I have an app that uses Facebook in combination with Parse to login users.
My problem is that when I fully close the application and then open it again, my AccessToken from Facebook is null. Seems like it is not stored from Session to session for some reason.
When I just log out and then in again, it works fine. Anyone experienced the same issue?
This is how I log in the users:
List<String> permissions = Arrays.asList("public_profile");
ParseFacebookUtils.logInWithReadPermissionsInBackground(this, permissions, new LogInCallback() {
#Override
public void done(ParseUser user, ParseException err) {
if (user == null) {
//Error...
} else if (user.isNew()) {
//Some code...
mCurrentUser = ParseUser.getCurrentUser();
} else {
//Some code...
mCurrentUser = ParseUser.getCurrentUser();
}
}
});
add Parse.enableLocalDatastore(this); in onCreate() of your_app extends Application
this is my code which uses Parse to log a user in via Facebook.
public void onFacebookLoginClick(View v) {
ParseUser currentUser = ParseUser.getCurrentUser();
if ((currentUser != null) && ParseFacebookUtils.isLinked(currentUser)) {
Log.d("onFacebookLoginClick", "Already signed in");
showHomeActivity();
} else {
progressDialog = ProgressDialog.show(LoginActivity.this, "", "Logging in...", true);
List<String> permissions = Arrays.asList("public_profile", "email");
// NOTE: for extended permissions, like "user_about_me", your app must be reviewed by the Facebook team
// (https://developers.facebook.com/docs/facebook-login/permissions/)
ParseFacebookUtils.logInWithReadPermissionsInBackground(this, permissions, new LogInCallback() {
#Override
public void done(ParseUser user, ParseException err) {
progressDialog.dismiss();
if (user == null) {
Log.d("Facebook", "Uh oh. The user cancelled the Facebook login.");
} else if (user.isNew()) {
Log.d("onFacebookLoginClick: ", "User signed up and logged in through Facebook!");
showHomeActivity();
} else {
Log.d("onFacebookLoginClick: ", "User logged in through Facebook!");
showHomeActivity();
}
}
});
}
}
The problem is, the user logs in the first time (OK!), then the login dialog opens up again.
Note: When I close the dialog, it does take me to the next activity. But why can it be showing the login dialog twice?
I had a similar issue implementing this. I solved it by letting my code sleep for a few seconds before attempting to start the activity. It's possible this may be the bug.
--Why I arrived at this conclusion--
I found the loginCallBack in ParseFacebookUtils takes a few seconds to return with its result code/parse user.
No data was returned by the time I start the activity and the activity is configured to launch the login activity if no user is logged in. This made it appear as though the code wasn't logging in on first try. I believe the Parse Facebook logic is a little slower than the regular parse login logic.
The second time you run the code (click the button) the callback was already returned with the parse user and would successfully launch the activity without returning.
I use a Parse database. I would like to have access for simple users and an admin user. The would be that each user could see only his/her own data but the admin user could see all of users' data.
I create a ParseUser, and if the current user is equal with it, it should be known it is the admin user.
I get the following error:
java.lang.IllegalArgumentException: cannot setReadAccess for a user with null id
I think the mistakes are with if function (never become true) and this: acl.setReadAccess(ADMIN,true);
Could anyone suggest something?
ParseUser ADMIN = new ParseUser();
ADMIN.setUsername("ADMIN3");
ADMIN.setPassword("a");
// Create a post.
AnywallPost post = new AnywallPost();
// Set the location to the current user's location
post.setLocation(geoPoint);
post.setText(text);
post.setUser(ParseUser.getCurrentUser());
ParseACL acl = new ParseACL();
// Give read accesses
if (ParseUser.getCurrentUser() == ADMIN) {
acl.setReadAccess(ParseUser.getCurrentUser(), true);
}
else
{
acl.setReadAccess(ParseUser.getCurrentUser(),true);
acl.setReadAccess(ADMIN,true);
}
post.setACL(acl);
// Save the post
post.saveInBackground(new SaveCallback() {
#Override
public void done(ParseException e) {
dialog.dismiss();
finish();
}
});
I've been using Parse for 3 months in my android app. Now I want to add email login and social sign ons (Facebook and Google+) in the app. I have successfully added email and fb login and the user can connect both or either one of email or facebook and the app would recognise the user.
e.g. If I login through email, then connect facebook, use the app on another device, login via facebook, the app would know it's the same user and would be customised for me and would show my data. And email also works.
