Android NDK : How to get screen resolution in native binary?

Question

I have a native binary for armeabi-v7a running on an Android phone that needs to get the current resolution of the screen.

I've tried reading the framebuffer resolution from /dev/graphics/fb0 but it gives me an incorrect value (640 X 400).

Most of the solutions discussed online involve using Java , ANativeWindow or ANativeWindow_Buffer , none of which are applicable to my scenario.

Is there a way to do this?

Answer 1

For anyone who stumbles across this, I eventually ended up processing the output of the below command.

su -c dumpsys display | grep mBaseDisplayInfo
