Background: what I'm trying to do here is create a bitmap with only one color at a set alpha channel value (making the bitmap somewhat transparent) for the entire bitmap. Unfortunately, when the new bitmap (bmp) is passed to an imageView, it's NULL (according to logcat).The following code is from my app, and the error is somewhere in here: Bitmap bmp = Bitmap.createBitmap(2048, 1536, Bitmap.Config.ARGB_8888); Canvas mcanvas = new Canvas(bmp); Paint paint = new Paint(); mcanvas.drawBitmap(bmp, 0, 0, paint); paint.setARGB(10,28,0,0); Matrix matrix = new Matrix(); matrix.setValues(new float[] { 1, 0, 0, 0, 1, 0, 0, 0, 1 }); mcanvas.drawBitmap(bmp, matrix, paint); imageView.setImageBitmap(bmp); // bmp is NULL ---> FORCE CLOSE Can anyone help me spot where I went wrong? I've been digging through Bitmap, Bitmap.Config, Paint, Canvas, imageView, example SDK code, and the book I'm working from, and am not seeing it.
why don't you just go into debug mode and see where the bmp goes null? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
