我已经查看了有关此错误的大多数其他线程，但没有找到答案。
几周前，我使用插件和带有插件的示例项目开始了一个新项目。添加了我自己的各种功能和设计，运行项目没有问题。
然后在 2 天前更新到 ADT 17，这对我来说严重搞砸了。开始出现类路径错误等等。然后我恢复到修复了错误的 adt 16，我的项目编译得很好，但是一旦我运行它，它就会在测试设备上崩溃。
我检查了我的合规级别是否正确，检查了库路径、api 版本、清单 xml，基本上所有内容。我不明白过去可以完美运行的东西现在如何无法正常工作。
我继续卸载所有东西，并在 sdk 的 ADT 和 java 上重新安装，但无济于事，即使只是尝试运行示例项目也会崩溃。
我还从设备上卸载了该应用程序并重新启动了设备并清除了缓存。我已经走到了尽头。就像我说的，我已经检查了库和所有内容，它只是这个运行时错误。
我还增加了连接超时，并在我的清单中添加了“android:installLocation="preferExternal"，没有变化。
请帮忙，代码不会有问题，因为它运行良好。
