Facebook Login CallbackManager FacebookCallback called onCancel() every time

Question

I am implementing login via facebook and get user email id using SDK 4.1.0 as shown in facebook documentation but problem occurring is that every time after onActivityResult when registerCallback is called then instead of onSuccess onCancel is called.

package com.dexterous.hellologin;

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.util.Log;

import com.facebook.CallbackManager;
import com.facebook.FacebookCallback;
import com.facebook.FacebookException;
import com.facebook.FacebookSdk;
import com.facebook.login.LoginResult;
import com.facebook.login.widget.LoginButton;


public class MainActivity2 extends ActionBarActivity {

CallbackManager callbackManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


    FacebookSdk.sdkInitialize(getApplicationContext());
    callbackManager = CallbackManager.Factory.create();

    setContentView(R.layout.activity_main_activity2);

    LoginButton loginButton = (LoginButton) findViewById(R.id.login_button);
    loginButton.setReadPermissions("email");
    // If using in a fragment
    //   loginButton.setFragment(this);
    // Other app specific specialization
    // Callback registration
        loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            // App code
            Log.e("TAG", "success");
        }

        @Override
        public void onCancel() {
            // App code
            Log.e("TAG", "onCancel");
        }

        @Override
        public void onError(FacebookException exception) {
            // App code
            Log.e("TAG", "error");
        }
    });
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    callbackManager.onActivityResult(requestCode, resultCode, data);
    Log.e("TAG", "onActivityResult");
   }
}

every time i am getting output

onActivityResult

onCancel

neither i am getting that facebook login screen containing buttons cancel and login.

after uninstall facebook app from mobile error changed to Invalid App ID

and this is stacktrace

Answer 1

I noticed that the onCancel() is still called because user is already logged on. try calling LoginManager.getInstance().logOut() before initiating your login sequence

Answer 2

Problem is here that you are using Facebook APPId directly and You should use Like this

<meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:value="@string/app_id" />

In sting xml

<string name="app_id">1437829111203883 </string>
