How can I get Access Token and other info correctly after logging in Facebook App and authorizing my app? [Android]

Question

I'm using this. In my Facebook.java in my authorized() method I call startSingleSignOn and startDialogAuth, I'm using the DEFAULT_AUTH_ACTIVITY_CODE instead of FORCE_DIALOG_AUTH

public void authorize(Activity activity, String[] permissions, int activityCode, final DialogListener listener) {

    boolean singleSignOnStarted = false;

    mAuthDialogListener = listener;

    // Prefer single sign-on, where available.
    if (activityCode >= 0) {
        singleSignOnStarted = startSingleSignOn(activity, mAppId,
                permissions, activityCode);
    }
    // Otherwise fall back to traditional dialog.
    if (!singleSignOnStarted) {
        startDialogAuth(activity, permissions);
    }
}

I noticed that in my startDialogAuth it sets the AccessToken and AccessExpires

private void startDialogAuth(Activity activity, String[] permissions) {

    Bundle params = new Bundle();
    if (permissions.length > 0) {
        params.putString("scope", TextUtils.join(",", permissions));
    }
    CookieSyncManager.createInstance(activity);
    dialog(activity, LOGIN, params, new DialogListener() {

        public void onComplete(Bundle values) {

            // ensure any cookies set by the dialog are saved
            CookieSyncManager.getInstance().sync();
            setAccessToken(values.getString(TOKEN));
            setAccessExpiresIn(values.getString(EXPIRES));
            if (isSessionValid()) {
                Util.logd("Facebook-authorize", "Login Success! access_token="
                        + getAccessToken() + " expires="
                        + getAccessExpires());

                mAuthDialogListener.onComplete(values);
            } else {
                mAuthDialogListener.onFacebookError(new FacebookError(
                                "Failed to receive access token."));
            }
        }

        public void onError(DialogError error) {
            Util.logd("Facebook-authorize", "Login failed: " + error);
            mAuthDialogListener.onError(error);
        }

        public void onFacebookError(FacebookError error) {
            Util.logd("Facebook-authorize", "Login failed: " + error);
            mAuthDialogListener.onFacebookError(error);
        }

        public void onCancel() {
            Util.logd("Facebook-authorize", "Login canceled");
            mAuthDialogListener.onCancel();
        }
    });
}

And in the startSingleSignOn it looks like this

private boolean startSingleSignOn(Activity activity, String applicationId,
        String[] permissions, int activityCode) {
    boolean didSucceed = true;
    Intent intent = new Intent();

    intent.setClassName("com.facebook.katana",
            "com.facebook.katana.ProxyAuth");
    intent.putExtra("client_id", applicationId);

    if (permissions.length > 0) {
        intent.putExtra("scope", TextUtils.join(",", permissions));
    }

    // Verify that the application whose package name is
    // com.facebook.katana.ProxyAuth
    // has the expected FB app signature.
    if (!validateActivityIntent(activity, intent)) {
        return false;
    }

    mAuthActivity = activity;
    mAuthPermissions = permissions;
    mAuthActivityCode = activityCode;

    try {
        activity.startActivityForResult(intent, activityCode);
    } catch (ActivityNotFoundException e) {
        didSucceed = false;
    }

    return didSucceed;
}

I'm wondering where it sets the Access Token that is needed when logs-in, I'm facing the problem where the user has a Facebook app installed and already authorized my app, it will only show a dialog (Loading) and display a white screen then dismiss but nothing happen next. It doesn't get the user's information from the logged Facebook app. But when the user doesn't have a Facebook app it displays the WebView and just working fine, it logs in correctly. While debugging it I also notice that it doesn't go inside my function LoginDialogListener here it implements Facebook.DialogListener (when there is facebook app installed) maybe because in startSingleSignOn it doesn't call CookieSyncManager.createInstance(activity); dialog(activity, LOGIN, params, new DialogListener() {

here's my activity code where it calls the facebook.authorize

public void setFacebookConnection() {
    facebook = new Facebook(Constants.FACEBOOK_APP_ID);
    facebookAsyncRunner = new AsyncFacebookRunner(facebook);

    facebook.authorize(this, Constants.FACEBOOK_PERMISSIONS, new LoginDialogListener());
}

private class LoginDialogListener implements Facebook.DialogListener {
    public void onComplete(Bundle values) {
        Log.d(TAG, "LoginONComplete");
        String token = facebook.getAccessToken();
        long token_expires = facebook.getAccessExpires();
        Log.d(TAG, "AccessToken: " + token);
        Log.d(TAG, "AccessExpires: " + token_expires);

        if (isPublishStreamAuthorized()) {
            facebookSharedPreferences = PreferenceManager
                    .getDefaultSharedPreferences(context);
            facebookSharedPreferences
                    .edit()
                    .putLong(Constants.FACEBOOK_ACCESS_EXPIRES,
                            token_expires).commit();
            facebookSharedPreferences.edit()
                    .putString(Constants.FACEBOOK_ACCESS_TOKEN, token)
                    .commit();
            facebookAsyncRunner.request("me", new IDRequestListener());
        } else {
            logoutFacebook();
        }

