Apparently, doing it in onCreate breaks app, since Activity's not yet attached to a window. If you do it like so:

public void onAttachedToWindow() {
}; works.

For developers using the new Toolbar class of the Support Library, this is how it's done:

Toolbar toolbar = (Toolbar) findViewById(;

Put this line of code in your onResume(), this should help!

new Handler().postDelayed(new Runnable() { 
   public void run() { 
}, 1000);

Two ways to do it:

Activity.getWindow().openPanel(Window.FEATURE_OPTIONS_PANEL, event);

The event argument is a KeyEvent describing the key used to open the menu, which can modify how the menu is displayed based on the type of keyboard it came from.

Or... by simulating that the user has pressed the button:

IWindowManager wManager = IWindowManager.Stub.asInterface(ServiceManager.getService("window"));
KeyEvent kd = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_SOFT_LEFT);
KeyEvent ku = new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_SOFT_LEFT);
wManager.injectKeyEvent(kd.isDown(), kd.getKeyCode(), kd.getRepeatCount(), kd.getDownTime(), kd.getEventTime(), true);

After a long research and many tries, the only way seems to be simulating a KeyEvent. This makes the options menu appear:

BaseInputConnection mInputConnection = new BaseInputConnection( findViewById(, true);
KeyEvent kd = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MENU);
KeyEvent ku = new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MENU);

For me, declaring toolbar.showOverflowMenu() in onClick is not worked. openOptionsMenu() also not worked for me. Instead of that the following way is worked for me,

new Handler().postDelayed(new Runnable() {
            public void run() {
        }, 500);

Solution 11 - Android

toolbar = (Toolbar) findViewById(;

    new Handler().postDelayed(new Runnable() {
        public void run() {
    }, 100);
