NPE at com.vk.sdk.VKSdk.isLoggedIn() at com.github.gorbin.asne.vk.VkSocialNetwork.isConnected()

I get a NullPointerException when calling VkSocialNetwork.isConnected()

java.lang.NullPointerException: Attempt to read from field 'com.vk.sdk.VKAccessToken com.vk.sdk.VKSdk.mAccessToken' on a null object reference

Might be too late, but i just hit the same problem - make sure that getFragmentManager().beginTransaction().add(mSocialNetworkManager, MainActivity.SOCIAL_NETWORK_TAG).commit(); is called in your fragment
