не может быть добавлен в com.google.android.gms.common.api.GoogleApiClient $ ConnectionCallback

Question

Я пытаюсь сделать как в этом руководстве PushMe, но что-то не так.

неустранимым: Главный

java.lang.RuntimeException: Unable to start activity ComponentInfo{tk.i7otep9wka.testgeo/tk.i7otep9wka.testgeo.MainActivity}: java.lang.ClassCastException: tk.i7otep9wka.testgeo.MainActivity cannot be cast to com.google.android.gms.common.api.GoogleApiClient$ConnectionCallbacks 

MainActivity

package tk.i7otep9wka.testgeo; 

import android.support.v7.app.ActionBarActivity; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.MenuItem; 


import com.google.android.gms.common.ConnectionResult; 
import com.google.android.gms.common.GooglePlayServicesClient; 
import com.google.android.gms.common.api.GoogleApiClient; 
import com.google.android.gms.location.LocationServices; 


public class MainActivity extends ActionBarActivity implements 
     GooglePlayServicesClient.ConnectionCallbacks, 
     GooglePlayServicesClient.OnConnectionFailedListener { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     buildGoogleApiClient(); 
    } 


    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.menu_main, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 

     //noinspection SimplifiableIfStatement 
     if (id == R.id.action_settings) { 
      return true; 
     } 

     return super.onOptionsItemSelected(item); 
    } 
    protected synchronized void buildGoogleApiClient() { 
      GoogleApiClient mGoogleApiClient = new GoogleApiClient.Builder(this) 
       .addConnectionCallbacks((GoogleApiClient.ConnectionCallbacks) this) 
       .addOnConnectionFailedListener((GoogleApiClient.OnConnectionFailedListener) this) 
       .addApi(LocationServices.API) 
       .build(); 
    } 

    @Override 
    public void onConnected(Bundle bundle) { 

    } 

    @Override 
    public void onDisconnected() { 

    } 

    @Override 
    public void onConnectionFailed(ConnectionResult connectionResult) { 

    } 
} 

манифеста:

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="tk.i7otep9wka.testgeo" > 

    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> 

    <application 
     android:allowBackup="true" 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@style/AppTheme" > 
     <meta-data android:name="com.google.android.gms.version" 
      android:value="@integer/google_play_services_version" />

Answer 1

Сделайте свою деятельность реализацией GoogleApiClient.ConnectionCallbacks и GoogleApiClient.OnConnectionFailedListener вместо версии GooglePlayServiceClient. *.

Вы также можете удалить литой из buildGoogleApiClient() после реализации указанных выше интерфейсов.

 GoogleApiClient mGoogleApiClient = new GoogleApiClient.Builder(this) 
      .addConnectionCallbacks(this) 
      .addOnConnectionFailedListener(this) 
      .addApi(LocationServices.API) 
      .build(); 

Answer 2

public class MainActivity extends ActionBarActivity implements 
    GoogleApiClient.ConnectionCallbacks, 
    GoogleApiClient.OnConnectionFailedListener {} 

protected synchronized void buildGoogleApiClient() { 
     GoogleApiClient mGoogleApiClient = new GoogleApiClient.Builder(this) 
      .addConnectionCallbacks(this) 
      .addOnConnectionFailedListener(this) 
      .addApi(LocationServices.API) 
      .build(); 
}
