Question

Googe登录无法在离子型Android应用程序中运行，当我运行ionic serve时，在Web应用程序中可以正常运行。

应用程序模块：

    const firebaseConfig = {
      // fire base config here copied from the console.
    };

    @NgModule({
      declarations: [MyApp, AboutPage, ContactPage, HomePage, TabsPage],
      imports: [
        BrowserModule,
        IonicModule.forRoot(MyApp),
        AngularFireModule.initializeApp(firebaseConfig),
        AngularFireAuthModule,
        ComponentsModule
      ],
      bootstrap: [IonicApp],
      entryComponents: [MyApp, AboutPage, ContactPage, HomePage, TabsPage],
      providers: [
        StatusBar,
        SplashScreen,
        { provide: ErrorHandler, useClass: IonicErrorHandler }
      ]
    })
    export class AppModule {}

我已经安装了cordova-support-google-services软件包并添加了google-services.json文件，该文件是从firebase控制台下载的，并将其放在platforms/android/app/目录中。

    @Injectable({ providedIn: "root" })
export class AuthService {
  user$: Observable<User>;

  constructor(
    private afAuth: AngularFireAuth,
    private afs: AngularFirestore,
    private router: Router
  ) {
    this.user$ = this.afAuth.authState.pipe(
      switchMap(user => {
        // Logged in
        if (user) {
          return this.afs.doc<User>(`users/${user.uid}`).valueChanges();
        } else {
          // Logged out
          return of(null);
        }
      })
    );
  }

  async googleSignin() {
    const provider = new auth.GoogleAuthProvider();
    const credential = await this.afAuth.auth.signInWithPopup(provider);
    return this.updateUserData(credential.user);
  }

  private updateUserData(user) {
    // Sets user data to firestore on login
    const userRef: AngularFirestoreDocument<User> = this.afs.doc(
      `users/${user.uid}`
    );

    const data = {
      uid: user.uid,
      email: user.email,
      displayName: user.displayName,
      photoURL: user.photoURL
    };

    return userRef.set(data, { merge: true });
  }

  async signOut() {
    await this.afAuth.auth.signOut();
    this.router.navigate(["/"]);
  }
}

上面的代码在网络上工作正常，但在android上无法正常工作。单击按钮后，将在chrome浏览器中打开新标签页，并显示google登录信息，成功登录后将显示白色空白页面，未重定向到应用程序，而且在firebase控制台中，我看到用户未通过身份验证。 / p>
