    see this answer

    if your API level > 13 try this if you are in activity

    Display display = getWindowManager().getDefaultDisplay();
    Point size = new Point();
    display.getSize(size);
    int width = size.x;
    int height = size.y;
    

    If you're not in an Activity you can get the default Display via WINDOW_SERVICE:

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

    getWidth and getHeight is for API level 13 or less

    UPDATE

    For API 17 and higher method Display.getRealSize() returns full size of screen, as mentioned in documentation:

    Gets the real size of the display without subtracting any window decor or applying any compatibility scale factors.

    The size is adjusted based on the current rotation of the display.

    The real size may be smaller than the physical size of the screen when the window manager is emulating a smaller display (using adb shell am display-size).

    You can try this:

     WindowManager wm = getWindowManager();
     Display d = wm.getDefaultDisplay();
     Point size = new Point();
     d.getSize(size);
     Log.i("LOG", "W=" + size.x + " , H=" + size.y);

    int width=Resources.getSystem().getDisplayMetrics().widthPixels;
    int height=Resources.getSystem().getDisplayMetrics().heightPixels;

    I needed to get the actual available height, and out of all the options this is the only thing that worked for me.

    Create a rectangle, and get its dimensions:

    Rect r = new Rect();
    activityRootView.getWindowVisibleDisplayFrame(r);
    int screenHeight = r.bottom - r.top;
    

    where activityRootView is the root view of your layout.

    If you need to extract the toolbar height:

    int availableScreenHeight = screenHeight - toolbar.getHeight();
    

    where toolbar is your toolbar view.

    availableScreenHeight will now be without the statusbar, without the toolbar, and without the navigation bar (if the device is using it).
