如何在由AlarmManager计划启动的服务中检索Intent Extras?

public void onCreate() {
    super.onCreate();
    int idFunc = getApplicationContext().getSharedPreferences(SPREF_NAME,Context.MODE_PRIVATE).getInt("idFunc", 0);
    String SecKey = getApplicationContext().getSharedPreferences(SPREF_NAME,Context.MODE_PRIVATE).getString("chave", null);
    Intent intent = new Intent(getApplicationContext(), ServiceEnviaClientes.class);
    Bundle bundle = new Bundle();
    bundle.putString("SecKey", SecKey);
    bundle.putInt("idFunc", idFunc);
    intent.putExtras(bundle);
    PendingIntent pintent = PendingIntent.getService(getApplicationContext(), 0, intent, 0);
    AlarmManager alarm = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
    alarm.setRepeating(AlarmManager.RTC_WAKEUP, Calendar.getInstance().getTimeInMillis(), 10*60000, pintent);
    initImageLoader(this);
}

我尝试从AlarmManager Intent传递SharedPrefereces提供的额外内容并在服务中检索它,而不是在服务运行时访问我的SharedPreferences,我认为这需要更多内存。

 @Override
public int onStartCommand(Intent intent, int flags, int startId) {
    super.onStartCommand(intent, flags, startId);
    Toast.makeText(this,"task perform in service",Toast.LENGTH_SHORT).show();
    Bundle bundle = intent.getExtras();
    mIdFunc = bundle.getInt("idFunc");
    mSecKey = bundle.getString("SecKey");
    ThreadJSONBuild td=new ThreadJSONBuild();
    td.start();
    Log.d(TAG, "onStartCommand cycle, idFunc: "+mIdFunc+" , SecKey: "+mSecKey);
    return super.onStartCommand(intent, flags, startId);
}

但我在nullmSecKey0idFunc获得了onCreate()。我不确定它是否是最佳选择,我将我的SharedPreferences检索到服务的{{1}}方法中,但不确定。

致电时

PendingIntent pintent = PendingIntent.getService(getApplicationContext(), 0,
    intent, 0);

您可能会收回现有的PendingIntent,但其中没有您的额外内容。你应该使用

PendingIntent pintent = PendingIntent.getService(getApplicationContext(), 0,
    intent, PendingIntent.FLAG_UPDATE_CURRENT);

代替。这将确保您的额外内容放在Intent中。但请注意,附加内容将在此PendingIntent的所有用户中替换。
