Fix android

[pthom]

With a few adpatations I could run your project under android!

I have tested it with arm and arm64, with the window and widget demos and ut runs perfectly.

Your project is seriously cool, and it is refreshing to be able to create a c++ app with 10 lines of code on a tablet.

cheers

Thank you for the cool pull request! I don't have Android devices so I tried to run it in Android emulator but I got runtime errors and no ImGui window is shown:

E eglCodecCommon: glUtilsParamSize: unknow param 0x000085b5

I don't know why this error is happening. Do you know something about this? I tried it in both Mac and Windows, with latest Android Studio.

I think it's ok to support physical devices only but it would be nice if it runs on emulators as well.

Hello,

Thank you for your answer!

I cannot currently test on an emulator (my qt creator is installed on a virtual machine, and I cannot install an emulator on a virtual machine).

I suspect this is a limitation of OpenGL in an emulator:

May be you could uncheck the setting "Use host GPU". See
