I am using firebase facebook login for my application when user login from facebook for the very first time it creates account and let user login but after logging user out or if i delete app data and login again it gives error log.
fbauth = FirebaseAuth.getInstance();
final LoginButton loginButton = (LoginButton) findViewById(R.id.fbsignup_button);
loginButton.setReadPermissions("email","public_profile");
mAuthListener = new FirebaseAuth.AuthStateListener() {
@Override
public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
FirebaseUser user = firebaseAuth.getCurrentUser();
if (user != null) {
Intent intent = new Intent(SignupActivity.this, BaseActivity.class);
startActivity(intent);
// User is signed in
Log.d("", "onAuthStateChanged:signed_in:" + user.getUid());
} else {
// User is signed out
Log.d("", "onAuthStateChanged:signed_out");
}
}
};
loginButton.registerCallback(mCallbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
Log.d("FacebookAuthresult", "facebook:onSuccess:" + loginResult);
handleFacebookAccessToken(loginResult.getAccessToken());
}
@Override
public void onCancel() {
Log.d("FacebookAuthresult", "facebook:onCancel");
// ...
}
@Override
public void onError(FacebookException error) {
Log.d("FacebookAuthresult", "facebook:onError", error);
// ...
}
});
private void handleFacebookAccessToken(AccessToken token) {
Log.d("FacebookAuthresult", "handleFacebookAccessToken:" + token);
AuthCredential credential = FacebookAuthProvider.getCredential(token.getToken());
fbauth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
Log.d("FacebookAuthresult", "signInWithCredential:onComplete:" + task.isSuccessful());
if (task.isSuccessful()) {
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
appsettings appData = new appsettings();
if(user.getEmail()!= null)
appData.setEmailofuser(user.getEmail());
if(user.getDisplayName() != null)
appData.setUsername(user.getDisplayName());
if(user.getPhotoUrl() != null) {
appData.setUriofphoto(user.getPhotoUrl());
Log.v("FBReturnedphoto", user.getPhotoUrl().toString());
appData.savePreference(getApplicationContext());
}
Intent intent = new Intent(SignupActivity.this, BaseActivity.class);
startActivity(intent);
}
else {
Log.w("FacebookAuthresult", "signInWithCredential", task.getException());
Toast.makeText(SignupActivity.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
}
// ...
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
mCallbackManager.onActivityResult(requestCode, resultCode, data);
}
And if i delete user info from firebase console and delete app from facebook app settings it works fine again for the first time only and after signing user out same problem occurs again."
