Question

我正在尝试使用主要活动（Home.java）中的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，它显示了执行setInexactRepeating的成功，但是服务从未启动过。

以下是启动服务的代码：

 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");
}

以下是清单中的声明：

     <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();
 }


}

根据评论，这是一个新的（编辑过的）答案......

Service的明确声明是......

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

...声明NotificationService包含在名为services的包中。实施例...

主程序包为com.example.MyApp，服务位于com.example.MyApp.services。

在/src/services中放置服务的代码文件并不会更改android:name属性使用的包名称/路径。

要解决此问题，请更改声明以使用android:name=".NotificationService或创建单独的com.example.MyApp.services包并将服务代码文件放在其中。

使用警报管理器无法启动服务
