Crashes on startup. Missing SCHEDULE_EXACT_ALARM or USE_EXACT_ALARM permission?

[op3]

GPSLogger was working fine until a few days ago, when it suddenly started to misbehave. The background service is no longer running, and when I try to open GPSLogger, it crashes immediately:

I am using GrapheneOS on a Pixel 8, with Android 15. I activated SFTP upload a few days ago (which was working). Not sure if that is related.

I am guessing that the problem might be this bit:

gpslogger/gpslogger/src/main/java/com/mendhak/gpslogger/GpsLoggingService.java

Lines 333 to 338 in cde1f9f

	if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
	am.setExactAndAllowWhileIdle(AlarmManager.ELAPSED_REALTIME_WAKEUP, triggerTime, sender);
	}
	else {
	am.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, triggerTime, sender);
	}

The app hasn't been allowed to use exact alarms so it's just crashing.
Can you go check in the OS settings, whether GPSLogger is allowed to work in the background. Usually that's the case where 'exact alarms' get denied. I'm not sure about Graphene but in Pixel under app settings > app batery usage > "Allow background usage".

That said, there's the proper fix for it which is to see if exact alarms are allowed, and to fall back to normal alarms. I've done it here:

gpslogger/gpslogger/src/main/java/com/mendhak/gpslogger/GpsLoggingService.java

Lines 1101 to 1110 in cde1f9f

	if(AlarmManagerCompat.canScheduleExactAlarms(nextPointAlarmManager)){
	LOG.debug("Setting exact alarm for {}s", preferenceHelper.getMinimumLoggingInterval());
	AlarmManagerCompat.setExactAndAllowWhileIdle(nextPointAlarmManager, AlarmManager.ELAPSED_REALTIME_WAKEUP,
	SystemClock.elapsedRealtime() + preferenceHelper.getMinimumLoggingInterval() * 1000L, pi);
	}
	else {
	LOG.debug("Setting inexact alarm for {}s (exact alarm disallowed/not available)", preferenceHelper.getMinimumLoggingInterval());
	AlarmManagerCompat.setAndAllowWhileIdle(nextPointAlarmManager, AlarmManager.ELAPSED_REALTIME_WAKEUP,
	SystemClock.elapsedRealtime() + preferenceHelper.getMinimumLoggingInterval() * 1000L, pi);
	}

But of course I missed it for the auto sender.

Yes it's somewhat related, if you enabled SFTP uploads then the 'auto send timer' alarm code kicked in which I missed in the Android 15 prep work.

Thank you! I had to open App settings → App battery usage: “Allow background usage” was enabled, but I had to change it from “Optimized” to “Unrestricted”. Now, GPSLogger is opening properly again.

[mendhak]

OK thanks for confirming that. I've just pushed a fix to the pull request, I'll include it in v133.

[mendhak]

v133 is now in FDroid and releases.