I have added Google+ sign-in for Android but I am not able to connect the user's Google+ credentials with the logged in user.
Parse Users table has an authData field which gets the facebook auth data and would get Twitter as well as both of these sign ons are baked into Parse SDKs.
What should be the best thing to do for Google+? I'm confused about the db design as well as how to connect the user who signed in with Google+?
What if the user just logs in via Google+? How do I make a Parse User and authenticate the user on Parse?
I'm comfortable with cloud code and Android and would really appreciate some sort of help/instructions just pushing me in the correct direction. I have never used OAuth2 and with Parse login for email and Social Sign ons, I don't think I should get into it. But let me know if I'm wrong.
Thanks!
Update: I have read a lot of questions on Parse Questions and have checked out the become method plenty of times (because I kept thinking I'm missing something after reading that). Check this question - I'm currently in the same situation.
I have:
1. Implemented Google+ sign in.
2. Got access token using GoogltAuthUtil.
Stuck with:
3. How to link currently signed in Parse user after the user signs in with Google+?
4. How to create a new Parse User if Google+ was the user's first (and only ) login choice?
This seems to be similar with
How to create a parse _User account from a Android Google token?
Following is my answer in that thread:
1. New User
The flow is as below:
User authorizes and a token is acquired
We create a new user with a random password
You can create a ParseUser using following code inside the newChooseAccountIntent() method that return email.
ParseUser user = new ParseUser();
user.setUsername(mEmail);
user.setPassword(randomPassword);
user.setEmail(mEmail);
user.signUpInBackground(new SignUpCallback() {
public void done(ParseException e) {
if (e == null) {
// Hooray! Let them use the app now.
} else {
// Sign up didn't succeed. Look at the ParseException
// to figure out what went wrong
}
}
});
2. Returning User
This is the where most of people stuck, as I researched over the Internet. The flow is as below:
User authorizes and the app gets a token
We pass this token to Cloud Code to validate. We need to check if this token is signed by Google and if it is meant for us (android-developers (2013)).
After you can verify that the token is valid, you can query for the user in Cloud Code using Parse.Cloud.useMasterKey() method and return the session key by using getSessionToken() method on the query result.
Use the session key to save login state on disk by calling becomeInBackground method
To validate the token, you can send Parse.Cloud.httprequest to this endpoint: https://www.googleapis.com/oauth2/v3/tokeninfo?access_token=. This is instructed in Google Identity Documentation. You will receive data as below:
{
"iss": "https://accounts.google.com",
"sub": "110169484474386276334",
"azp": "1008719970978-hb24n2dstb40o45d4feuo2ukqmcc6381.apps.googleusercontent.com",
"email": "billd1600#gmail.com",
"at_hash": "X_B3Z3Fi4udZ2mf75RWo3w",
"email_verified": "true",
"aud": "1008719970978-hb24n2dstb40o45d4feuo2ukqmcc6381.apps.googleusercontent.com",
"iat": "1433978353",
"exp": "1433981953"
}
Things need to compare are "aud", "azp" and "email" which are translated as audience, authorized party and email.
To query for the current user on Cloud Code:
var query = new Parse.Query(Parse.User);
query.equalTo("email",mEmail);
query.first({
success: function(user) {
// Use user..getSessionToken() to get a session token
},
error: function(user, error) {
//
},
useMasterKey: true
});
Note: Make sure you have following scope so that the email will show up when you check on Cloud Code: https://www.googleapis.com/auth/plus.profile.emails.read
There's a question about this on Parse's questions. It's right here and I'm pretty sure it answers your questions.
https://parse.com/questions/google-plus
It links to the parse blog, that has some workarounds on this.
