问题
I'm trying to create a user in the Firebase console using email and password but it doesn't work showing an error.
Actually we can add users in the console by going to the dashboard and clicking on add user but I want to automate this process.
Here's the full code:
import android.content.Intent;
import android.os.Bundle;
import android.preference.PreferenceManager;
import android.support.annotation.NonNull;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;

private Button but;
private EditText email;

String user_id="",pass="";
@Override

but.setOnClickListener(new View.OnClickListener() {
@Override

}
@Override

});
}
});
mSignInButton = (SignInButton) findViewById(R.id.sign_in_button);
mSignInButton.setOnClickListener(this);

.enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
// Initialize FirebaseAuth
mFirebaseAuth = FirebaseAuth.getInstance();
}
private void handleFirebaseAuthResult(AuthResult authResult) {
if (authResult != null) {
FirebaseUser user = authResult.getUser();
Toast.makeText(this, "Welcome " + user.getEmail(), Toast.LENGTH_SHORT).show();
startActivity(new Intent(this, MainActivity.class));
}
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.sign_in_button:
signIn();
break;
default:
return;
}
}
private void signIn() {
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(signInIntent, RC_SIGN_IN);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RC_SIGN_IN) {
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
if (result.isSuccess()) {
GoogleSignInAccount account = result.getSignInAccount();
firebaseAuthWithGoogle(account);
Log.e(TAG, "Google Sign In Successfull.");
} else {
Log.e(TAG, "Google Sign In failed.");
}
}
}
private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
Log.d(TAG, "firebaseAuthWithGooogle:" + acct.getId());
AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
mFirebaseAuth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override

Log.d(TAG, "signInWithCredential:onComplete:" + task.isSuccessful());

Log.w(TAG, "signInWithCredential", task.getException());
Toast.makeText(SignInActivity.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
} else {

finish();
try {
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
});
}
@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
Log.d(TAG, "onConnectionFailed:" + connectionResult);
Toast.makeText(this, "Google Play Services error.", Toast.LENGTH_SHORT).show();
}
}
}
The code used to create an user is :
but.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
user_id= email.getText().toString();
pass= password.getText().toString();
Firebase ref = new Firebase("https://final-6b828.firebaseio.com/auth");
ref.createUser(user_id, pass, new Firebase.ValueResultHandler<Map<String, Object>>() {
@Override
public void onSuccess(Map<String, Object> result) {
System.out.println("Successfully created user account with uid: " + result.get("uid"));
String a= result.get("uid").toString();
Log.i("Success",user_id);
Log.i("Success",pass);
Toast.makeText(getApplicationContext(), "Pass",
Toast.LENGTH_LONG).show();
}
@Override
public void onError(FirebaseError firebaseError) {
// there was an error
System.out.println("Failed to create user account : ");
Log.i("Failed","a");
Toast.makeText(getApplicationContext(), "Failed",
Toast.LENGTH_LONG).show();
}
});
}
});

The correct code to create a user is..
but.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
user_id= email.getText().toString();
pass= password.getText().toString();
createAccount(user_id,pass);
}
});
private void createAccount(String email, String password) {
Log.d(TAG, "createAccount:" + email);
if (!validateForm()) {
return;
}
// showProgressDialog();
// [START create_user_with_email]
mAuth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
Log.d(TAG, "createUserWithEmail:onComplete:" + task.isSuccessful());
// If sign in fails, display a message to the user. If sign in succeeds
// the auth state listener will be notified and logic to handle the
// signed in user can be handled in the listener.
if (!task.isSuccessful()) {
Toast.makeText(SignInActivity.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
}
// [START_EXCLUDE]
//hideProgressDialog();
// [END_EXCLUDE]
}
});
// [END create_user_with_email]
}
private boolean validateForm() {
boolean valid = true;
String emails = email.getText().toString();
if (TextUtils.isEmpty(emails)) {
email.setError("Required.");
valid = false;
} else {
email.setError(null);
}
String passwords = password.getText().toString();
if (TextUtils.isEmpty(passwords)) {
password.setError("Required.");
valid = false;
} else {
password.setError(null);
}
return valid;
}
