无法在Android应用程序中使用谷歌登录

Question

我已经尝试了这里提到的许多解决方案，但我仍然无法解决这个问题。我收到：

“Google登录失败。com.google.android.gms.common.api.apiException：10”

下面是我的代码：

public class LoginActivity extends Activity {

  private GoogleSignInClient mGoogleSignInClient;
  private FirebaseAuth mAuth = FirebaseAuth.getInstance();
  private static final int RC_SIGN_IN = 1;
  static LoginActivity loginActivity;
  private FirebaseUser currentUser;

  public static LoginActivity getInstance(){
    return loginActivity;
  }
  public FirebaseUser getCurrentUser() {
    return currentUser;
  }

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);

    GoogleSignInOptions gso = new 
    GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken(getString(R.string.default_web_client_id))
            .requestEmail()
            .build();

    mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
    mAuth = FirebaseAuth.getInstance();

    View signInButton = findViewById(R.id.sign_in_button);
    signInButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent signInIntent = mGoogleSignInClient.getSignInIntent();
            startActivityForResult(signInIntent, RC_SIGN_IN);
        }
    });
 }

 @Override
 public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    // Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
    if (requestCode == RC_SIGN_IN) {
        //Here resultCode is 0 & requestCode is 1.  
        Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
        try {
            // This line of code is throwing exception.
            GoogleSignInAccount account = task.getResult(ApiException.class);
            Log.w(TAG, task.getException());
            Log.d(TAG, "firebaseAuthWithGoogle:" + account.getId());
            firebaseAuthWithGoogle(account.getIdToken());
        } catch (ApiException e) {
            // Google Sign In failed, update UI appropriately
            Log.w(TAG, "Google sign in failed", e);
        }
    }
}

附言。我也在同一个项目中使用Firestore数据库。我已经成功地将google-services.json保存在应用程序的文件夹中。
