新的GCM API注册未知源错误

我目前正在构build一个使用新的Google云消息传递系统的应用程序。 我有一个HTTP客户端服务器设置在一个实时环境,以允许我通过我的移动设备进行testing,但是当我尝试注册GCM时,我不断收到一个IOException,指出gcm.register()正在接收一个未知源阻止我获得注册ID我需要让我的服务器发送消息到我的设备。

我已经多次查了一下,看看我的发件人ID是否是错的,我也检查了我的清单,看看我是否也有这个错误,我似乎无法find问题。 环顾四周也没有提供任何答案我的问题。

这是我的日志:

这是你得到的错误:

 java.io.IOException: MAIN_THREAD 

这意味着你正在从主线程调用注册方法,这是不允许的。 你应该从另一个线程调用它。

公共静态最终stringERROR_MAIN_THREAD

GCM方法正在阻塞。 您不应该在主线程或广播接收器中运行它们。 常量值:“MAIN_THREAD”

以下是GCM文档中的代码示例:

 /** * Registers the application with GCM servers asynchronously. * <p> * Stores the registration id, app versionCode, and expiration time in the * application's shared preferences. */ private void registerBackground() { new AsyncTask() { @Override protected String doInBackground(Void... params) { String msg = ""; try { if (gcm == null) { gcm = GoogleCloudMessaging.getInstance(context); } regid = gcm.register(SENDER_ID); msg = "Device registered, registration id=" + regid; // You should send the registration ID to your server over HTTP, // so it can use GCM/HTTP or CCS to send messages to your app. // For this demo: we don't need to send it because the device // will send upstream messages to a server that echo back the message // using the 'from' address in the message. // Save the regid - no need to register again. setRegistrationId(context, regid); } catch (IOException ex) { msg = "Error :" + ex.getMessage(); } return msg; } @Override protected void onPostExecute(String msg) { mDisplay.append(msg + "\n"); } }.execute(null, null, null); } 

1.创buildGCMHelper类来获取CGM ID。

 public final class GCMHelper { static GoogleCloudMessaging gcm = null; static Context context= null; public GCMHelper (Context context) { this.context= context; } public String GCMRegister (String SENDER_ID) throws Exception { String regid = ""; //Check if Play store services are available. if(!checkPlayServices()) throw new Exception("Google Play Services not supported. Please install and configure Google Play Store."); if (gcm == null) { gcm = GoogleCloudMessaging.getInstance(context); } regid = gcm.register(SENDER_ID); return regid; } private static boolean checkPlayServices() { int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(context); if (resultCode != ConnectionResult.SUCCESS) { return false; } return true; } } 

2. 然后在Activity中创buildGetGCM()方法。

 //**To avoid java.io.IOException: MAIN_THREAD** private void GetGCM() { Thread thread = new Thread(new Runnable() { @Override public void run() { try { GCMHelper gcmRegistrationHelper = new GCMHelper ( getApplicationContext()); String gcmRegID = gcmRegistrationHelper.GCMRegister(SENDER_ID); } catch (Exception bug) { bug.printStackTrace(); } } }); thread.start(); } 

3.然后调用GetGCM()方法,无论你想要的。

4.快乐的编码…
