Emulador Android : Este aplicativo não será executado sem serviços Google Play

Desde Android 4.2.2 é possível executar os serviços do Google no emulador Android . Atualmente estou fazendo uma app Android e fez um projeto de teste para ver se eu posso obter Google+ login e cadastre -out para o trabalho.

Eu segui o seguinte tutorial:  http://www.androidhive.info/2014/02/android-login-with-google-plus-account-1/

Com a informação extra utilizado a partir dos seguintes tutoriais / sites :

https://developers.google.com/+/mobile/android/getting-started https://developers.google.com/+/mobile/android/sign-in http://developer.android.com/google/play-services/setup.html#Setup

Isso gerou o seguinte código:

AndroidManifest.xml :

LoadProfileImage.java :

import java.io.InputStream;

import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.AsyncTask;
import android.util.Log;
import android.widget.ImageView;

/**
 * Background async task to load user profile picture from url

public class LoadProfileImage extends AsyncTask<String, Void, Bitmap> {
    private ImageView bmImage;

    public LoadProfileImage(ImageView bmImage){
        this.bmImage = bmImage;
    }

    @Override
    protected Bitmap doInBackground(String... urls){
        String urlDisplay = urls[0];
        Bitmap mIcon11 = null;
        try{
            InputStream in = new java.net.URL(urlDisplay).openStream();
            mIcon11 = BitmapFactory.decodeStream(in);

            ex.printStackTrace();

        return mIcon11;
    }

    @Override
    protected void onPostExecute(Bitmap result){
        bmImage.setImageBitmap(result);
    }
}

Os outros passos que eu fiz foram :

No https://console.developers.google.com/project Eu criei um projeto com :

Google+ API on:

Emulador Android : Este aplicativo não será executado sem serviços Google Play

E um ID do cliente criado com o SHA1 correta e exatamente o mesmo espaço de nomes como o projeto:

Emulador Android : Este aplicativo não será executado sem serviços Google Play

At Eclipse:

Eu instalei a biblioteca google- play- serviços :

Emulador Android : Este aplicativo não será executado sem serviços Google Play

E acrescentou que para o projeto:

Emulador Android : Este aplicativo não será executado sem serviços Google Play  Emulador Android : Este aplicativo não será executado sem serviços Google Play

Também criei um emulador com a versão 4.4.2 :

Emulador Android : Este aplicativo não será executado sem serviços Google Play

Mas quando eu executar o aplicativo eu recebo o seguinte erro, e esse erro continua aparecendo quando eu clico no botão :

Emulador Android : Este aplicativo não será executado sem serviços Google Play

Alguém tem alguma idéia de onde ele está errado ? Agradecemos antecipadamente para as respostas .

Tente usar o nível API Goole APIs 19 como alvo emulador em vez de nível API normal de 19 .

2Kevin Cruijssen @

Ok, depois de tentar algumas coisas acabou que eu tinha uma última opção não corretamente marcada, que não foi mencionado em qualquer parte do tutorial (s) ..

Em vez de Android 4.4.2 como Projeto Construir alvo & amp; Emulator Target, eu selecionei Google APIs 4.4.2 . Agora eu não recebo o erro dos serviços do Google jogar mais.

Eu fico um NullPointerException embora, mas pelo menos eu posso continuar ..; )

EDIT: Corrigido o NullPointerException e modificou o código no meu post original . Tudo funciona como deveria agora e espero que este post ajude outras pessoas com os erros mesmo (ou outro ) que utilizam os serviços do Google Play login usando um emulador Android .
