How can I set/change the screen size on Android?

On windows I can use on the main.cpp

eglView.init("TestCPP",960,640);

But how can I set/change the solution on Android?

Why do you want to change it on Android?

I have written a windows desktop game which use a windows size of:

eglView.init("TestCPP",480,800);

When I compile it for Android part of the ‘game’ window is outside of the screen.

On a windows desktop I can change the windows size (It has a portrait format with x = 400, y = 800) .

So my leason to learn:
I cannot change the screen size on Android like on Windows Desktop.
I have to use the ‘default size’ and adapt the game screen to this one on Android?
