Android: odd issue involving hardware acceleration?
<p>My app allows the user to draw on the screen by capturing and processing touch events.  Additionally, my application makes use of Canvas.drawPicture and some other methods not supported by hardware acceleration.  </p>

<p>On some ICS devices there is an option to force hardware acceleration in settings: "force gpu rendering, use 2d harware acceleartion in applciations".  When this is enabled, my application crashes with error: <code>android.view.GLES20Canvas.drawPicture(GLES20Canvas.java:895)</code>.  So, I explicitly disabled hardware acceleration on the View that uses this method with: <code>View.setLayerType(View.LAYER_TYPE_SOFTWARE, null);</code></p>

<p>However, disabling hardware acceleration in this way impacts the performance of my drawing, the drawing gets "choppy", as if less MotionEvent.ACTION_MOVE are being generated.  This happens on all 3.0+ devices, regardless of if the "force acceleration" setting is on.  </p>

<p>So, I figure that there was something in the View's LayerType which was assisting my drawing, and that this is lost when I call <code>View.setLayerType(...)</code>.  Prior to my call to <code>View.setLayerType(...)</code>, View.getLayerType() evaluates to LAYER_TYPE_NONE.</p>

<p>Any suggestions as to how to explicitly prevent Hardware Acceleration while preserving whatever it is that was assisting my touch input?</p>
