Problemi di implementazione del nuovo client GCM per Android

Question

Sto cercando di implementare il nuovo GCM Client su Android seguendo le linee guida di Google (https://developers.google.com/cloud-messaging/android/client). Ricevo errori leggermente diversi per due dispositivi diversi. Ho notato che ricevo NoSuchMethodError per il metodo getNoBackupFilesDir per entrambi i dispositivi.
Questa è la logcat per un Android 4.2.2:

In linea 113 ho questo:

InstanceID instanceID = InstanceID.getInstance(applicationContext); 

Utilizzato qui:

// AsyncTask to register Device in GCM Server 
private void registerInBackground() { 
    new AsyncTask<Void, Void, String>() { 
     @Override 
     protected String doInBackground(Void... params) { 
      String msg = ""; 

      InstanceID instanceID = InstanceID.getInstance(applicationContext); 
      try { 
       regId = instanceID.getToken(GCM_SENDER_ID, 
         GoogleCloudMessaging.INSTANCE_ID_SCOPE, null); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 

      return msg; 
     } 

     @Override 
     protected void onPostExecute(String msg) { 
      if (!TextUtils.isEmpty(regId)) { 

       Toast.makeText(
         applicationContext, 
         "Registered with GCM Server successfully.\n\n" 
           + msg, Toast.LENGTH_SHORT).show(); 
       Log.e(TAG, "Registered with GCM Server successfully. RegID: " + regId); 

      } else { 
       Toast.makeText(
         applicationContext, 
         "Reg ID Creation Failed.\n\nEither you haven't enabled Internet or GCM server is busy right now. " 
         + "Make sure you enabled Internet and try registering again after some time." 
           + msg, Toast.LENGTH_LONG).show(); 
       Log.e(TAG, "Reg ID Creation Failed!!!"); 
      } 
     } 
    }.execute(null, null, null); 
} 

Ho importato correttamente la libreria Google Play Services come descritto nella documentazione. (https://developers.google.com/android/guides/setup)

Qualcuno ha riscontrato questo errore? Come posso risolvere questo?

Ambiente di sviluppo utilizzato: Eclipse Kepler SR2 con ADT
Se sono necessarie ulteriori informazioni, si prega di commentare.

Answer 1

Ho visto che il metodo getNoBackupFilesDir si trova in android.support.v4.content.ContextCompat.

Sembra che il problema era che avevo un vecchio appcompat-v7 incluso nel progetto. Scaricare con SDK manager l'ultima versione di Android Support Library e quindi seguire i passaggi per Adding libraries with resources e aggiungere la libreria al progetto dell'applicazione.

Answer 2

ho ottenuto questo errore:

java.lang.NoSuchMethodError: No static method getNoBackupFilesDir(Landroid/content/Context;)Ljava/io/File; in class Lcom/google/android/gms/common/util/zzx; or its super classes (declaration of 'com.google.android.gms.common.util.zzx' appears in /data/data/com.crave.iapdemo/files/instant-run/dex/slice-com.google.android.gms-play-services-basement-10.0.1_b9da1447b99cc6cbc2fa601fb84d0418780bfa55-classes.dex)

                     at vodio.labs.crave.gcm.RegistrationIntentService.onHandleIntent(RegistrationIntentService.java:39) 

in questa linea:

InstanceID.getInstance(this); 

La soluzione per me è stato l'aggiornamento questo:

dependencies { 
    // play services 
    compile 'com.google.android.gms:play-services-gcm:9.0.0' 
    compile 'com.google.android.gms:play-services-analytics:9.0.0' 
} 

in:

dependencies { 
    // play services 
    compile 'com.google.android.gms:play-services-gcm:10.0.1' 
    compile 'com.google.android.gms:play-services-analytics:10.0.1' 
}
