LibGDX And​​roid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。我创建了一个新的项目，但它也崩溃了。我正在使用Eclipse，因为我非常喜欢它。

编辑：它在Android Studio中运行良好，因此它必须与Eclipse有关。但是如果可能的话，我真的想坚持使用Eclipse。

Answer 1

找不到

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

在发布之前你应该寻找类似的问题：

Android ClassNotFoundException: Didn't find class on path

  

我的项目遇到了同样的问题。这是因为我的项目和我在项目中添加的库项目之间的android支持库版本冲突。将相同版本的android支持库放在您包含的项目和库项目中并清理构建......一切都会工作......

Didn't find class on path: dexpathlist

  

这里的问题相同。对我有用的是将android-support-v4.jar添加为lib并确保在项目属性上检查 - ＆gt;构建路径 - ＆gt;订单＆amp;出口。有人提到here

Answer 2

我通过安装此Gradle插件解决了这个问题：（http://dist.springsource.com/snapshot/TOOLS/gradle/nightly）。我之前使用过与Eclipse集成的那个。
