custom view in which I need to draw two bitmaps, one is a background, representing the image of a map and one is a pin which will be drawn on top/left position i

Answer 1

Something that marked me in your code is that you don't recycle all your bitmaps apparently. Here are a couple of code snippets that could help:

bmp = getBitmapFromRessourceID(R.drawable.menu);
ratio = (float)this.height/(float)bmp.getScaledHeight(canvas);
temp = Bitmap.createScaledBitmap(bmp, (int)(bmp.getWidth()*ratio), (int) (bmp.getHeight()*ratio-10), false);
bmp.recycle();
bmp = temp;

and:

Bitmap temp = BitmapFactory.decodeResource(context.getResources(), resource, opts);
Bitmap bmp = Bitmap.createBitmap(temp, 0, 0, temp.getWidth(), temp.getHeight(), flip, true);
temp.recycle();
