    WindowManager w = activity.getWindowManager();
    Display d = w.getDefaultDisplay();
    DisplayMetrics metrics = new DisplayMetrics();
    d.getMetrics(metrics);
    // since SDK_INT = 1;
    widthPixels = metrics.widthPixels;
    heightPixels = metrics.heightPixels;
    try {
        // used when 17 > SDK_INT >= 14; includes window decorations (statusbar bar/menu bar)
        widthPixels = (Integer) Display.class.getMethod("getRawWidth").invoke(d);
        heightPixels = (Integer) Display.class.getMethod("getRawHeight").invoke(d);
    } catch (Exception ignored) {
    }
    try {
        // used when SDK_INT >= 17; includes window decorations (statusbar bar/menu bar)
        Point realSize = new Point();
        Display.class.getMethod("getRealSize", Point.class).invoke(d, realSize);
        widthPixels = realSize.x;
        heightPixels = realSize.y;
    } catch (Exception ignored) {
    }
    

    EDIT: slightly improved version (avoid firing exceptions on non-supported OS version):

    WindowManager w = activity.getWindowManager();
    Display d = w.getDefaultDisplay();
    DisplayMetrics metrics = new DisplayMetrics();
    d.getMetrics(metrics);
    // since SDK_INT = 1;
    widthPixels = metrics.widthPixels;
    heightPixels = metrics.heightPixels;
    // includes window decorations (statusbar bar/menu bar)
    if (Build.VERSION.SDK_INT >= 14 && Build.VERSION.SDK_INT < 17)
    try {
        widthPixels = (Integer) Display.class.getMethod("getRawWidth").invoke(d);
        heightPixels = (Integer) Display.class.getMethod("getRawHeight").invoke(d);
    } catch (Exception ignored) {
    }
    // includes window decorations (statusbar bar/menu bar)
    if (Build.VERSION.SDK_INT >= 17)
    try {
        Point realSize = new Point();
        Display.class.getMethod("getRealSize", Point.class).invoke(d, realSize);
        widthPixels = realSize.x;
        heightPixels = realSize.y;
    } catch (Exception ignored) {
    }
