我的应用程序的方法计数高于64k的限制,所以我使用Proguard来减少它.
一切都适用于发布版本.
另一方面,调试版本只能用于棒棒糖设备.当在Lollipop设备上启动时,我总是有臭名昭着的错误:
com.android.dex.DexIndexOverflowException:方法ID不在[0,0xffff]中:65536
这是我在应用程序级别毕业文件中所拥有的:
buildTypes { debug { minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro' } release { shrinkResources true minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro' } }
我试图在调试版本中删除minifyEnabled true,然后构建失败也在Lollipop上,因此proguard正在运行!但不是在棒棒糖前.
对于我所知道的,minifyEnabled不应该是平台依赖的,所以也许构建过程在前Lollipop设备上跳过它(因为我不知道是什么原因).
有人知道这个问题的解决方案吗?
PS.我知道多方面的可能性,但我将其作为我的最后手段.

解决方法
如果你想尝试减少方法计数,或至少你想了解从发布到调试的区别,我建议你尝试看看在AS 2.2预览5中提供的dex计数,他们有一个YouTube视频(也许从谷歌IO),这使得它很容易计算你的方法.
这只是用于计数方法,如果仍然使用相同的buildToolsVersion“23.0.3”,您应该在两个版本的AS中都能获得完全相同的apk文件(除了AS 2.2附带其自己的JDK版本,不应该在你的方式).
免责声明:我从来没有使用过这种工具,所以在实际找到凶手之后,我不知道该推荐什么.
编辑:这里是“Apk Analyzer”的视频https://youtu.be/csaXml4xtN8?t=331,它位于“Build”菜单中.不要尝试早于2.2预览3或更高版本的评论,他们预览了一些直到后来才发布的内容.
编辑2:也是为什么只在使用shrinkResources的时候发布?这就是为了消除不必要的方法:“minifyEnabled” vs “shrinkResources” – what’s the difference? and how to get the saved space?
