Question

我需要将Facebook和Google Plus整合到相同的活动中，但我没有在其中获得成功。我已经在单个项目中尝试了它们并且它们工作正常但是当我将两个项目一起添加时我的应用程序崩溃了。即使我也尝试过自定义按钮，但它们也不起作用。目前我的Facebook部分工作正常，但是当我在登录时点击Google的按钮时出现错误。我在这些方法中遇到错误：

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

和

private void signInWithGplus() {
    if (!mGoogleApiClient.isConnecting()) {
        mSignInClicked = true;
        resolveSignInError();
    }
}

Answer 1

我昨天通过在onClick部分

中添加几行来解决我的问题

if (mGoogleApiClient.isConnected()) {
            getProfileInformation();
        } else {
            signInWithGplus();
            getProfileInformation();
        } 
}

Answer 2

如果您第一次拨打signInWithGplus()，它会尝试访问此时为空的mConnectionResult。

之所以这样，是因为你只是在onConnectionFailed()中设置它而不会被调用。

如何在Android项目的同一活动中整合Google Plus和Facebook身份验证？
