        pich = pic.getHeight();

Answer 1

It's simple, just use the following command to change it to a mutable Bitmap:

myBitmap = myBitmap.copy( Bitmap.Config.ARGB_8888 , true);

Now the Bitmap myBitmap is replaced by the same Bitmap but this time is mutable

You can also choose another way of storing Pixels (ARGB_8888 etc..): https://developer.android.com/reference/android/graphics/Bitmap.Config.html
