Help Needed for Alarm Manager

[iraunit]

I am learning Android and trying to automatically wake up the phone if it is in sleep mode and show something like an alarm app shows from a broadcast Receiver. I am not finding this anywhere, I think you have implemented this feature, I also tried searching in the code but couldn't find it. Could you please help me?

Sorry for being so late; somehow I missed the email from GitHub. The code to set the alarm can be found in the following method:

ShakeAlarmClock/app/src/main/java/in/basulabs/shakealarmclock/Activity_AlarmsList.java

Line 505 in 3baae64

private void setAlarm(@NonNull Bundle data) {

The intent is delivered to the broadcast receiver, which then acts accordingly.

Note that you need the android.permission.SCHEDULE_EXACT_ALARM in Manifest (assuming you are targetting Android 13) to be able to schedule exact alarms. Furthermore, Android is very specific about setting exact alarms, and they can only be set by apps which require them for their core functionality.
