I have the following class that I instantiate from my fragment:
public class FacebookLogin {
private CallbackManager mCallbackManager;
private LoginButton lButton;
private AccessToken accessToken;
private Profile profile;
private static final String TAG = "FacbookLogin";
public FacebookLogin(Context c) {
FacebookSdk.sdkInitialize(c);
mCallbackManager = CallbackManager.Factory.create();
Log.i(TAG, " Constructor called");
}
private FacebookCallback<LoginResult> mCallback = new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
Log.i(TAG, " logged in...");
AccessToken accessToken = loginResult.getAccessToken();
profile = Profile.getCurrentProfile(); //Access the profile who Is the person login i
}
#Override
public void onCancel() {
}
#Override
public void onError(FacebookException e) {
Log.i(TAG, " Error");
Log.e(TAG, e.getMessage());
}
};
public void setCallback(LoginButton lButton) {
lButton = lButton;
lButton.registerCallback(mCallbackManager, mCallback);
Log.i(TAG, " setCallback called");
}
And here Is my fragment-class:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
fLogin = new FacebookLogin(getActivity().getApplicationContext());
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.login, container, false);
return v;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState)
{
super.onViewCreated(view, savedInstanceState);
final LoginButton loginButton = (LoginButton) getView().findViewById(R.id.login_button);
final TextView infoText = (TextView) getView().findViewById(R.id.text_details);
loginButton.setFragment(this);
loginButton.setReadPermissions("user_friends");
loginButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Log.i(TAG, " Button clickde");
fLogin.setCallback(loginButton); //Let's register a callback
profile = fLogin.getProfile();
if (profile != null) {
Log.i(TAG, profile.getName()); //Call this after the callback request Is finished
} else {
Log.i(TAG, "NULL....... inside onresume");
}
}
});
}
I want to call profile = fLogin.getProfile(); after the callback request is complete. But I don't know how to do this. I have read about the onComplete();, but I don't know how to Implement It here.

I'm getting nullPointerException when I try to set data to textviews from the JSON response,I'm getting through retrofit. I would like to set the total sale, total expense and total purchase values to the textviews:
tv_total_purchase_today,
tv_total_sale_today,
tv_total_expense_today
What should I put in the setsaleInformations method?
Here's my code:

public class DashboardResponse extends CommonResponse {

#Expose
#SerializedName("total_expense")
private String total_expense;
public ArrayList<Graph> getGraph_data() {
return graph_data;
}
public void setGraph_data(ArrayList<Graph> graph_data) {
this.graph_data = graph_data;
}
public String getTotal_sale() {
return total_sale;
}
public void setTotal_sale(String total_sale) {
this.total_sale = total_sale;
}
public String getTotal_purchase() {

That means either the text views haven't loaded onto the screen yet or the views haven't been initialized yet.

