Question

我想将google plus登录到我的Android应用程序中我已经尝试了几乎所有的源代码，但是我仍然无法实现我的代码中没有任何错误但仍然它不会通过gmail登录，请任何人提供解决方案。

mGoogleApiClient = new GoogleApiClient.Builder(this).addConnectionCallbacks(this).addOnConnectionFailedListener(this).addApi(Plus.API, Plus.PlusOptions.builder().build()).addScope(Plus.SCOPE_PLUS_LOGIN).build();

    }


     protected void onStart() {
            super.onStart();
            mGoogleApiClient.connect();
          }


     protected void onStop() {
            super.onStop();
            if (mGoogleApiClient.isConnected()) {
              mGoogleApiClient.disconnect();
            }
          }


     private void resolveSignInError() {
            if (mConnectionResult.hasResolution()) {
              try {
                mIntentInProgress = true;
                mConnectionResult.startResolutionForResult(this, RC_SIGN_IN);
              } catch (SendIntentException e) {
                mIntentInProgress = false;
                mGoogleApiClient.connect();
              }
            }
          }


     @Override
      public void onConnectionFailed(ConnectionResult result) {
        if (!result.hasResolution()) {
          GooglePlayServicesUtil.getErrorDialog(result.getErrorCode(), this, 0).show();
          return;
        }

        if (!mIntentInProgress) {
          // store mConnectionResult
          mConnectionResult = result;

          if (signedInUser) {
            resolveSignInError();
          }
        }

这可能是您的Google控制台（或Firebase）设置中的一个问题。

此外，您应该考虑使用新的Google登录Android API。在这里，您可以找到分步指南：

Google Plus登录已被弃用，不再受支持（参考下文）。
