So I set up an Alarm using AlarmManager, adb logcat shows that the alarm triggers but it won't execute the Receiver's OnReceive function.
Manifest:
<receiver android:name=".AlarmReceiver" android:enabled="true">
<intent-filter>
<action android:name="com.companyname.APPNAME.SEND.REPORT"></action>
</intent-filter>
</receiver>
Alarm Creation:
if (Exists(context)) return;
AlarmManager alarmMgr = (AlarmManager)context.GetSystemService(Context.AlarmService);
Intent intent = new Intent("com.companyname.APPNAME.SEND_REPORT");
PendingIntent alarmIntent = PendingIntent.GetBroadcast(context, 1337, intent, PendingIntentFlags.CancelCurrent);
Calendar calendar = Calendar.Instance;
calendar.TimeInMillis = DateTimeOffset.UtcNow.ToUnixTimeMilliseconds();
alarmMgr.SetInexactRepeating(AlarmType.RtcWakeup, calendar.TimeInMillis, 1000 * 10, alarmIntent);
Receiver:
public class AlarmReceiver : BroadcastReceiver
{
public override void OnReceive(Context context, Intent intent)
{
Classes.Log.Write("Reports alarm received.");
PowerManager pm = (PowerManager)context.GetSystemService(Context.PowerService);
PowerManager.WakeLock wl = pm.NewWakeLock(WakeLockFlags.Partial, "SendReports");
wl.Acquire();
Classes.Network.SendReportsAsync();
wl.Release();
Classes.Log.Write("Reports alarm finished.");
}
}
ADB Logcat logs:
07-23 11:08:46.723 1312 1863 V AlarmManager: Triggering alarm #0: 0 when =1595491710351 package =com.companyname.APPNAME operation =*walarm*:com.companyname.APPNAME.SEND_REPORT flags =0x0
Receiver logs are never written to my log file and no reports are sent, meaning the Receiver was never executed.
Thanks in advance.
UPDATE: This is after I changed the Intent to typeof(AlarmReceiver), that's the output
07-23 17:43:20.616 1312 1863 V AlarmManager: Triggering alarm #0: 0 when =1595515400614 package =com.companyname.ReportOne operation =*walarm*:com.companyname.ReportOne/md5057b6bb0fb853ea7a7a76aecdac4ee0b.AlarmReceiver flags =0x0
AlarmReceiver still won't execute
UPDATE 2:
This is the current code for initiating the Alarm
public static void Init(Context context)
{
if (Exists(context)) return;
AlarmManager alarmMgr = (AlarmManager)context.GetSystemService(Context.AlarmService);
Intent intent = new Intent(context, typeof(AlarmReceiver));
PendingIntent alarmIntent = PendingIntent.GetBroadcast(context, 1337, intent, PendingIntentFlags.CancelCurrent);
// Set the alarm to start at 7:00 a.m.
Calendar calendar = Calendar.Instance;
calendar.TimeInMillis = DateTimeOffset.UtcNow.ToUnixTimeMilliseconds();
Classes.Log.Write(string.Format("Initializing Alarm, next alarm will fire at {0}",
DateTimeOffset.FromUnixTimeMilliseconds(GetMilliseconds()).ToString("g")));
alarmMgr.SetInexactRepeating(AlarmType.RtcWakeup, calendar.TimeInMillis, 1000 * 10, alarmIntent);
}
So after some research I realized that in Xamarin you shouldn't be registering your receivers from the manifest file, Xamarin.Android provides an Attribute for that.
[BroadcastReceiver(Enabled = true, Exported = false)]
public class AlarmReceiver : BroadcastReceiver
{
public override void OnReceive(Context context, Intent intent)
{
Classes.Log.Write("Reports alarm received.");
PowerManager pm = (PowerManager)context.GetSystemService(Context.PowerService);
PowerManager.WakeLock wl = pm.NewWakeLock(WakeLockFlags.Partial, "SendReports");
wl.Acquire();
//Classes.Network.SendReportsAsync();
wl.Release();
Classes.Log.Write("Reports alarm finished.");
}
}
