使用不工作的告警管理器启动服务

Question

我正在尝试在我的主要活动(Home.java)中使用警报管理器启动服务(NotificationService.java)。我在执行AlarmManager的setInexactRepeating后放了一个日志，它显示成功执行了setInexactRepeating，但服务从未启动。

下面是启动服务的代码:

 public void startService(Context context){
    AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    Intent i = new Intent(Home.this, NotificationService.class);
    int minutes = 1 ;
    PendingIntent pi = PendingIntent.getService(Home.this, 0, i, 0);
    am.cancel(pi);
        am.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
           System.currentTimeMillis(),
            minutes*60*1000, pi);   
        Log.e("Service Started","Halilujia");
}

清单中的声明如下:

     <service
      android:name=".services.NotificationService"
      android:enabled="true">
 </service>
public class NotificationService extends Service {
private WakeLock mWakeLock;
private Context activity = getApplicationContext();
@Override
public IBinder onBind(Intent intent) {
    return null;
}

private void handleIntent(Intent intent) {
    // obtain the wake lock
    PowerManager pm = (PowerManager) getSystemService(POWER_SERVICE);
    mWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "DebuggingTag");
    mWakeLock.acquire();
    // check the global background data setting
    ConnectivityManager cm = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE);
    if (!cm.getBackgroundDataSetting()) {
        stopSelf();
        return;
    }
    Log.e("Just before request","Just before Request");
            // send http request here and create notification
}

@Override
public void onStart(Intent intent, int startId) {
Log.e("Onstart Called","Onstart has been Called");
handleIntent(intent);
}

@Override
 public int onStartCommand(Intent intent, int flags, int startId) {
Log.e("Onstart Called","Onstart has been Called");
handleIntent(intent);
return START_NOT_STICKY;
 }
 public void onDestroy() {
super.onDestroy();
mWakeLock.release();
 }

}

谢谢

根据评论，这是一个新的(编辑的)回答…

你方Service的舱单声明是…

<service
    android:name=".services.NotificationService"
    android:enabled="true">
</service>

…它将NotificationService声明为包含在一个名为services的包中。例子…

主包为com.example.MyApp，服务在com.example.MyApp.services。

将服务的代码文件放在/src/services中不会改变android:name属性使用的包名/路径。

要解决这个问题，要么将声明更改为使用android:name=".NotificationService，要么创建一个单独的com.example.MyApp.services包，并将服务代码文件放在那里。
