请发布您的代码 –

ur代码在onCreat本身中包含错误。 – KOTIOS

我发布了整个Code.So请帮助我如何解决这个问题以及如何解决OnCreate它自我错误。 @Monica – Venkat

的requestWindoFeature行应该是super.onCreate（SavedInstanceState）在UnitPayerNativeActivity类

我已经改变为你告诉，但我得到同样的错误，因为我张贴错误以上。@ Vaibhav Agarwal。 – Venkat

请清理您的代码并重新构建它，然后删除依赖库，然后重新添加它并重新启动您的系统和仿真器。运行您的项目并查看错误日志。右键单击pro去属性 - > java构建路径 - >库除去主要android4.2或任何你的android lib是除去所有。移除所有。再次清理项目构建。重新启动一切并运行 –

即使同样的问题没有改变@ Vaibhav Agarwal。 – Venkat

从总体上看后，我们使用 “亚行安装位置” 安装APK到模拟器。
