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");
    }
}

The code you referring is too old. Some of them might be deprecated. Try the official docs and examples https://developers.facebook.com/docs/android/getting-started — Mahendran Sakkarai, Oct 12 '16 at 21:15
@MahendranSakkarai i need to use this to avoid big changes :( — natsumiyu, Oct 13 '16 at 02:38

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);
}

}

Using the above code, can I still check if the facebook app is installed and if not it will open a `WebView` instead? — natsumiyu, Oct 12 '16 at 23:31
@mori Yep sure, i edited my answer. I Added example: how to use Custom Facebook Button. — Rahim Rahimov, Oct 12 '16 at 23:55
Thank you so much @Rahim , also how can i get the `token_expires` ? — natsumiyu, Oct 13 '16 at 00:43
i tried the code using the custom but it doesn't open the facebook app :( — natsumiyu, Oct 13 '16 at 01:22
1) Reinstall your app and try again, 2) Check again your facebook sdk id, 3) Go to developers.facebook.com and check the correctness of written Hash addresses and package name of your app. 4) Here is how to get correct Hash for facebook sdk: http://stackoverflow.com/a/35128380/4576879 — Rahim Rahimov, Oct 13 '16 at 07:15
@mori try loginResult.getAccessToken().getExpires() to get token_expires — Rahim Rahimov, Oct 13 '16 at 07:23
it looks like I need to still used the old `Facebook.java`, I changed the `FACEBOOK_AUTH_RESULT_CODE` to other values and i can get the access token but it crashes after going back to my app. I still don't know the reason why it crashes. — natsumiyu, Oct 13 '16 at 07:28
U should use this one: @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); callbackManager.onActivityResult(requestCode, resultCode, data); } — Rahim Rahimov, Oct 13 '16 at 08:03
is `FacebookLoginActivity` and `com.facebook.FacebookActivity` are different activity? — natsumiyu, Oct 17 '16 at 03:33
I can log-in now but I wonder how can I get the other info like gender, locale, verified and email? — natsumiyu, Oct 17 '16 at 06:29
i tried using the custom button but I'm having error `Unexpected call to LoginManager.onActivityResult` — natsumiyu, Oct 18 '16 at 06:52

Rahim Rahimov · Answer 2 · 2016-10-18T13:14:38.903

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"

I fixed the `Unexpected call to LoginManager.onActivityResult` it is because of the intent I'm calling in my `onActivityResult` Thank you so much for the help! — natsumiyu, Oct 18 '16 at 08:55
@natsumiyu can you post the code please - I have the same issue — Zain, Jan 30 '20 at 09:50
