当手机关闭并重新启动时。我想在我的共享偏好中存储一些数据。我想在我的服务 onDestroy 上执行此操作。但是当我重新启动手机或将其关闭并再次打开时，它似乎没有存储。这是我的做法。同样，这是一项服务。

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    preferences = getSharedPreferences(pref_data, Context.MODE_PRIVATE);
    driverPassword = preferences.getString("driverPassword","");
    carrierId = preferences.getString("carrierId","");
    cctid = preferences.getString("CCTID","");
    shipment = preferences.getString("shipment","");

    try
    {
        JSONObject shipmentObject = new JSONObject(shipment);
        shipmentID = shipmentObject.getString("ShipmentId");
    }
    catch(Exception e)
    {

    }

     powerManager = (PowerManager) getSystemService(Context.POWER_SERVICE);
     wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,
                "MyWakeLock");


     handler.removeCallbacks(sendWakeLock);
     handler.postDelayed(sendWakeLock, 1000); // 1 second   
     Log.w("onStart", "onStart");

     return  Service.START_NOT_STICKY;
}

@Override
public void onDestroy(){
    super.onDestroy();
    Log.w("onDestroy", "onDestroy");
    handler.removeCallbacks(sendWakeLock);
    SharedPreferences.Editor editor = preferences.edit();
    editor.putString("isDriverLogin", "True");
    editor.putString("driverPassword", driverPassword);
    editor.putString("carrierId", carrierId);
    editor.putString("CCTID", cctid);
    editor.putString("shipment", shipment);
    editor.putString("isAccepted", "");
    editor.putString("newshipment", "");
    editor.putString("isRemoved", "True");
    editor.commit();
}

注意：我的活动的 onDestroy 方法还有其他重要活动，我不想使用它。如果手机重新启动，我想利用我的服务发生的事件。我还设置了 Service.START_NOT_STICKY; 希望当手机重启或关机时，它会执行我的onDestroy。当我重新启动手机或我的服务在我重新启动手机时停止时，我应该如何在我的服务上捕获事件有什么想法吗？

在较新的版本下，服务将触发以下事件：

onCreate()
Followed by...

int onStartCommand(Intent intent, int flags, int startid)

// 确定我的一项服务当前是否正在运行

public static boolean isMyServiceRunning(Context context, String servicename) {
    ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
        if (servicename.equals(service.service.getClassName())) {
            return true;
        }
    }
    return false;
}
