Android dex 在构建时给出 BufferOverflowException

Question

当编译一个特定的 Android 项目时，并且只在我的 Windows 机器上，我从 dex 中得到一个 java.nio.BufferOverflowException。使用 Eclipse 和使用 Ant 时都会出现此问题。

使用 Ant 时的输出是:

...
  [dex] Pre-Dexing C:\MyProject\libs\android-support-v4.jar -> android-support-v4-5f5341d3c1b10a79d7d93f9c1e64421e.jar

使用 Eclipse 时，消息更短但相似:

[2013-11-01 14:29:44] APK file is not created for Project: 
[2013-11-01 14:29:46 - Dex Loader] Unable to execute dex: java.nio.BufferOverflowException. Check the Eclipse log for stack trace.
[2013-11-01 14:29:46 - MyProject] Conversion to Dalvik format failed: Unable to execute dex: java.nio.BufferOverflowException. Check the Eclipse log for stack trace.

就像我说的，我的 MacBook 上没有这个问题，即使它们都升级到最新版本的 Android 构建工具:19.0.0。

Answer 1

无需将构建工具降级回 18.1.1¹，此问题为 fixed with build tools 19.0.1 .

如果您出于某种原因无法使用 19.0.1，则:

确保 android:targetSdkVersion 的值在 AndroidManifest.xml 中匹配 target=android-<value>在 project.properties 中。如果这两个值不相同，使用构建工具版本 19.0.0 构建将以 BufferOverflowException 结束。 ^Source

这篇文章的评论也表明您至少需要针对 19 (android-19)。如果您的目标是 < 19，如果此解决方案也适用，请发表评论。

This is how the fix looks为我的项目。 The related AOSP issue is #61710.

^{1 如果确实需要降级，不需要卸载build tools 19.0.0，只需安装18.1.1并添加sdk.buildtools=18.1.1即可到 local.properties文件。}
