android - 如何在 Android 项目的同一个 Activity 中将 Google Plus 和 Facebook 身份验证集成在一起？

Question

我需要将 Facebook 和 Google Plus 整合到同一 Activity 中，但我没有成功。我在单个项目中都尝试过，它们工作正常，但是当我将两个项目添加到一起时，我的应用程序崩溃了。即使我也用自定义按钮尝试过它们，但它们也不起作用。 目前我的 Facebook 部分工作正常，但在登录时单击 Google 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();
    }
}

我在这个类中实现:

public class LoginActivity extends Activity implements OnClickListener,
    ConnectionCallbacks, OnConnectionFailedListener {
// Your Facebook APP ID
private static String APP_ID = "XXXXXXXXXXXXXXX"; // Replace with your App
                                                    // ID

// Strings of Facebook

        fb_mUserEmail = "", fb_verified_value = "", fb_Task_message;

我昨天通过在 onClick 部分添加几行来自己解决了我的问题

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