Immutable bitmap crash error

Question

java.lang.IllegalStateException: Immutable bitmap passed to Canvas constructor
at android.graphics.Canvas.(Canvas.java:127)
at app.test.canvas.StartActiv         


        

Answer 1

Unless you don't want to make your IMMUTABLE bitmap to MUTABLE bitmap, you can save memory by ALWAYS REUSING THE BITMAP

workingBitmap = workingBitmap.copy(Bitmap.Config.ARGB_8888, true);
Canvas canvas = new Canvas(workingBitmap);

However I think this may be same as making the bitmap mutable by calling

workingBitmap.isMutable = true
