服务可以在几个小时内正常工作，而不是没有任何响应

当我在 Gmail 客户端中收到电子邮件时，我想在 GmailService 类中运行 CippaLippa() 方法。

我在 AndroidManifest 中有一个接收器和一个服务...

    <receiver
        android:name="com.myapp.receiver.GmailReceiver">
        <intent-filter>
            <action
                android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
    </receiver>

    <service
        android:name="com.myapp.service.GmailService"
        android:label="@string/app_name" />

以及这些类...

public class GmailReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(final Context context, final Intent intent) {


        final SharedPreferences preferences = context.getSharedPreferences("myapp.prefs", 0);

        context.startService(new Intent(context, GmailService.class));
    }
}


public class GmailService extends Service { .. etc...}

我的问题：在几个小时内一切正常，当我收到来自 Gmail 的通知时，CippaLippa() 方法会触发...然后，几个小时后，当我收到 Gmail 通知时，CippaLippa() 方法不再触发。

也许，有一种方法可以告诉 GmailService 类“保持活动状态”并继续监视 Gmail 事件？我认为这不是由于 Android 操作系统杀死了未使用的类，因为那是后台服务而不是 Activity。我不知道。

I want to run a method CippaLippa() in the GmailService class when I receive an email in Gmail client.

I've a receiver and a service in AndroidManifest...

    <receiver
        android:name="com.myapp.receiver.GmailReceiver">
        <intent-filter>
            <action
                android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
    </receiver>

    <service
        android:name="com.myapp.service.GmailService"
        android:label="@string/app_name" />

and these classes...

public class GmailReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(final Context context, final Intent intent) {


        final SharedPreferences preferences = context.getSharedPreferences("myapp.prefs", 0);

        context.startService(new Intent(context, GmailService.class));
    }
}


public class GmailService extends Service { .. etc...}

My question: everything works right for some hours and when I receive a notification from Gmail, the CippaLippa() method fires... then, after some hours, when I receive a gmail notification, the CippaLippa() method fires no more.

Maybe, there is a way to tell GmailService class to "stay alive" and continue monitoring Gmail events? I think this is not due to Android OS that kills unused classes, because that is a background service and not an Activity.
I've no clue.

以下代码将立即启动警报管理器（触发 PendingIntent）并每 60 秒运行一次任务。

    Intent logReader = new Intent();
    logReader.setClassName("com.foo.Test", "com.foo.Test.MyServiceClass");
    logReaderPI = PendingIntent.getService(context, 0, logReader, 0);
    long firstTime = SystemClock.elapsedRealtime();
    AlarmManager aMgr =  (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    aMgr.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, firstTime, 60 * 1000, logReaderPI);

The following code will start the alarm manager immediately (fire the PendingIntent) and run the task every 60 seconds.

    Intent logReader = new Intent();
    logReader.setClassName("com.foo.Test", "com.foo.Test.MyServiceClass");
    logReaderPI = PendingIntent.getService(context, 0, logReader, 0);
    long firstTime = SystemClock.elapsedRealtime();
    AlarmManager aMgr =  (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    aMgr.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, firstTime, 60 * 1000, logReaderPI);
