after reading all the QA i didnt get any proper solution. I have 2 problems
1. Alarm fires twice even if i register my receiver only in manifest.(not by code)
2. when i update interval time of alarm it gets fires randomly
here is my method for set alarm
public void AlarmCall(int min) {
Intent intent = new Intent(context, AlarmReceiver.class);
PendingIntent pintent = PendingIntent.getBroadcast(context,0 , intent, 0);
alarm = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
cancelAlarm(alarm,pintent);
if(Build.VERSION.SDK_INT<18) {
alarm.set(AlarmManager.RTC_WAKEUP, 1000 * 60 * min, pintent);
}
else if(Build.VERSION.SDK_INT>=19 && Build.VERSION.SDK_INT<=22)
{ alarm.setRepeating(AlarmManager.RTC_WAKEUP,System.currentTimeMillis(), 1000*60*min, pintent);
}
else if(Build.VERSION.SDK_INT>=23)
{ alarm.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP,1000*60*min,pintent);
}
}
method to cancel alarm :
public void cancelAlarm(AlarmManager alarm,PendingIntent p)
{
alarm.cancel(p);
Log.d("Alarm","Alarm Cancle");
}
in my project Application class i have to start alarm with 10 min time interval and it works fine , according to user input value i need to update time interval.
so i call this method with int min input value and cancel first alarm.
but in marshmallow it fires at every 5 seconds, and kitkat lollipop it fires randmoly.
even checked with setExact() method
I had the same issue, use setWindow solved the problem
long repeatInterval = 1000 * 60 * min;
long triggerTime = SystemClock.elapsedRealtime()
+ repeatInterval;
AlarmManager alarms = (AlarmManager) this.getSystemService(
Context.ALARM_SERVICE);
if (Build.VERSION.SDK_INT >= 19)
{
alarms.setWindow(AlarmManager.RTC_WAKEUP,
triggerTime,
repeatInterval,
pendingIntent);
}else{
alarms.setInexactRepeating(AlarmManager.RTC_WAKEUP,
triggerTime,
repeatInterval,
pendingIntent);}
