    Fragment fragment = getSupportFragmentManager().findFragmentByTag(SOCIAL_NETWORK_TAG);
    if (fragment != null) {
        fragment.onActivityResult(requestCode, resultCode, data);
    }
}

• Возьмем ключи социальных сетей из values.xml
  
  

  String VK_KEY = getActivity().getString(R.string.vk_app_id);
  String OK_APP_ID = getActivity().getString(R.string.ok_app_id);
  String OK_PUBLIC_KEY = getActivity().getString(R.string.ok_public_key);
  String OK_SECRET_KEY = getActivity().getString(R.string.ok_secret_key);
  

  
  
• Получим SocialNetworkManager
  
  

  mSocialNetworkManager = (SocialNetworkManager) getFragmentManager().findFragmentByTag(MAinActivity.SOCIAL_NETWORK_TAG);
  

  
  
• Создадим SocialNetworks с соответствующими разрешениями:
  
  

  String[] vkScope = new String[] {
  	VKScope.FRIENDS,
      VKScope.WALL,
  	VKScope.PHOTOS,
      VKScope.NOHTTPS,
      VKScope.STATUS,
  };
  VkSocialNetwork vkNetwork = new VkSocialNetwork(this, VK_KEY, vkScope);
  
  String[] okScope = new String[] { 
  	OkScope.VALUABLE_ACCESS
  };
  OkSocialNetwork okNetwork = new OkSocialNetwork(this, OK_APP_ID, OK_PUBLIC_KEY, OK_SECRET_KEY, okScope);     
  

  
  
• Проверим существует ли SocialNetworkManager
  
  • Если не существует зададим его и добавим в него SocialNetworks
    
    

    mSocialNetworkManager = new SocialNetworkManager();
        
    mSocialNetworkManager.addSocialNetwork(vkNetwork);
    mSocialNetworkManager.addSocialNetwork(okNetwork);
        
    //Initiate every network from mSocialNetworkManager
    getFragmentManager().beginTransaction().add(mSocialNetworkManager, MAinActivity.SOCIAL_NETWORK_TAG).commit();
    mSocialNetworkManager.setOnInitializationCompleteListener(this);
    

    
    
  • Если SocialNetworkManager существует(задали в activity или другом фрагменте) — выберем все инициализированные социальные сети и установим им OnLoginCompleteListener
    
    

    if(!mSocialNetworkManager.getInitializedSocialNetworks().isEmpty()) {
    	List<SocialNetwork> socialNetworks = mSocialNetworkManager.getInitializedSocialNetworks();
        for (SocialNetwork socialNetwork : socialNetworks) {
            socialNetwork.setOnLoginCompleteListener(this);
        }
    

    
    
• Теперь необходимо обработать ответ после инициации SocialNetworks
  
  

  @Override
  public void onSocialNetworkManagerInitialized() {
  	for (SocialNetwork socialNetwork : mSocialNetworkManager.getInitializedSocialNetworks()) {
  		socialNetwork.setOnLoginCompleteListener(this);
  		initSocialNetwork(socialNetwork);
  	}
  }
