LibGDX安卓应用程序在启动时崩溃

Question

当我运行我的项目时，它会立即崩溃并输出。我创造了一个新的项目，但它也崩溃了。我正在使用Eclipse，因为我真的很喜欢它。

编辑：--它在Android中工作得很好，所以它必须与有关。但如果可能的话，我真的很想坚持使用Eclipse。

Answer 1

找不到se.wiklund.memblock.AndroidLauncher类。检查您的依赖项/库，因为日志警告在DexPathList中找不到它。

在发布一个问题之前，你应该找出类似的问题：

Android ClassNotFoundException:没有找到路径上的类

我的project.It也出现了同样的问题，这是因为我的项目和我在项目中添加的库项目之间在安卓支持库版本中发生了冲突。将相同版本的android支持库放在您的项目和库项目中，并清理构建.一切都会正常的..。

在path上找不到类: dexpathlist列表

这里也有同样的问题。对我起作用的是添加android-support-v4.jar作为一个库，并确保它在properties、->、Build、-> Order & export上进行了检查。有人提到了这里

Answer 2

我通过安装这个Gradle插件(http://dist.springsource.com/snapshot/TOOLS/gradle/nightly)来解决这个问题。我以前使用过与Eclipse集成的组件。
