贝宝服务没有启动（沙箱帐户），我得到以下错误

问题描述：

我有一个活动命名为示例activity.From该活动，我打开了一个意图，这是一个具有贝宝服务的navigationlayout1活动。应该像他们（贝宝）一样在他们的示例中添加创建此服务。我以前没有使用过multidex选项时没有遇到过这个问题。贝宝服务没有启动（沙箱帐户），我得到以下错误

我得到了一个像“退出值2”的错误，由于这个错误，我的gradle无法完成。我已经做了一些研究来清除这个错误。

最后我以前的错误（退出值2）被清除。我很高兴，因为现在没有错误。但意外的是我得到了这个错误。过去三天我一直在错误地停顿。我一直在研究。这是在这里提出了不浪费我的时间出现在正确的时间更多..Please帮我

我的代码是

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

    startActivity(intent);

这个页面将被打开

}

但我得到上面的错误。请帮助我

答

你可以用 "com.paypal.sdk:paypal-android-sdk:2.14.2"

compile 'com.squareup.okhttp3:okhttp:3.3.1' 
compile 'com.squareup.okio:okio:1.8.0'

或者添加这两gradle这个文件，你可以下载OkHttp.jar和Okio.jar，并把那些你libs文件夹下。
