Add documentation to enable notch on android

[nschild]

It might be convenient to include the needed android config to enable notches here

Add these lines to MainActivity.java

import android.view.WindowManager;
import android.os.Build;
import android.os.Bundle;

...
protected void onCreate(Bundle savedInstanceState) { <-- existing

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
            WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();
            layoutParams.layoutInDisplayCutoutMode = WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES;
            getWindow().setAttributes(layoutParams);
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
        }
        
        super.onCreate(savedInstanceState); <-- existing
        ...

Edit, this code works better.

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
            Window w = getWindow();
            w.setStatusBarColor(Color.TRANSPARENT);
            w.setNavigationBarColor(Color.TRANSPARENT);
            w.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | 
View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
    }
