I would like to start an activity like the one used when an alarm starts ringing and a dialog dismiss appears even when the phone is locked and i am able to click it. i have this code from this site but i don't know how to call it when i extend using broadcastreceiver. it always says "the method getWindow() is undefined type for... ". I always seemed to get this error everytime i code, what does that mean. thanks for help in advance.

public void unlockScreen() {
    Window window = getWindow();
    window.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
            + WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
            + WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
            + WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
}

解决方案

Register boradcast reciever for SCREEEN_ON intent. As screen gets on your braodcast reciever onRecieve(..) will execute, Start your actitvity with flags as you have written in your post in onRecieve method.
