从 Android 应用程序中注销 Google 帐户

Question

如果我的应用程序可以选择使用谷歌帐户登录，我该如何退出？ 注销是从另一个活动完成的。我怎样才能做到这一点？ 请帮忙..

首先像这样在 onCreate 方法中与 Google 建立联系 GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN) .requestEmail() .build();

    GoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this, this)
            .addOnConnectionFailedListener(this)
            .addConnectionCallbacks(this)
            .addApi(Auth.GOOGLE_SIGN_IN_API)
            .build();

GoogleApiClient.connect();

然后：

  Auth.GoogleSignInApi.signOut(GoogleApiClient).setResultCallback(
                    new ResultCallback<Status>() {


                        @Override
                        public void onResult(Status status) {
                            sessionManager.clearSession();
                            Intent i=new Intent(getApplicationContext(),MainActivity.class);
                            startActivity(i);
                            finish();
                            Toast.makeText(getApplicationContext(),"Logout Successfully",Toast.LENGTH_LONG).show();
                        }
                    });
        }
