Can I make the Display Object in Android by using surface object?

Question

I want to extract the specific activity's display object for making second screen that is for mirroring. But I can't find information and solve this problem. How can I do this? Could you teach me about this?

Thanks.

You can use VirtualDisplay in combination with Presentation Object. In android AOSP, in cts/tests/tests/display/.. you can find some implementation example as well.

The api for creating VirtualDisplay is:

createVirtualDisplay()

Hope this helps.
