Same results with ApiDemos!
I created a new sample project (ApiDemos) using ADT with API level 11
as the target and I tried the following:
I DO get the patterned blue background in the main screen (seems like
hardware acceleration is working).
In ApiDemos.Java:
- In the "OnCreate" I added a log print for
"getListView().isHardwareAccelerated()" and was "False"
- In BouncingBalls.Java near the end of the onCreate I added a log
print :
MyAnimationView v =new MyAnimationView(this);
container.addView(v);
Log.e("Test", "Result:" + v.isHardwareAccelerated());
It was also false
- In BouncingBalls.Java at MyAnimationView.onDraw(Canvas canvas)
Log.e("Test", "Canvas is:" + canvas.isHardwareAccelerated());
It was also false
Can someone clear this out for me ?
Is hardware acceleration off ?
Is this a bug in the isHardwareAccelerated() function or am I doing
something wrong ?

Shai Levy
