authentication problem in fire base using android studio
问题
我正在进行一个项目，需要使用 Firebase 实用工具，所以我已经完成了所有必需的事情，但是我的身份验证没有进行，因此我的数据没有被上传到 Firestore 中。我尝试了很多方法，并发现在执行期间，我的 onComplete 监听器调用失败，因此会弹出一个消息框显示身份验证失败，所以我认为主要问题在于 onComplete 监听器，但我无法解决它。我的代码如下：
private TextView username;
private TextView password;
private AutoCompleteTextView email;
private ProgressBar progress_bar;
private FirebaseAuth firebaseAuth;
private FirebaseAuth.AuthStateListener authStateListener;
private FirebaseUser currentUser;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
username = findViewById(R.id.username_account);
password = findViewById(R.id.password_account);
email = findViewById(R.id.email_account);
Button create_account = findViewById(R.id.create_acct_button);
progress_bar = findViewById(R.id.create_acct_progress);
firebaseAuth = FirebaseAuth.getInstance();
create_account.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (!TextUtils.isEmpty(email.getText().toString())
&& !TextUtils.isEmpty(password.getText().toString())
&& !TextUtils.isEmpty(username.getText().toString())) {
String Email = email.getText().toString().trim();
String Password = password.getText().toString().trim();
String Username = username.getText().toString().trim();
createUserEmailAccount(Email, Password, Username);
} else {
Toast.makeText(CreateAccountActivity.this,
"Empty Fields Not Allowed",
Toast.LENGTH_LONG)
.show();
}
}
});
}
private void createUserEmailAccount(String email, String password, final String username) {
if (!TextUtils.isEmpty(email) && !TextUtils.isEmpty(password) && !TextUtils.isEmpty(username)) {
progress_bar.setVisibility((View.VISIBLE));
firebaseAuth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(CreateAccountActivity.this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Map<String, Object> userobj = new HashMap<>();
userobj.put("userId", "currentuserId");
userobj.put("username", username);
db.collection("journal")
.add(userobj)
.addOnSuccessListener(new OnSuccessListener<DocumentReference>() {
@Override
public void onSuccess(DocumentReference documentReference) {
Log.d(TAG, "DocumentSnapshot successfully written!");
progress_bar.setVisibility(View.INVISIBLE);
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Log.w(TAG, "Error writing document", e);
}
});
} else {
Log.w(TAG, "createUserWithEmail:failure", task.getException());
Toast.makeText(CreateAccountActivity.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
progress_bar.setVisibility(View.INVISIBLE);
}
}
});
}
}

I am working on a project which required firebase utilities so I did all those things required but my authentication is not taking place and thereby my data is not being uploaded in the firestore. I have tried many things and found that during the time of execution my onComplete listener is calling failure and thus a toast is popped authentication failure so I think the main problem lies in the onComplete listener but I couldn't fix it. My code is as follows-
*
private TextView username;
private TextView password;
private AutoCompleteTextView email;
private ProgressBar progress_bar;
private FirebaseAuth firebaseAuth;
private FirebaseAuth.AuthStateListener authStateListener;
private FirebaseUser currentUser;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
username = findViewById(R.id.username_account);
password = findViewById(R.id.password_account);
email = findViewById(R.id.email_account);
Button create_account = findViewById(R.id.create_acct_button);
progress_bar = findViewById(R.id.create_acct_progress);
firebaseAuth = FirebaseAuth.getInstance();
create_account.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (!TextUtils.isEmpty(email.getText().toString())
&& !TextUtils.isEmpty(password.getText().toString())
&& !TextUtils.isEmpty(username.getText().toString())) {
String Email = email.getText().toString().trim();
String Password = password.getText().toString().trim();
String Username = username.getText().toString().trim();
createUserEmailAccount(Email, Password, Username);
} else {
Toast.makeText(CreateAccountActivity.this,
"Empty Fields Not Allowed",
Toast.LENGTH_LONG)
.show();
}
}
});
}
private void createUserEmailAccount(String email, String password, final String username) {
if (!TextUtils.isEmpty(email) && !TextUtils.isEmpty(password) && !TextUtils.isEmpty(username)) {
progress_bar.setVisibility((View.VISIBLE));
firebaseAuth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener( CreateAccountActivity.this,new OnCompleteListener<AuthResult>() {
@Override
public void onComplete( @NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Map<String, Object> userobj = new HashMap<>();
userobj.put("userId", "currentuserId");
userobj.put("username", username);
db.collection("journal")
.add(userobj)
.addOnSuccessListener(new OnSuccessListener<DocumentReference>() {
@Override
public void onSuccess(DocumentReference documentReference) {
Log.d(TAG, "DocumentSnapshot successfully written!");
progress_bar.setVisibility(View.INVISIBLE);
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Log.w(TAG, "Error writing document", e);
}
});
} else {
Log.w(TAG, "createUserWithEmail:failure", task.getException());
Toast.makeText(CreateAccountActivity.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
progress_bar.setVisibility(View.INVISIBLE);
}
}
});
}
}