It says that you can add any login into ParseUser. You would be doing something like this:
Parse.User.become("session-token-here").then(function (user) {
// The current user is now set to user.
}, function (error) {
// The token could not be validated.
});
Another site where you should take a look:
https://parse.com/tutorials/adding-third-party-authentication-to-your-web-app
This last one is official and has an example code
void createNewGPlusUser(final String email, String name) {
final ParseUser user = new ParseUser();
user.setUsername(email);
user.setPassword("my pass");
user.put("any other variable in User class", "value");
user.setEmail(email);
user.put("name", name);
signInParseUser(user, email);
}
void signInParseUser(final ParseUser user, final String email) {
user.signUpInBackground(new SignUpCallback() {
public void done(ParseException e) {
if (e == null) {
Log.d("TAG", "Created user");
// Hooray! Let them use the app now.
login(email);
} else {
Log.d("TAG", "Failed Creating user");
e.printStackTrace();
// Sign up didn't succeed. Look at the ParseException
// to figure out what went wrong
}
}
});
}
void login(final String email) {
ParseUser.logInInBackground(email, "my pass", new LogInCallback() {
public void done(ParseUser user, ParseException e) {
if (user != null) {
// Hooray! The user is logged in.
Log.d("TAG", "Login successful");
} else {
// Signup failed. Look at the ParseException to see what happened.
}
}
});
}
To do so, I have used the following code
ParseUser.becomeInBackground(ParseUser.getCurrentUser().getSessionToken(), new LogInCallback() {
#Override
public void done(ParseUser parseUser, ParseException e) {
if (parseUser != null) {
parseUser.setUsername(userEmail);
//firstName and lastName I am getting from Person class of google plus api
parseUser.put("FirstName", firstName);
parseUser.put("LastName", lastName);
parseUser.saveInBackground();
ParseUtils.verifyParseConfiguration(context);
ParseUtils.subscribeWithUsername(strEmail);
Intent successIntent = new Intent(context, OurServicesActivity.class);
startActivity(successIntent);
overridePendingTransition(R.animator.fade_in, R.animator.fade_out);
finish();
} else {
Log.e(TAG, e.getMessage());
Utilities.showToast(context, "Something occurred");
}
}
});
Let me know if it helps or if you have used something else.
Try this
ParseUser.becomeInBackground("session-token-here", new LogInCallback() {
public void done(ParseUser user, ParseException e) {
if (user != null) {
// The current user is now set to user.
} else {
// The token could not be validated.
}
}
})
I'm trying to link an existing user to his or her Facebook account using Parse. After logging into through Parse, the user can go to the SettingsActivity and link their Facebook account.
I achieved this by calling ParseUser.logInInBackground and then verified it by checking if ParseUser.getCurrentUser() != null.
In my SettingsActivity, the user can press a 'Connect to Facebook' button, which is supposed to link the account to Facebook, but it's not working. When the user clicks the button, I executed this code below, as per the Parse Android documentation:
mUser = ParseUser.getCurrentUser();
public void onToggleFacebookConnectedClick(View v) {
if (!ParseFacebookUtils.isLinked(mUser)) {
ParseFacebookUtils.link(mUser, this, new SaveCallback() {
#Override
public void done(ParseException ex) {
if (ParseFacebookUtils.isLinked(mUser)) {
Log.d(Application.APPTAG, "Woohoo, user logged in with Facebook!");
}
}
});
} else if(ParseFacebookUtils.isLinked(mUser)) {
ParseFacebookUtils.unlinkInBackground(mUser, new SaveCallback(){
#Override
public void done(ParseException ex) {
if (ex == null) {
Log.d(Application.APPTAG, "The user is no longer associated with their Facebook account.");
}
}
});
}
}
I am getting the error: com.parse.ParseException:java.lang.IllegalArgumentException: Cannot save a ParseUser until it has been signed up. Call SignUp first.
The user has already signed up (not using Facebook), so I am confused as to why I'm am getting this message. How can I resolve this issue?
It turns out I made a silly mistake. I wasn't linking the user correctly because my Facebook Application ID was not set correctly in my Parse App Settings.
