FacebookCallback.onCancel is getting called when trying to login using facebook sdk

Question

I have an Android app and I am trying to use Facebook's SDK (version 4.1.0) to get a token and log in. Here is my code:

public class LoginActivity extends Activity {     private CallbackManager callbackManager;      @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_login);         FacebookSdk.sdkInitialize(getApplicationContext());          callbackManager = CallbackManager.Factory.create();         LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {             @Override             public void onSuccess(LoginResult loginResult) {                 AccessToken accessToken = loginResult.getAccessToken();                 Log.v(TAG, "Facebook login was successful");                 String authToken = accessToken.getToken();                 // User authToken here:             }              @Override             public void onCancel() {                 Log.v(TAG, "Facebook login was canceled");             }              @Override             public void onError(FacebookException e) {                 Log.e(TAG, "Facebook login failed: " + e.getMessage());             }         });          Button facebook_button = (Button) findViewById(R.id.fbButton);          facebook_button.setOnClickListener(new View.OnClickListener() {             public void onClick(View v) {                 LoginManager.getInstance().logInWithReadPermissions(getActivity(), Arrays.asList("public_profile"));             }         });      }      @Override     public void onActivityResult(int requestCode, int resultCode, Intent data) {         super.onActivityResult(requestCode, resultCode, data);         callbackManager.onActivityResult(requestCode, resultCode, data);     } } 

The code switched to the Facebook app and back and OnActivityResult() is called. However, every time the callback method that is called is onCancel(). Note that I am not using the LoginButton provided by Facebook, and I have my own button (although I tried that approach and the result was the same). I double and triple checked my app ID and the keyhash generated by the app and they look correct too. So, I don't know what else may be wrong. Any help at this point is greatly appreciated.

Answer 1

yes i was facing the same issue, resolved it by using the below code just before login

 LoginManager.getInstance().logOut();
