Hi Chris, Sorry to bother you did not know have you read my previous post to you in another thread here https://github.com/PaNaVTEC/DrawableView/issues/6. Anyway, have been getting weird errors (double paint on the canvas and crashing the app) occurring when i press the save button that runs this code drawableView.obtainBitmap(bitmap); where i want to save the drawn paint together with the background image. Rather a newbie in android please tell me how I can solve this problem? Thank You
