dont need creat scale bitmap, instead:

Bitmap frameBuffer = Bitmap.createBitmap(frameBufferWidth,frameBufferHeight, Config.RGB_565);

frameBufferWidth and frameBufferHeight are the sizes that you want to make your app base on those(for example 480*800)

then simply add this code:

Rect dstRect = new Rect();
canvas.getClipBounds(dstRect); // get canvas size base screen size
canvas.drawBitmap(framebuffer, null, dstRect, null);

it draw your final bitmap according to screen size
