- 我試圖通過Firebase構建具有登錄/註冊功能的應用程序。我正在和一個合作伙伴（他在Linux上，我在Mac上）一起工作，他能夠獲得身份驗證的工作，但由於某種原因，我不是。我們在SDK管理器中檢查了所有相同的代碼，SDK工具，運行相同版本的所有內容。
這裏的gradle這個文件：Android驗證碼firebase錯誤：找不到com.google.firebase.auth的本地模塊描述符類
compile 'com.android.support:appcompat-v7:25.3.0' compile 'com.android.support.constraint:constraint-layout:1.0.2' compile 'com.google.firebase:firebase-auth:10.2.1' compile 'com.android.support:design:25.3.0' testCompile 'junit:junit:4.12'，代碼：
public class RegisterActivity extends AppCompatActivity {
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthListener;
private EditText mUsernameField;
private EditText mPasswordField;
private EditText mConfirmPasswordField;
private Button mRegisterButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
mUsernameField = (EditText) findViewById(R.id.enterUsername);
mPasswordField = (EditText) findViewById(R.id.enterPassword);

mRegisterButton = (Button) findViewById(R.id.confirmRegistration);
mRegisterButton.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {
createAccount(mUsernameField.getText().toString(), mPasswordField.getText().toString());
}
});
mAuth = FirebaseAuth.getInstance();
mAuthListener = new FirebaseAuth.AuthStateListener() {
@Override
public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
FirebaseUser user = firebaseAuth.getCurrentUser();
if (user != null) {
// User is signed in

if (!task.isSuccessful()) {
Toast.makeText(RegisterActivity.this, R.string.register_failed,
Toast.LENGTH_SHORT).show();
}
else {
Intent intent = new Intent(RegisterActivity.this, MainActivity.class);
RegisterActivity.this.startActivity(intent);
finish();

- 差不多一切都被教科書從火力地堡網站。請幫助，我們一直堅持這個小時，並沒有其他類似的問題有幫助。
選項1是有益的。 –
