如何註冊gcm從gcm獲得註冊ID

Question

我想在我的項目中使用GCM我讀到關於GCM的內容我瞭解它的工作原理，但是當我無法理解我們如何執行代碼以獲取註冊身份證表格GCM你可以給我完整的代碼從GCM獲取註冊ID，請不要說這樣做谷歌。 請給我代碼如何在GCM上註冊，我如何從GCM獲得註冊ID。

在這裏，你去。

private void registerInBackground() { 

    gcmRegistrationInProcces = true; 

    new AsyncTask<Void, Void, String>() { 

     @Override 
     protected String doInBackground(Void... params) { 
      String msg = ""; 
      try { 
       if (Application.gcm == null) { 
        Application.gcm = GoogleCloudMessaging.getInstance(getApplicationContext()); 
       } 
       GCM_REGISTRATION_ID = Application.gcm.register(GCM_SENDER_ID); 
       msg = "Device registered, registration ID=" + GCM_REGISTRATION_ID; 

       // 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. 
       sendRegistrationIdToBackend(); 

       // 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. 

       // Persist the regID - no need to register again. 
       storeRegistrationId(getApplicationContext(), GCM_REGISTRATION_ID); 
      } catch (IOException ex) { 
       msg = "Error :" + ex.getMessage(); 
       // If there is an error, don't just keep trying to register. 
       // Require the user to click a button again, or perform 
       // exponential back-off. 
      } 

      return msg; 
     } 

     @Override 
     protected void onPostExecute(String s) { 
      gcmRegistrationInProcces = false; 

      super.onPostExecute(s); 
     } 

     @Override 
     protected void onPostExecute(String msg) 
     { 
      Toast.makeText(getBaseContext(), "Registered with REG_ID:\n"+GCM_REGISTRATION_ID, Toast.LENGTH_SHORT).show(); 
     } 
    }.execute(null, null, null); 
}
