Full Screen Theme for AppCompat

I would like to know how can I apply full screen theme ( no title bar + no actionbar ) to an activity. I am using AppCompat library from support package v7.

I've tried to applied android:theme="@android:style/Theme.NoTitleBar.Fullscreen" to my specific activity but it crashed. I think it's because my application theme is like this.

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

I also have tried this 

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

which only hides title bar but not the action bar. My current workaround is that hiding the actionbar with 

getSupportActionBar().hide();

To hide both status bar and action bar and make your activity full-screen use the following code in your activity's onResume() or onWindowFocusChanged() method:

@Override
protected void onResume() {
    super.onResume();
    View decorView = getWindow().getDecorView();
    decorView.setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
            | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_FULLSCREEN);
}

You can find more Information in the following links:

Note: Using the xml solutions provide in this thread I could only hide the status bar but not the navigation bar.

You can try the following : 

<style name="AppTheme.NoActionBar" parent="Theme.AppCompat.Light.NoActionBar">
            <item name="android:windowFullscreen">true</item>
</style>
