Question

所以我想出了如何正确地与Google签约。凉。现在，Facebook呢？

当我登录Facebook时出现错误，例如错误表明我已经拥有具有相同凭据但具有不同社交提供商的Firebase帐户，我得到了＆＃34;退出Facebook＆＃34;按钮。 更清楚：

我尝试登录Facebook，然后收到错误（这不是我的问题！），但问题是，Facebook的按钮现在开启了＃34 ;退出＆＃34;。当它仍然 ＆＃34;使用Facebook＆＃34; 登录时。我知道为什么会这样;它的错误在于 Firebase ，Facebook认为我已登录。

但真正的问题是，如何正确退出Facebook？ FirebaseAuth.getInstance().signout()似乎没有注销 Facebook 本身。

这是我当前的logout()方法：

static void logOut(final Context context) {
    new SweetAlertDialog(context, SweetAlertDialog.WARNING_TYPE)
        .showCancelButton(true)
        .setTitleText(context.getString(R.string.areYouSure))
        .setContentText(context.getString(R.string.logoutMSG))
        .setCancelText(context.getString(android.R.string.no))
        .setCancelClickListener(new SweetAlertDialog.OnSweetClickListener() {
            @Override
            public void onClick(SweetAlertDialog sweetAlertDialog) {
                sweetAlertDialog.dismiss();
            }
        })
        .setConfirmText(context.getString(R.string.yes))
        .setConfirmClickListener(new SweetAlertDialog.OnSweetClickListener() {
            @Override
            public void onClick(final SweetAlertDialog sweetAlertDialog) {
                //region Google
                GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                    .requestIdToken(context.getString(R.string.default_web_client_id))
                    .requestEmail()
                    .build();
                final GoogleApiClient mGoogleApiClient = new GoogleApiClient.Builder(context)
                    .enableAutoManage((FragmentActivity) context, new GoogleApiClient.OnConnectionFailedListener() {
                        @Override
                        public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
                            FirebaseCrash.log(connectionResult.getErrorMessage());
                            Toast.makeText(context, context.getString(R.string.error), Toast.LENGTH_SHORT).show();
                        }
                    })
                    .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
                    .build();

我遇到了类似的问题，并使用firebase Auth实例和facebook LoginManager实例解决了问题

FirebaseAuth.getInstance().signOut();
LoginManager.getInstance().logOut();

Answer 2

Firebase 本身、Google 和 Facebook 的 3 种退出方法。

//LOG_OUT
    public static void signOut(Activity activity) {
        if (mAuth == null)
            mAuth = FirebaseAuth.getInstance();

        //Firebase SignOut
        mAuth.signOut();

        //Google SignOut
        SignInWithGoogle signInWithGoogle = new SignInWithGoogle(activity);
        signInWithGoogle.getGoogleSignInClient().signOut()
                .addOnCompleteListener(activity, new OnCompleteListener<Void>() {
            @Override
            public void onComplete(@NonNull Task<Void> task) {
                Log.d(TAG, "Google Sign Out!!! ");
            }
        });

        //Facebook SignOut
        LoginManager.getInstance().logOut();
    }

如何使用Firebase在Android上正确退出Facebook？
