Question

I know there’s hardware acceleration support in android sdk 11 for Canvas. If we build against 11, but target earlier sdk versions, will we get any of that support?:

<uses-sdk
  android:minSdkVersion="4"
  android:targetSdkVersion="11" />

I watched the google io presentation on this subject, but am not really sure how our Canvas calls are being accelerated. For example, if we’re drawing a bunch of lines and circles on a Canvas, are we going to see any performance improvement?:

canvas.drawLine(..);
canvas.drawLine(..);
canvas.drawCircle(..);
canvas.drawCircle(..);
...

Thanks

Answer 1

SDK versions earlier than 11 would not have the Tegra2 chip required for hardware acceleration. The code should not crash, but it is an OS-handled function.

In other words, no.

Sorry! 🙁

Hope this helped.
