I tried to accommodate the situation by setting the layer type to View.LAYER_TYPE_SOFTWARE but it was of no help.

Hi, looks like you have enabled hardware acceleration in the manifest, in order to stop receiving this exception you need to disable it

<application android:hardwareAccelerated="true">
<!-- Or in the actviity -->
<activity android:hardwareAccelerated="false" />

I believe it can be done via software call on specific cases:

Would you be interested in a pull request addressing this? I would avoid software rendering altogether in API levels from 11 through 17.

it would be awesome if you could give PR, I would merge it :)

Just FYI, I've created #130.
