How to get the Android device screen size from the adb command line?

Question

I need a way to detect device screen size and density with adb. If there is no solution, where can I get the complete list of all existing android device with their screen

Answer 1

You can get screen dimensions with this code:

public int getScreenHeight() {
    return getDisplay().getHeight();
}

private Display getDisplay() {
    return ((WindowManager) getContext().getSystemService(
            Context.WINDOW_SERVICE)).getDefaultDisplay();
}


public int getScreenWidth() {
    return getDisplay().getWidth();
}

Once you have the Display in the code above you can use DisplayMetrics to get the density. DisplayMetrics will also give you absolute display with and height.
