Android clipPath equivalent for hardware accelerated View

Question

The only part of my app that is still software rendered is the rendering of one view where I need to draw a round bitmap. I'm using clipPath to clip the bitmap that I need to render to the round shape.

I understand that clipPath is not hardware accelerated, but I am looking for an algorithm that would allow me to provide the equivalent functionality using hardware acceleration.

Specifically I need to create a round clipping region of a source bitmap and have that rendered to my canvas.

If you have to use clipPath you could shut down the hardware acceleration as below.

<application
    android:label="@string/application_name"
    android:hardwareAccelerated="false">

And you also could control hardware acceleration among Application, Activity, Window and View layers. Detail information describes on this Hardware Acceleration article on Android Development web site.
