我有一个重要的交货，我希望你能帮助我。

我必须使用 GCM。我正在使用http://developer.android.com/guide/google/gcm/demo.html官方指南中的文件

我做了“使用 App Engine for Java 设置服务器”并且它工作。

我的问题是 android 应用程序。确切地说，我没有从 GCM 接收 id，所以任何时候我的应用程序都尝试注册。

非常感谢....

public class DemoActivity extends Activity {

    TextView mDisplay;
    AsyncTask<Void, Void, Void> mRegisterTask;

    @Override
     public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        checkNotNull(SERVER_URL, "SERVER_URL");
        checkNotNull(SENDER_ID, "SENDER_ID");

        // Make sure the device has the proper dependencies.
        GCMRegistrar.checkDevice(this);
        // Make sure the manifest was properly set - comment out this line
        // while developing the app, then uncomment it when it's ready.
        GCMRegistrar.checkManifest(this);
        setContentView(R.layout.main);
        mDisplay = (TextView) findViewById(R.id.display);
        registerReceiver(mHandleMessageReceiver,
                new IntentFilter(DISPLAY_MESSAGE_ACTION));
        final String regId = GCMRegistrar.getRegistrationId(this);
       if (regId.equals("")) {

            // Automatically registers application on startup.
            GCMRegistrar.register(this, SENDER_ID);

        } else {
            ....
        }

通用工具 

public final class CommonUtilities 
{
     static final String SERVER_URL = "http://127.0.0.1:8888/gcmdemo4/home";
     static final String SENDER_ID = "843761346XXX";
...
}

GCMIntentService 

public class GCMIntentService extends GCMBaseIntentService {

@SuppressWarnings("hiding")
private static final String TAG = "GCMIntentService";

public GCMIntentService() {
    super(SENDER_ID);
}

@Override
public void onRegistered(Context context, String registrationId) {
    Log.i(TAG, "Device registered: regId = " + registrationId);
    displayMessage(context, getString(R.string.gcm_registered));
    ServerUtilities.register(context, registrationId);
}
 .....

你能提供你的“registerReceiver”代码吗？

当我的 SENDER_ID 错误时，我遇到了同样的问题。尝试再次检查它，并检查你的包： com.example.registrazionegcm.GCMIntentService 在 onError 和 onRegistered 中放置一些断点

对我来说，这段代码有效：

@Override
public void run() {

    GCMRegistrar.checkDevice(mContext);
    GCMRegistrar.checkManifest(mContext);
    String deviceToken = GCMRegistrar.getRegistrationId(mContext);
    if (deviceToken.equals("")) {
        GCMRegistrar.register(mContext, "XXXXXXXXXXXXXXX");
        deviceToken = GCMRegistrar.getRegistrationId(mContext);
        if(!deviceToken.equals("")){
            GCMRegistrar.setRegisteredOnServer(mContext, true);
            // register deviceToken on CommNotes srv
            RequestMaker req = new RequestMaker(Constant.REQ_REGISTER_GCM, mContext);
            //if unsuccessful, try again 5 times
            for(int i = 0; i<5; i++){
                Log.d("ComNotes", "registration id"+deviceToken);
                if(req.doRequest(deviceToken) == ReturnCode.CODE_OK){
                    break;
                }             
            }
        }
        //TODO manage unsuccess: display error : "No PUSH available"
    } else {
        Log.v("CommunityNotes", "Already registered "+deviceToken);
    }
}
