java.lang.NoClassDefFoundError : android. 支持.v7.app.AppCompatDelegateImplV11

Question

我正在使用我的应用程序 AppCompat 来处理 Material 设计。运行应用程序失败，然后在继承自 AppCompactActivity 的 MainActivity 类的 onCreate 中显示以下错误:

java.lang.NoClassDefFoundError: android.support.v7.app.AppCompatDelegateImplV11

目前我的应用程序还使用 Facebook SDK 和 Google Play 服务。我搜索了一个解决方案，但没有找到任何工作:(。有人可以帮助我感谢他。我留下了完整的错误日志。

PD:我正在使用 Eclipse。

Answer 1

我有同样的错误!它也没有给您明确的问题原因。这是多么痛苦啊。我花了一整天的时间试图找出解决办法。这是我的发现——Google Play 服务是一个庞大的代码库。对于我使用的所有其他通用库，我达到了 65k 方法的 dex 限制。这导致了我遇到的错误(也可能是你的错误)。

降低它的一些技巧:

1. 有选择地选择您要使用的 Google Play 服务。 Directions here
2. 如果这不起作用，请尝试对您的应用程序进行多索引处理。 Directions here .注意:如果遇到问题，请尝试扩展MultiDexApplication 而不是 Application。
3. 清理项目，重新启动 Eclipse，和/或重新启动您的计算机。这解决了与上述 dex 问题无关的类似问题。
