Question

¿Cómo obtener el registrationId?

siempre consigo el error ACCOUNT_MISSING

MainActivity

package com.example.gcm; 
import android.os.Bundle; 
import android.app.Activity; 
import android.util.Log; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.support.v4.app.NavUtils; 
import com.google.android.gcm.GCMRegistrar; 

public class MainActivity extends Activity { 

    private static final String SENDER_ID = "45552950387"; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     GCMRegistrar.checkDevice(this); 
     GCMRegistrar.checkManifest(this); 
     final String regId = GCMRegistrar.getRegistrationId(this); 
     if (regId.equals("")) { 
      GCMRegistrar.register(this, SENDER_ID); 
      Log.d("show", "Already registered1"+regId); 
     } else { 
      Log.d("show", "Already registered"); 
     } 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.menu.activity_main, menu); 
     return true; 
    } 


} 

GCMIntentService

package com.example.gcm; 

import android.app.Notification; 
import android.app.NotificationManager; 
import android.app.PendingIntent; 
import android.content.Context; 
import android.content.Intent; 
import android.util.Log; 
import com.google.android.gcm.GCMBaseIntentService; 

public class GCMIntentService extends GCMBaseIntentService { 
    private static final String TAG = "GCMIntentService"; 

    public GCMIntentService() { 
     super("45552950387"); 
    } 

    @Override 
    protected void onRegistered(Context context, String registrationId) { 
     Log.i(TAG, "Device registered: regId = " + registrationId); 
    } 

    @Override 
    protected void onUnregistered(Context context, String registrationId) { 
     Log.i(TAG, "Device unregistered"); 
    } 

    @Override 
    protected void onMessage(Context context, Intent intent) { 
     Log.i(TAG, "Received message"); 
     String a = intent.getStringExtra("A"); 
     generateNotification(context, a); 
    } 

    @Override 
    protected void onDeletedMessages(Context context, int total) { 
     Log.i(TAG, "Received deleted messages notification"); 

    } 

    @Override 
    public void onError(Context context, String errorId) { 
     Log.i(TAG, "Received error: " + errorId); 

    } 

    @Override 
    protected boolean onRecoverableError(Context context, String errorId) { 
     Log.i(TAG, "Received recoverable error: " + errorId); 
     return super.onRecoverableError(context, errorId); 
    } 

    private void generateNotification(Context context, String message) { 

     NotificationManager notificationManager = (NotificationManager) context 
       .getSystemService(NOTIFICATION_SERVICE); 

     Notification notification = new Notification(); 
     notification.icon = R.drawable.ic_launcher; 
     notification.tickerText = "notification on status bar."; 
     notification.defaults = Notification.DEFAULT_ALL; 
     notification.setLatestEventInfo(context, "Title", message, null); 
     notificationManager.notify(0, notification); 
    } 
}

Answer 1

error ACCOUNT_MISSING cuando no hay ninguna cuenta de Google en el teléfono.

No hay una cuenta de Google en el teléfono. La aplicación de Android debe solicitar al usuario que abra el administrador de cuenta y agregue una cuenta Google . Fix en el lado del dispositivo.
