Android AlarmManager有时不开火

奇怪的是，我的应用程序有成千上万的用户，对他们中的大多数人来说，这是完美的。比如说，有5%的人遇到了导致提醒不能被触发的问题

我已经将日志记录放在调度机制上，包括调度的时间戳，因此我知道提醒已调度，但没有调用AlarmReceiver

为什么经理有时不开枪

提醒逻辑.java-

public class ReminderLogic {

    public static void schedule() {
        AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);

        Intent intent = new Intent(context, AlarmReceiver.class);
        PendingIntent alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0);

        int timeMillis = ... // some calculation

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) 
            alarmManager.setExact(AlarmManager.RTC_WAKEUP, timeMillis, alarmIntent);
        else 
            alarmManager.set(AlarmManager.RTC_WAKEUP, timeMillis, alarmIntent);
    }
}

AlarmReceiver.java-

public class AlarmReceiver extends WakefulBroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent service = new Intent(context, AlarmService.class);
        startWakefulService(context, service);
    }   
}

public class BootReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        ReminderLogic.schedule();
    }

}

public class PackageReplaceReceiver extends BroadcastReceiver {

    private static final String TAG = "BootReceiver";

    @Override
    public void onReceive(Context context, Intent intent) {
        ReminderLogic.schedule();
    }

}

AlarmService.java-

public class AlarmService extends IntentService {
    private final static String TAG = "AlarmService";

    public AlarmService() {
        super(TAG);
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        ReminderLogic.schedule();

        AlarmReceiver.completeWakefulIntent(intent);
    }
}

BootReceiver.java-

public class AlarmReceiver extends WakefulBroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent service = new Intent(context, AlarmService.class);
        startWakefulService(context, service);
    }   
}

public class BootReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        ReminderLogic.schedule();
    }

}

public class PackageReplaceReceiver extends BroadcastReceiver {

    private static final String TAG = "BootReceiver";

    @Override
    public void onReceive(Context context, Intent intent) {
        ReminderLogic.schedule();
    }

}

packagerplacereceiver.java-

public class AlarmReceiver extends WakefulBroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent service = new Intent(context, AlarmService.class);
        startWakefulService(context, service);
    }   
}

public class BootReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        ReminderLogic.schedule();
    }

}

public class PackageReplaceReceiver extends BroadcastReceiver {

    private static final String TAG = "BootReceiver";

    @Override
    public void onReceive(Context context, Intent intent) {
        ReminderLogic.schedule();
    }

}

AndroidManifest.xml-

    <service android:name=".reminders.AlarmService" />
    <receiver android:name=".reminders.AlarmReceiver" />

    <receiver
        android:name=".reminders.BootReceiver"
        android:exported="true" >
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
    </receiver>
    <receiver
        android:name=".reminders.PackageReplaceReceiver"
        android:exported="true" >
        <intent-filter>
            <action android:name="android.intent.action.MY_PACKAGE_REPLACED" />
        </intent-filter>
    </receiver>

这5%的用户可能有任何taskManager在警报响起之前杀死你的应用程序。例如，华为设备有自己的节能装置，应用程序必须受到保护才能不被杀死……哦，非常有趣，确实有一些用户抱怨华为。你知道如何保护一个应用程序不被杀掉吗？抱歉，没有。我也搜索过那个案例，但没有根是不可能的。唯一的方法就是告知用户。特别是对于whatsApp，我可以看到这在我的华为中是自动保护的，但我认为这是在能源管理器内部实现的。谢谢，我将尝试与我的客户核实这一点。
