Android Studio 从2.2升级到2.3后，因为svn地址迁移所以重新导入项目，发现报了如上的错误。 进入到报错的目录可以发现这些.9的图片都是存在且是正常的.9图片；而且这些图片并不是我倒入进去的，而是V7或引用其他的库编译时自动生成的。 试了百度里面很多办法都没能解决，最后在伟大的stackoverflow上面找到了解决方案，在文末附上链接。下面记录下尝试过的办法（stackoverflow也有写）： 1. 排查是否有不合格的.9图片。（实际上报错图片不是手动引入的） 2. 检查png图片是否合格。（比如由jpg直接改后缀的，而不是导出的） 3. 在build.gradle加入设置：
aaptOptions {
cruncherEnabled =
false
useNewCruncher=
false
}
4. 清除报错路径缓存 5. clean或者rebuild项目
以上的方法都不能解决这个问题，下面说下stackoverflow上的解决办法： 1. According to release notes of Android Studio version 2.3, build cache is enabled by default. 2. so we should disable this setting. Here is official guide, Android Studio/User Guide/build-cache(linkhttps://developer.android.com/studio/build/build-cache.html). 3. go to gradle.properties file, and disable build cache. // To re-enable the build cache, either delete the following // line or set the property to ‘true’. android.enableBuildCache=false the other way is to modify build cache dir by adding //first line can be skipped because true is the default value by 2.3 android.enableBuildCache=true android.buildCacheDir =c:\temp\
翻译过来就是： 1. 根据Android Studio版本2.3的发行说明，默认情况下启用构建缓存。 2. 所以我们应该禁用这个设置。这是官方指南，Android Studio/User Guide/build-cache（链接https://developer.android.com/studio/build/build-cache.html）。 3. 打开gradle.properties文件，并禁用构建缓存。 android.enableBuildCache=false 另一种方法是通过添加以下代码来修改构建缓存目录 //first line can be skipped because true is the default value by 2.3 android.enableBuildCache=true android.buildCacheDir =c:\temp\
以上问题解决，可以通过编译。 Stackoverflow问题地址： http://stackoverflow.com/questions/42622654/some-file-crunching-failed-mergedebugresources-failed
