像whatsapp

Question

我不知道为什么这段代码不起作用，我正在尝试像whatsapp这样的后台服务，它会永远运行并检查通知。

但这不起作用，我不知道我在哪里做错了。

1. 我在android manifest
中添加了服务

<receiver android:name=".Notifications"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> <action android:name="android.intent.action.TIMEZONE_CHANGED" /> <action android:name="android.intent.action.TIME_SET" /> <action android:name="com.application.Notifications" /> </intent-filter> </receiver> <service android:name=".BackgroundWorker"></service>

1. 我创建了三个类＆＃34; BackgroundWorker扩展了IntentService＆＃34;

`public BackgroundWorker（）{         超级（＆＃34; androidservice＆＃34）;     }

@Override
protected void onHandleIntent(Intent intent) {



    Log.v("BackgroundWorker:","working" );

    //user method
    createNotification(getApplicationContext(),"BackgroundWorker");
}`

2。 class＆＃39;通知扩展了BroadcastReceiver＆＃39;

@Override
public void onReceive(final Context context, Intent intent) {

    Log.d("BroadcastReceiver","onReceive");

    Intent t = new Intent(context,BackgroundWorker.class);
    context.startService(t);

}

3。我创造了第三堂课 `long alertTime = new GregorianCalendar（）。getTimeInMillis（）+ 1 * 1000;

    Intent notifications = new Intent(this,Notifications.class);

    AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);

    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,alertTime,1*1000,PendingIntent.getBroadcast(this,
            1,
            notifications,
            PendingIntent.FLAG_UPDATE_CURRENT));

    Log.d("AlarmManager",alarmManager.toString());`

我不知道我在哪里做错了。

**虽然我已经为重复设定了1秒但仍然在5分钟的间隔内收到通知**

我已经检查了android服务，我的应用程序没有运行 请帮帮我...

在执行onHandleIntent（）中的代码后，IntentService会自行停止。您需要自己扩展正常的服务并处理线程。如果你不调用stopSelf，服务将继续运行（可能直到系统杀死它）。
