login Facebook registerCallback not called

Question

Here is my onCreate method:

@Override protected void onCreate(Bundle bundle) {     super.onCreate(bundle);     setContentView(R.layout.activity_social_login);     init();     hideActiveSocialNetworks();     FacebookSdk.sdkInitialize(getApplicationContext());     CallbackManager callbackManager = CallbackManager.Factory.create();     LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {         @Override         public void onSuccess(LoginResult loginResult) {             // not called             Log.d("fb_login_sdk", "callback success");         }          @Override         public void onCancel() {             // not called             Log.d("fb_login_sdk", "callback cancel");         }          @Override         public void onError(FacebookException e) {             // not called             Log.d("fb_login_sdk", "callback onError");         }     });      final Activity activity = this;      findViewById(R.id.fb_login_sdk).setOnClickListener(new View.OnClickListener() {         @Override         public void onClick(View view) {             Log.d("fb_login_sdk", "click");             List<String> perm = new ArrayList<String>();             perm.add("user_friends");             LoginManager.getInstance().logInWithReadPermissions(activity, perm);         }     }); } 

After login the onSuccess(), onCancel(), onError() methods are not fired.

Missing this on my activity:

   @Override     public void onActivityResult(int requestCode, int resultCode, Intent data) {         super.onActivityResult(requestCode, resultCode, data);         callbackManager.onActivityResult(requestCode, resultCode, data);     }

Here is checklist to check whether your Facebook Sdk setup is correct:-

1. Check your manifest if you have setup Facebook initialization properly.

   <meta-data android:name="com.facebook.sdk.ApplicationId"     android:value="@string/facebook_app_id" />  <activity android:name="com.facebook.FacebookActivity"     android:configChanges=             "keyboard|keyboardHidden|screenLayout|screenSize|orientation"     android:label="@string/app_name" /> <activity     android:name="com.facebook.CustomTabActivity"     android:exported="true">     <intent-filter>         <action android:name="android.intent.action.VIEW" />         <category android:name="android.intent.category.DEFAULT" />         <category android:name="android.intent.category.BROWSABLE" />         <data android:scheme="@string/fb_login_protocol_scheme" />     </intent-filter> </activity> 

2. Create Facebook CallBackManager variable

   var fbCallManager = CallbackManager.Factory.create() 

3. On Click of Login with Facebook button. Put your required permission in Array.

     LoginManager.getInstance()     .logInWithReadPermissions(this, Arrays.asList("public_profile", "email", "user_friends"))   LoginManager.getInstance().registerCallback(fbCallManager, object : FacebookCallback<LoginResult> {     override fun onSuccess(result: LoginResult?) {        //login success     }      override fun onCancel() {         //login cancelled by user      }      override fun onError(error: FacebookException?) {         //login error handle exception     }  }) 

   }

4. Add callback result in onActivityResult method

   override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {     super.onActivityResult(requestCode, resultCode, data)     fbCallManager.onActivityResult(requestCode, resultCode, data) } 

5. Provide the Development and Release Key Hashes for Your

   keytool -exportcert -alias androiddebugkey -keystore "C:\Users\USERNAME.android\debug.keystore" | "PATH_TO_OPENSSL_LIBRARY\bin\openssl" sha1 -binary | "PATH_TO_OPENSSL_LIBRARY\bin\openssl" base64

Download openssl from here

6. Setup your Keyhash and Launcher activity in Facebook developer console.