    }

    public void onFacebookError(FacebookError e) {
        Log.d(TAG, "FacebookError: " + e.getMessage());
    }

    public void onError(DialogError e) {
        Log.d(TAG, "Error: " + e.getMessage());
        Toast.makeText(getApplicationContext(), Constants.NO_INTERNET_CONNECTION,
                Toast.LENGTH_LONG).show();
    }

    public void onCancel() {
        Log.d(TAG, "OnCancel");
        logoutFacebook();
    }

}

It seems that my facebook.getAccessToken(); in my activity returns null, as tried calling in my setFacebookConnection() after calling facebook.authorize()

Can you please help me? I needed to solve this soon. Thank you so much.

Update

I found this and tried doing step 3 but it ends up opening the WebView again.

***Update

I finally get the access token, by calling onActivityResult() but the get data will only show after I close the app and open it again here is my code where FACEBOOK_AUTH_RESULT_CODE value I changed it to 32665.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == Constants.FACEBOOK_AUTH_RESULT_CODE) {
        facebook.authorizeCallback(requestCode, resultCode, data);
    } else {
        Log.e(TAG, "onActivityResult Error : Authentication Error");
    }
} 

Answer 1

1)You don't need to use 'provider' tag.

2) com.facebook.FacebookActivity is Facebook's own activity, FacebookLoginActivity - yours.

3)Just use this code to get gender, locale, verified, email:

    GraphRequest request = GraphRequest.newMeRequest(
        AccessToken.getCurrentAccessToken(),
        new GraphRequest.GraphJSONObjectCallback() {
            @Override
            public void onCompleted(
                    JSONObject object,
                    GraphResponse response) {
            }
        });
    Bundle parameters = new Bundle();
    parameters.putString("fields", "id,name,gender,verified,locale,email");
    request.setParameters(parameters);
    request.executeAsync();

4) Could you please share your class. I need more information about "Unexpected call to LoginManager.onActivityResult"

Answer 2

gradle:

compile 'com.facebook.android:facebook-android-sdk:[4,5)'

strings.xml

<string name="facebook_app_id">YOUR_APP_ID</string>

AndroidManifest.xml Add inside of 'application' tag:

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

Create this to init FacebookSDK:

public class MainApp extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        FacebookSdk.sdkInitialize(getApplicationContext());
    }
}

Add it to AndroidManifest.xml to 'application' tag as the name:

<application
    android:name=".MainApp"

In your activity layout add Facebook Login Button:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.app.FacebookLoginActivity">

 <com.facebook.login.widget.LoginButton
        android:id="@+id/login_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="30dp"
        android:layout_marginBottom="30dp" />

</RelativeLayout>

Your FacebookLoginActivity: And Here you can get now your Facebook Token.

public class FacebookLoginActivity extends AppCompatActivity{

private CallbackManager callbackManager;
private LoginButton loginButton;
private String FB_TOKEN;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_signin);
    callbackManager = CallbackManager.Factory.create();
    loginButton = (LoginButton) findViewById(R.id.login_button);
    loginButton.setReadPermissions("public_profile", "user_friends", "email", "user_birthday");
    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {

            /**
             * HERE YOU CAN GET YOUR FACEBOOK TOKEN!!!!
             **/
            FB_TOKEN=loginResult.getAccessToken().getToken();
        }

        @Override
        public void onCancel() {
        }

        @Override
        public void onError(FacebookException exception) {
        }
    });
}

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

}

If you need to use Custom Facebook Button:

public class FacebookLoginActivity extends AppCompatActivity{

private CallbackManager callbackManager;
private Button loginButton;
private String FB_TOKEN;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_signin);
    callbackManager = CallbackManager.Factory.create();
    loginButton = (Button) findViewById(R.id.login_button);
    LoginManager.getInstance().registerCallback(callbackManager,
            new FacebookCallback<LoginResult>() {
                @Override
                public void onSuccess(LoginResult loginResult) {
                    /**
                    * HERE YOU CAN GET YOUR FACEBOOK TOKEN!!!!
                    **/
                    FB_TOKEN=loginResult.getAccessToken().getToken();
                }

                @Override
                public void onCancel() {
                }

                @Override
                public void onError(FacebookException exception) {
                    Log.e("onError", exception.getMessage());
                }
            });
    loginButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                LoginManager.getInstance().logInWithReadPermissions(FacebookLoginActivity.this, Arrays.asList("public_profile", "user_friends", "email"));
            }
    });
}

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

}
