Hi, I've got a custom View in my application which fills the entire activity.
In most cases, when I want to refresh the control I call invalidate() without any parameters. However, in certain circumstances, where I'm only changing a small area of the control, I call invalidate(Rect) to avoid redrawing the entire screen. This is important because in these situations I need the update to be as fast as possible. This seems to work fine, however, when I enable hardware acceleration in Honeycomb (i.e. set android:hardwareAccelerated="true"in AndroidManifest.xml), the partial redraw does not seem to work. This can be seen if I do Log.d("FOO", canvas.getClipBounds()) in my onDraw() method; the output simply shows that the whole control is being updated, whereas with hardware acceleration disabled, I get the correct region being output. Is there any way to make partial invalidation work when using hardware acceleraton?
