Android服务意图为空

我有一个在后台运行的服务。它在舱单中登记。当我从活动中向它传递几个字符串并启动它时，意图为null。我已经检查了字符串，它们在发送到服务之前不为空。知道为什么意图是无效的吗？ 这是那个片段

                Intent iniupdates = new Intent(MapActivity.this, InitialLocationUpdater.class);
                iniupdates.setAction("mypackage.InitialLocationUpdater");
                iniupdates.putExtra(InitialLocationUpdater.PARAM_IN_PAS, psgr);
                iniupdates.putExtra(InitialLocationUpdater.PARAM_IN_DRI, tok);
                //iniupdates.putExtra("lat", la);
                //iniupdates.putExtra("lon", lo);
                Log.e("testma600", tok + psgr);
                startService(iniupdates);

下面是服务的onstartCommand方法

@Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        try {
            if (null == intent || intent.equals(null) || intent.getData() == null){Log.e("Log", "the intent in onStartCommand is null");}
            else if (intent.getStringExtra(PARAM_IN_PAS) != null && intent.getStringExtra(PARAM_IN_DRI) != null && mLastLocation != null) {
            pass = intent.getStringExtra(PARAM_IN_PAS);
            driv = intent.getStringExtra(PARAM_IN_DRI);
            //String lat = intent.getStringExtra("lat");
            //String lon = intent.getStringExtra("lon");
            sendLocation(driv, String.valueOf(mLastLocation.getLatitude()), String.valueOf(mLastLocation.getLongitude()), pass);
            }
        }catch (Exception e){
            e.printStackTrace();
            Log.e("ERROR", driv +  String.valueOf(mLastLocation.getLatitude()));
        }
        return START_NOT_STICKY;
    }

我还在堆栈跟踪中的BufferReader行上看到以下异常，我已经发布了

@Override
            protected Void doInBackground(String... args) {
                try {

                        json.put("drlon", args[2]);

                        String postData=json.toString();

                        // Send POST output.
                        OutputStreamWriter os = new OutputStreamWriter(urlConn.getOutputStream(), "UTF-8");

                        while ((line = reader.readLine()) != null) {

                        Log.i("msg=",""+msg);
                    } catch (MalformedURLException muex) {
                        // TODO Auto-generated catch block
                        muex.printStackTrace();
                    } catch (IOException ioex){
                        ioex.printStackTrace();
                    } 
                } catch (Exception e) {
                    e.printStackTrace();
                    Log.e("ERROR", "There is error in this code " + String.valueOf(args[0]));

                }
                return null;
            }

这是堆栈跟踪

堆栈跟踪显示URL无效！和连接失败（连接超时）

在代码中，您处理了null intent

 if (null == intent || intent.equals(null) || intent.getData() == null){Log.e("Log", "the intent in onStartCommand is null");}

在第一步中，请检查URL。 要将数据发送到您的服务，请更改创建意图，如下所示：

Intent iniupdates = new Intent(MapActivity.this, InitialLocationUpdater.class);
Bundle bundle = new Bundle();        
bundle.putString(InitialLocationUpdater.PARAM_IN_PAS, psgr);        
bundle.putString(InitialLocationUpdater.PARAM_IN_DRI, tok);   

iniupdates.putExtras(bundle);
startService(iniupdates);

在您的服务中，使用以下代码检索数据：

Bundle bundle = intent.getExtras();

if (bundle != null)
{
   String psgr = bundle.getString(PARAM_IN_PAS);
   String tok = bundle.getString(PARAM_IN_DRI);
}

---

结果是

sendLocation（）

方法在服务中执行了较长的进程，因此系统引发了

networkonmainthread

异常，这是基于

我创建了一个嵌套在服务类中的新的

AsyncTask

类，并在其中执行了所有长操作

---

现在我不再有空的意图了。我不明白为什么。我从未想过

networkMainThread

异常可能是这背后的原因。

如果stacktrace显示的是“未能连接到/192.168.0.44（端口80）：连接失败：ETIMEDOUT（连接超时）”，如何传递Intent null？我想从嵌套异步任务的mapactivity启动服务。服务类位于单独的java文件中。这里的asyncTask与启动服务无关。我感谢您的帮助。然而，我仍然得到零意图。我猜这与我的另一个应用程序发送数据有关，因此触发了已经超时的asyncTask。它比我的代码片段更复杂。我正在解决它，如果我解决了它，我将进行更新。：）
