Hoping someone can help me, as I have been stuck on this for days. I am trying to lock my device remotely when a PUSH notification arrives with a specified keyword. Else, display the message in a notification.
It correctly displays the notification but never locks the screen when the keyword is sent, nothing happens, nothing is logged. I have confirmed the string is correctly read as I previously set it to display a custom notification if the message contained the keyword. The app definitely has admin privileges and I can lock the screen using the same code inside an activity ... is there something else I need to do to get this to work in the gcmintentsevice ??
here is my gcmintentservice code
