The following code is what I ended up with after going through some solutions. I would like to thank @marialena and @mziemer for their detailed solutions.
//facebook button click
pbLogin.setVisibility(View.VISIBLE);
ParseFacebookUtils.logInWithReadPermissionsInBackground(this, permissions, new LogInCallback() {
@Override
public void done(final ParseUser user, ParseException err) {
if (user == null) {
Log.d(TAG, "The user cancelled the Facebook login.");
Toast.makeText(getApplicationContext(), "Logout from Facebook and try again.", Toast.LENGTH_SHORT).show();
ParseUser.logOut();
pbLogin.setVisibility(View.GONE);
} else if (user.isNew()) {
Log.d(TAG, "User signed up and logged in through Facebook!");
getFacebookUserDetails(true, user, err);
} else {
getFacebookUserDetails(false, user, err);
}
}
});
public void getFacebookUserDetails(final boolean firstTime, final ParseUser user, final ParseException error) {
GraphRequest request = GraphRequest.newMeRequest(
AccessToken.getCurrentAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
// Application code
try {
userName = object.getString("name");

Bundle parameters = new Bundle();
parameters.putString("fields", "age_range,gender,name,id,link,email,picture.type(large),first_name,last_name");
request.setParameters(parameters);
request.executeAsync();
}
There are few scenarios I still haven't come across from this code. Will update as and when I come across them.