If you are trying to start an activity as soon as the user successfully logs in, you can call startActivity(intent) in the onSuccess(LoginResult loginResult) method of the FacebookCallback.
try this in onSuccess method
GraphRequest request = GraphRequest.newMeRequest(
accessToken,
new GraphRequest.GraphJSONObjectCallback() {
#Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
// Application code
try {
String name = object.getString("name");
String id = object.getString("id");
Intent redirect=new Intent(Login_Activity.this,anotheractivity.class);
startActivity(redirect);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
My issue is very simple, I want users to login using Facebook. After a successful login, grab some details and pass it on another activity. I have my new class in manifeset. I see the log for Log.v("facebook - profile", profile.getFirstName()); I'm quite baffled about what's going on. I have no errors either. I'm passing my activity in the onSuccess.
public class MainActivityFragment extends Fragment {
TextView textview;
private AccessTokenTracker tokenTracker;
private ProfileTracker profileTracker;
private CallbackManager mCallbackManager;
private FacebookCallback<LoginResult> mCallback = new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
AccessToken accessToken = loginResult.getAccessToken();
if(Profile.getCurrentProfile() == null) {
profileTracker = new ProfileTracker() {
#Override
protected void onCurrentProfileChanged(Profile profile, Profile profile2) {
Log.v("facebook - profile", profile2.getFirstName());
profileTracker.stopTracking();
}
};
profileTracker.startTracking();
}
else {
Profile profile = Profile.getCurrentProfile();
Log.v("facebook - profile", profile.getFirstName());
//get info to pass to next activity
String[] profileDetailsArray = new String [5];
profileDetailsArray[0] = profile.getFirstName();
profileDetailsArray[1] = profile.getLastName();
profileDetailsArray[2] = profile.getId();
Bundle arrayBundle = new Bundle();
arrayBundle.putStringArray("profileDetails",profileDetailsArray);
Intent intent = new Intent(getActivity(),LandingPage.class);
intent.putExtras(arrayBundle);
startActivity(intent);
}
}
#Override
public void onCancel() {
}
#Override
public void onError(FacebookException e) {
}
};
public MainActivityFragment() {
}
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
mCallbackManager = CallbackManager.Factory.create();
AccessTokenTracker tokenTracker = new AccessTokenTracker() {
#Override
protected void onCurrentAccessTokenChanged(AccessToken oldToken, AccessToken newToken) {
}
};
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_main, container, false);
}
#Override

super.onViewCreated(view, savedInstanceState);
LoginButton loginButton = (LoginButton) view.findViewById(R.id.login_button);
loginButton.setReadPermissions(Arrays.asList("user_location", "user_birthday", "public_profile"));
loginButton.setFragment(this);
loginButton.registerCallback(mCallbackManager,mCallback);

How and Where do I set view contents to be displayed for persons who has successfully been authenticated using Facebook SDK?
After the persons has logged In, I want to display a User profile view.
I have tried to Instansiate a new fragment like the code below, but that don't work. The text "Fish" Is not displayed.
public class LoginFragment extends Fragment {
private CallbackManager mCallbackManager;
private static final String TAG = "Facebook";
private LoginButton login;
private FacebookCallback<LoginResult> mCallback = new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
Log.i(TAG, " logged in...");
AccessToken accessToken = loginResult.getAccessToken();
Profile profile = Profile.getCurrentProfile(); //Access the profile who Is the person login in
if(profile != null) {
FragmentManager fm = getFragmentManager();
Fragment fragment = fm.findFragmentById(R.id.fragmentContainer);
if(fragment == null) {
fragment = new LoggedInFragment();
fm.beginTransaction().add(R.id.fragmentContainer, fragment).commit();
}
}
}
#Override
public void onCancel() {
}
#Override
public void onError(FacebookException e) {
Log.i(TAG, " Error");
}
};
public LoginFragment() {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
mCallbackManager = CallbackManager.Factory.create();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.login, container, false);
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
LoginButton loginButton = (LoginButton) view.findViewById(R.id.login_button);
//Ask the use for permission to access friends
loginButton.setReadPermissions("user_friends");
//Because we work with fragments
loginButton.setFragment(this);
loginButton.registerCallback(mCallbackManager, mCallback);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
mCallbackManager.onActivityResult(requestCode, resultCode, data);
}
}
Here IS fragement that the user should see when he/she Is logged In:
package com.waddapp.bryan.waddapp;
public class LoggedInFragment extends Fragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.logged_in, container, false);
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
TextView mTextDetails = (TextView)view.findViewById(R.id.text_details);
mTextDetails.setText("FISH");
}
public LoggedInFragment() {
}
}
Anyone who can explain how acomplish this?
I want to know if there's a way to get and pass FBUSER and FBID to each of my tab bars, and use them in every web view by passing them in the url, because I need to use them in my web views.

I know that simply getting these variables can be quite tricky because they're always nested in callback methods.
What I do is store them in SharedPreferences, and then I get them easily in another part of the app.
To write more elegant and more importantly safe/efficient code, you can look up event bus (like Otto, EventBus) or Observables (RxJava) which can handle sending these objects asynchronously very easily !
Hope I helped you :).
