08-28 16:42:29.665 22669-22705/com.my.app E/Answers﹕ Failed to retrieve settings 

Ecco la mia classe di applicazione:

... 
    @Override 
    public void onCreate() { 
     super.onCreate(); 
     //Initiate SDKs 
     Fabric.with(this, new Crashlytics()); //Crashlytics 
     FacebookSdk.sdkInitialize(this);  //Facebook 
     registerParse();      //Parse 
... 

Answer 1

Fondamentalmente la connessione non funziona ...

Resons potrebbe essere:

1. Problemi di connessioni usuali

2. Altri software che blocca (adblockers)/(verificare che in primo luogo, un problema comune)

3. approssimazioni o alcune impostazioni porta specifici

4. Possibilmente ci sono molti altri ...

È difficile dire quale potrebbe essere la ragione in questo caso. Vorrei provare diverse condizioni.
