Google Cloud Messaging等待注册

Question

In my GCM project, I want to wait for AsyncTask until the register returns.

I've tried to use synchronized and CountDownLatch to wait in the main thread.

However, every time I wait, my app exits with exception SERVICE_NOT_AVAILABLE on register method.

Why does this exception occur? I get a perfectly fine registration ID normally. Also, the waiting process is successful without the register method.

Thx for your help in advance.

Answer 1

The SERVICE_NOT_AVAILABLE error comes often with the GCM register() method. You can try the following:

1. Add REGISTRATION to the GcmBroadcastReceiver Intent Filter in AndroidManifest.xml file

   <receiver android:name=".GcmBroadcastReceiver" android:permission="com.google.android.c2dm.permission.SEND" > <intent-filter> <action android:name="com.google.android.c2dm.intent.RECEIVE" /> <action android:name="com.google.android.c2dm.intent.REGISTRATION" /> <category android:name="YOUR_PACKAGE_NAME" /> </intent-filter> </receiver>

2. Obtain the Registration ID in GcmBroadcastReceivers onReceive method

   @Override

   public void onReceive(Context context, Intent intent) {

    String regId = intent.getExtras().getString("registration_id"); 

   }

Hope this works for you.
