Describe the bug It is getting exception in Android 10, 11, 12, 13.

MY CODE:

After initiating in main function with await Alarm.init() I'm using following code to create alarms.

Future<void> createAlarm(
    int alarmId, DateTime dateTime, String title, String body) async {
  final alarmSettings = AlarmSettings(
    id: alarmId,
    dateTime: dateTime,
    assetAudioPath: 'assets/notification.mp3',
    loopAudio: false,
    vibrate: true,
    volume: 1,
    //fadeDuration: 3.0,
    notificationTitle: title,
    notificationBody: body,
    enableNotificationOnKill: false,
  );
  await Alarm.set(alarmSettings: alarmSettings);
}

In AndroidManifest.xml

<service
            android:name="com.gdelataillade.alarm.services.NotificationOnKillService" />

Also it takes extra work to switch to Gradle 8.1.2 from 7.4.2 for this alarm plugin. For anyone encounter errors, please refer this: https://stackoverflow.com/questions/76108428/how-do-i-fix-namespace-not-specified-error-in-android-studio/77738936#77738936

Facing the same issue here The exception Unable to start service com.gdelataillade.alarm.alarm.AlarmService@ebc8049 with Intent { cmp={}/com.gdelataillade.alarm.alarm.AlarmService (has extras) }: android.app.MissingForegroundServiceTypeException: Starting FGS without a type callerApp=ProcessRecord{265d1d2 10234:{}} targetSDK=34 happens exactly at the time the alarm is supposed to be thrown. I'm testing on a Android 14 with Play Store pixel 4 emulator. Did all the recommended setup, but instead of targetSdk 33, I'm using the 34 (Android 14)

Hi @aykutuludag

Thanks a lot for sharing these bugs. I will take a look at them and publish a fix as soon as possible.

Hi @aykutuludag

Thanks a lot for sharing these bugs. I will take a look at them and publish a fix as soon as possible.

No problem @gdelataillade . My app has an extensive userbase in Android 5 to 14 and same thing for iOS. I will keep sharing new errors on both iOS & Android.

Thanks for taking care of the bugs. Best wishes

Only happened once but it may triggered again.

[aykutuludag]

I'm started to getting error from iOS side too. Here is one of them:

Fatal Exception: FlutterError
PlatformException(NATIVE_ERR, [Alarm] Audio player not found for ID: 63, null, null)

Fatal Exception: FlutterError
0  ???                            0x0 IOSAlarm.setAlarm + 59 (ios_alarm.dart:59)
1  ???                            0x0 (null).createAlarm + 64 (alarm_utils.dart:64)

For now it seems more stable than Android. I will share if I get new crash reports.

Note: Background audio is enabled. Plugin installed as referred from documentation.

Note2: This error happened in my iPhone 14. You are seeing those logs. I'm getting notifications I didn't encountered any problem on that. But app sometimes crashing (Not all the time, I couldn't understand why).

Note3: Once you published the new version, I will implement it immediately and release new version to check if errors gone and reports back.

@aykutuludag

Huge thanks for reporting these bugs with all the details. There are very valuable because I only have an Android 11 device to test the plugin and every Android version works differently.

I'm currently working on fixing them. I added more version checks to handle better the different versions of Android. I'll let you know when I'll make a new release.

Hi @aykutuludag

I just released version 3.0.3 with some Android fixes. I hope it will reduce the number of issues on Android. I'll take a look at iOS issues a bit later. Thanks again for your valuable feedback.

I will release new version to my app today with Alarm v3.0.3. I will share my findings in new file. Have a nice day...

[gdelataillade]

Awesome !

Don't forget to run a few test before releasing in production your app when you upgrade alarm package version. We never know.
