I created register activity with Firebase Authorization, and trying to register new user, but when I press register button I got exception from my code
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
etUsername = (EditText) findViewById(R.id.etUserName);
etEmail = (EditText) findViewById(R.id.etEmailRegiter);
etPassword = (EditText) findViewById(R.id.etPasswordRegiter);
etPasswordRe = (EditText) findViewById(R.id.etPasswordRegiterRe);
register = (Button) findViewById(R.id.btnRegister);
passwordRule = (LinearLayout) findViewById(R.id.password_rule);
etPassword.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
passwordRule.setVisibility(View.VISIBLE);
}
});
mAuth = FirebaseAuth.getInstance();
register.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
createAccount(etUsername.getText().toString(), etPassword.getText().toString());
}
});
}
private void createAccount(String email, String password) {
Log.d(LOG_TAG, "createAccount:" + email);
// if (!validateForm()) {
// return;
// }
mAuth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Log.d(LOG_TAG, "createUserWithEmail:success");
FirebaseUser user = mAuth.getCurrentUser();
Log.d(LOG_TAG, ":" + mDatabase.child(PATH_TO_DATA_USERS));
// sendEmailVerification();
// Intent intent = new Intent(getContext(), MainActivity.class);
// intent.putExtra("user", user.getUid());
// startActivity(intent);
}
else {
try {
throw task.getException();
} catch(FirebaseAuthWeakPasswordException e) {
etPassword.setError("weak password");
etPassword.requestFocus();
} catch(FirebaseAuthInvalidCredentialsException e) {
etEmail.setError("invalid credential exception");
etEmail.requestFocus();
} catch(FirebaseAuthUserCollisionException e) {
etEmail.setError("collision exception");
etEmail.requestFocus();
} catch(Exception e) {
Log.e(LOG_TAG, e.getMessage());
}
Log.w(LOG_TAG, "createUserWithEmail:failure", task.getException());
Log.d(LOG_TAG, ":" + (mAuth == null));
Toast.makeText(RegisterActivity.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
}
}
});
}

(Here in my code task.isSuccessful() returns me false and for to solve this problem i commented my validation method. So now no validation for password and email, but before I tried to run code with validation, which returns me same error)
and in logs get error like this
E/Volley: [187] BasicNetwork.performRequest: Unexpected response code 400 for https://www.googleapis.com/identitytoolkit/v3/relyingparty/signupNewUser?key=AIzaSyAPBVdM4hZpPBvTZrvE9gBjld0otb202Lg
I/AuthChimeraService: Error description received from server: {
"error": {
"errors": [
{
"domain": "global",
"reason": "invalid",
"message": "INVALID_EMAIL"
}
],
"code": 400,
"message": "INVALID_EMAIL"
}
}
By the way I tried to sign up by creation new user by myself through console. It works well I can sign with this user.
Here is my gradle dependencies
compile 'com.google.firebase:firebase-database:10.0.1'
compile 'com.google.firebase:firebase-core:10.0.1'
compile 'com.google.firebase:firebase-auth:10.0.1'
回答1:
Probably the email user put in is not valid. Emails should be in this format = "myname@domain.com". If it does not match the format, that error is given by the server. Try putting in an email in that format. I will recommend you to read more about authentication here: https://firebase.google.com/docs/auth/custom-email-handler and here is a bit more about the firebase error codes: https://firebase.google.com/docs/reference/js/firebase.auth.Auth
EDIT:
You are sending "Username" to the email variable not the "Email"
Here is the code you need to fix: createAccount(etUsername.getText().toString(), etPassword.getText().toString());
You are sending username in the place of email so thats why the server is calling your email invalid. Change it to etEmail.
Remember, when you are registering, you are registering with the Email not the Username!

I'm starting using Firebase too, I'm using this code to register new users in my app and works well.
public void doRegister(final String username, String password) {
HideAppApplication.mAuth.createUserWithEmailAndPassword(username, password)
.addOnCompleteListener(activity, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
Log.d("LOGIN", "createUserWithEmail:onComplete:" + task.isSuccessful());
if (task.isSuccessful()){
User user = new User();
user.setUserId(username);
DatabaseReference mDatabase = FirebaseDatabase.getInstance().getReference().child("user");
mDatabase.child(task.getResult().getUser().getUid()).setValue(user);
}
onRegisterRequested.registerRequested(task);
}
});
}
You can take a look to my project in github if you want.
Hope this can solve your problem.
