A:
Bitmap immutableBmp= BitmapFactory.decodeResource(getApplicationContext().getResources(),R.drawable.sample);
mutableBitmap=immutableBmp.copy(Bitmap.Config.ARGB_8888, true);
B:
Bitmap immutableBmp= BitmapFactory.decodeFile(filePath);
mutableBitmap=immutableBmp.copy(Bitmap.Config.ARGB_8888, true);
C:
BitmapFactory.Options options = new BitmapFactory.Options();
options.inMutable=true;
myBitmap=BitmapFactory.decodeFile(filePath,options);
A works but B and C don't. I am trying to convert an immutable bitmap to mutable. It works on resource images but not file images. What's the problem?
I have found the problem! All of the 3 methods above are working, there was a problem with the resolution of my image, so I thought the code didn't work and it was not mutable but I was wrong. Here is another solution to change immutable image to mutable.
