Question

How to start an Activity on device even if screen is locked. I tried as below but it\'s not working.

Broadcast receiver:

Intent alarmIntent = new Int

You can achieve this in two ways:

1. using wake lock as explained by @Yup in this post.

2. using window flags.

Using window flags:

Open the Activity A which you want to start in onReceive(...). Paste this in onCreate() of that Activity A

final Window win= getWindow();
win.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
win.addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);

Make sure you're not pasting it before setContentView(...) :-)
