Question

我一直在寻找几天，似乎很多人遇到了同样的问题。

我尝试在我的设备中注册我的应用程序以从GCM获取ID。我提到androidhive。

我无法使用GCMRegistrar.register（this，SENDER_ID）获取ID，我仔细检查了我的发件人ID，这是正确的。

public class MainActivity extends Activity {
boolean flag=false;
AsyncTask<Void, Void, Void> mRegisterTask;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // Device is already registered on GCM
    GCMRegistrar.checkDevice(this);

    GCMRegistrar.checkManifest(this);
    registerReceiver(mHandleMessageReceiver, new IntentFilter(
            DISPLAY_MESSAGE_ACTION));
    final String regId = GCMRegistrar.getRegistrationId(this);
             Log.v("RegId", regId);
    if (regId.equals("")) {

        GCMRegistrar.register(this, SENDER_ID);
    } else {

        if (GCMRegistrar.isRegisteredOnServer(this)) {

            Toast.makeText(getApplicationContext(), "Already registered with GCM", Toast.LENGTH_LONG).show();
        } else {


            mRegisterTask = new AsyncTask<Void, Void, Void>() {

                @Override
                protected Void doInBackground(Void... params) {

                     Map<String, String> prms=new HashMap<String, String>();
                     prms.put("regId", regId);
                    try {
                        post(SERVER_URL,prms);
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    return null;
                }

                @Override
                protected void onPostExecute(Void result) {
                    mRegisterTask = null;
                }

            };
            mRegisterTask.execute(null, null, null);
        }
    }

GCM intent服务写在主包

中

public class GCMIntentservice extends GCMBaseIntentService{

private static final String TAG = "GCMIntentService";

public GCMIntentservice() {
    super(SENDER_ID);
}


@Override
protected void onError(Context arg0, String arg1) {
    // TODO Auto-generated method stub

}

@Override
protected void onMessage(Context arg0, Intent arg1) {
    // TODO Auto-generated method stub

}

@Override
protected void onRegistered(Context arg0, String arg1) {
        // TODO Auto-generated method stub
     Log.i(TAG, "Device registered: regId = " + arg1);

}

@Override
protected void onUnregistered(Context arg0, String arg1) {
    // TODO Auto-generated method stub  
    Log.i(TAG, "Device unregistered");  } }

这是我的清单

它甚至没有在详细信息中显示Log.v("RegId", regId);。

Answer 1

当我将意图服务类重命名为GCMIntentService时，以及在清单.GCMIntentService中，我能够在详细信息中获取注册ID

Answer 2

GCMRegistrar属于不推荐使用的库。它应该仍然有效，但你正确地使用它。 GCMRegistrar.register是异步的。注册ID通过BroadcastReceiver返回onRegistered GCMIntentService方法。但是，您的onRegistered方法对该注册ID不执行任何操作，因此GCMRegistrar永远不会将其保存在本地，也不会发送到您的服务器。

您不应该使用旧教程作为示例。使用new GCM Client Demo，其中显示了如何使用新注册方法（使用GoogleCloudMessaging.register库的GooglePlayServices）。

GCMRegistrar.register（this，SENDER_ID）;正在显示注册应用程序com.example.fbbookresale的发件人742646281XXX
