Re: [android-developers] Re: HoneyComb isHardwareAccelerated() always returns false
Hi Dianee, isHardwareAccelerated This always returns false, as per code Canvas.java How it make decision to return false or true depending on hardware ?

Are you using the emulator or a real Xoom? I'd assume the emulator wouldn't support hardware acceleration.

If you think there is a bug, open one on http://b.android.com (but check if it hasn't been reported yet.) Put Xoom, Honeycomb and 3.0 in the title.
