在模拟器中运行时，libgdx 在 helloworld 应用程序上

libgdx throwing an exception on helloworld app when ran in emulator(在模拟器中运行时，libgdx 在 helloworld 应用程序上引发异常)

问题描述

我已按照 http://www.youtube.com 上的教程进行操作/watch?v=vLx_72qxK_0&feature=player_embedded 并使用 libgdx 库创建了一个简单的应用程序，该程序使应用程序具有红色背景.

I've followed the tutorial on http://www.youtube.com/watch?v=vLx_72qxK_0&feature=player_embedded and created a simple app with the libgdx library that makes an application with a red background.

当我将它作为独立的桌面应用程序运行时，它运行良好，但是当我运行 -android 版本时，会引发以下异常并且应用程序无法启动.

This works fine when I run it as a stand alone desktop app, but when I run the -android version the exception below is thrown and the application fails to start.

有人对这个库有任何经验吗?

Does anyone have any experience with this library?

推荐答案

通过确保 armeabi 和 armeabi-v7a 文件夹位于 android 项目的/libs 中来解决问题.

fixed the issue by making sure the armeabi and armeabi-v7a folders were in /libs of the android project.
