Facebook Android API asks for additional permission

Tag: android,facebook,facebook-graph-api

I am using v2.3 api here I can login with Facebook login button. Now how can I call additional permission on click? I have looked through answers for this question, but all of them look to be back-dated.

Can someone show me the right way of asking for addition permission and perform further action(s) based on that?

I am able to get the user's basic info and I now need need post permission to post something in user's wall

FacebookSdk.sdkInitialize(getApplicationContext());
CallbackManager callbackManager = CallbackManager.Factory.create();
LoginButton loginButton = (LoginButton) this.findViewById(R.id.login_button);


loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
   AccessToken act = loginResult.getAccessToken();

}
});

Best How To :

Use the loginManager to add more permission. you can add it on click button or on create view or fragment

LoginManager.getInstance().logInWithReadPermissions(
    fragmentOrActivity,
    Arrays.asList("user_friends"));

You can also get AccessToken via following if needed after getting new permission

AccessToken.getCurrentAccessToken()
