Android Firebase이 새로운 사용자를 만들지 않습니다.

Question

누군가가 나를 도울 수 있기를 바랍니다. 아래 내 작성/등록 사용자에 대한 내 코드입니다. Android Studio와 Firebase를 사용하고 있습니다. 어떤 이유로 코드가 새 사용자를 만들지 않습니다. 수동으로 데이터베이스에 사용자를 추가 할 수 있지만 에뮬레이터를 실행하고 로그인을 테스트 할 때 새 사용자를 만들 수 없습니다. 프로그램이 progressDialog를 실행할 때 멈추게됩니다. progressDialog를 제거하면 응답이 없으므로 createUserWithEmailAndPassword()가 호출 될 때 프로그램이 멈추는 것으로 보입니다. Firebase 콘솔에서 전자 메일 및 암호 인증을 활성화했습니다. 나는 문제가 무엇인지 모르며 코딩에보다 숙련 된 사람으로부터 통찰력을 얻었습니다. 모두에게 미리 감사드립니다.

} 

Answer 1

사용자를 전혀 만들지 않으므로 이러한 현상이 발생합니다. 따라서 onComplete 방법의 경우 Firebase 현재 사용자를 획득해야합니다.

mAuth.createUserWithEmailAndPassword(email,password).addOnCompleteListener(new OnCompleteListener<AuthResult>() { 
    @Override 
    public void onComplete(@NonNull Task<AuthResult> task) { 
     progressDialog.dismiss(); 
     if (task.isSuccessful()){ 
     FirebaseUser user = mAuth.getCurrentUser(); //You Firebase user 
     // user registered, start profile activity 
     Toast.makeText(RegisterPage.this,"Account Created",Toast.LENGTH_LONG).show(); 

     finish(); 
     startActivity(new Intent(getApplicationContext(), UserMainPage.class)); 
     } 
     else{ 
     Toast.makeText(RegisterPage.this,"Could not create account. Please try again",Toast.LENGTH_SHORT).show(); 
     } 
    } 
    }); 

는 희망이 도움이 : 그래서 if (task.isSuccessful()이 같은 사용자를 얻을.
