<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.escodro.alkaa">
<uses-permission android:name="android.permission.SCHEDULE_EXACT_ALARM" />
<application/>
</manifest>
val alarmManager: AlarmManager = getSystemService(Context.ALARM_SERVICE) as AlarmManager
val hasPermission: Boolean = alarmManager.canScheduleExactAlarms()
view raw MainActivity.kt hosted with ❤ by GitHub
val intent = Intent().apply {
action = Settings.ACTION_REQUEST_SCHEDULE_EXACT_ALARM
}
startActivity(intent)
view raw MainActivity.kt hosted with ❤ by GitHub
internal class MyBroadcastReceiver : BroadcastReceiver() {
override fun onReceive(context: Context, intent: Intent) {
when (intent.action) {
AlarmManager.ACTION_SCHEDULE_EXACT_ALARM_PERMISSION_STATE_CHANGED -> {
// reschedule all the exact alarms
}
}
}

The ACTION_SCHEDULE_EXACT_ALARM_PERMISSION_STATE_CHANGED will be sent to both runtime and manifest receivers. In our example, registering it via manifest will look like:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.escodro.alarm">
<application>
<receiver
android:name=".TaskReceiver"
android:exported="false">
<intent-filter>
<action android:name="android.app.action.SCHEDULE_EXACT_ALARM_PERMISSION_STATE_CHANGED" />
</intent-filter>
</receiver>
</application>
</manifest>
