Xamarin - 警报触发但接收器未被调用

Question

所以我使用 AlarmManager 设置了一个警报，adb logcat 显示警报触发但它不会执行 Receiver 的 OnReceive 函数。

清单：

<receiver android:name=".AlarmReceiver" android:enabled="true">
    <intent-filter>
        <action android:name="com.companyname.APPNAME.SEND.REPORT"></action>
    </intent-filter>
</receiver>

创建警报：

        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);

接收者：

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 日志：

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

接收器日志从未写入我的日志文件并且未发送任何报告，这意味着接收器从未被执行。

提前致谢。

更新：这是在我将 Intent 更改为 typeof(AlarmReceiver) 之后，这就是输出

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 仍然不会执行

更新 2：

这是启动警报的当前代码

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);
    }

所以经过一些研究我意识到在 Xamarin 中你不应该从清单文件中注册你的接收器，Xamarin.Android 为此提供了一个属性。

[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.");
    }
}
