Alarm Manager cancel alarm not work correctly(After Reboot)
I cancel my alarm, it's work(notification stop to arriving), but when I reboot my phone, service restart and notification arriving instead I cancel it.
In manifest : android:name="android.intent.action.BOOT_COMPLETED",
and uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"
AlarmService
class AlarmService(private val context : Context) {
private val alarmManager: AlarmManager? =
context.getSystemService(Context.ALARM_SERVICE) as AlarmManager?

fun...
