LAYER_TYPE_SOFTWARE not disables HW acceleration on some devices in some time

I use clipPath for clip round from canvas and then drive:

@Override
protected void onDraw(Canvas canvas) 
{   
    float radius = ((float) getWidth()) / 2;
    clipPath.reset();
    clipPath.addCircle(radius, radius, radius, Path.Direction.CW);
    canvas.clipPath(clipPath);
    super.onDraw(canvas);
}

Of couse, I set View.LAYER_TYPE_SOFTWARE for this view in constructor and in XML.

But on some devices (Android 3):

LENOVO K1
acer A501
samsung GT-P6200
ZTE V9S

throwns exception when I try to draw clipped canvas:

Interestingly, the app crashes not immediately, but after some time. For stack above start time is 2013-03-31 16:04:04, crashe time is 2013-03-31 16:18:47. Although RoundedCornerImageView is displayed at MainActivity!

I found this bug: http://code.google.com/p/android/issues/detail?id=20474

It fixed in only in 4.1 (API 16).

I decide turn on HW acceleration only for API 16 and higher

In manifest:

android:hardwareAccelerated="@bool/hw_acceleration"

In values/constants.xml:

<bool name="hw_acceleration">false</bool>

In values-16/constants.xml:

<bool name="hw_acceleration">true</bool>

I hope, this will be works!
