Answer 1

You are right, It is showing you the resolution of your app screen and hence you getting the difference.Instead of getMetrics(), use getRealMetrics(). You can use the following code to get the actual screen size of device.

    WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
    Display display = wm.getDefaultDisplay();

    DisplayMetrics metrics = new DisplayMetrics();
    display.getRealMetrics(metrics);
    int width = metrics.widthPixels;
    int height = metrics.heightPixels;

    return width + "*" + height;
