android – Paypal服务没有启动(沙盒帐户),我得到低于错误

我有一个名为样本活动的活动.从那个活动我开了一个意图,
这是navigationlayout1活动,它有一个paypal服务.应该添加Oncreate这个服务,就像他们(paypal)在他们的例子中完成的那样.
我之前没有使用multidex选项时没有遇到过这个问题.

我收到“退出值2”之类的错误,由于此错误,我的gradle无法完成.我已经做了一些研究来清除这个错误.

最后我的上一个错误(退出值2)被清除.我很高兴因为现在没有错误.但出乎意料的是我得到了这个错误.过去3天我一直被误导.我一直在研究.这是在这里问问题而不再浪费时间的正确时间..请帮助我

我的代码是

Intent intent = new Intent(getActivity(),NavigationLayout1.class);

   startActivity(intent);

此页面将被打开
