无法使用 proguard 构建发布 apk

Question

无法使用 proguard 构建发布 apk。没有proguard，一切都会很好。我已经尝试了许多其他在互联网上找到的 proguard 规则，但均未成功。我怀疑问题在于我使用 VectorDrawable 和 minApi 19。

问题出在 proguard-rules 的路径中

修改了这段代码

proguardFiles getDefaultProguardFile('proguard-android.txt'), '$project.rootDir/tools/proguard-rules.pro'

到这里

proguardFiles getDefaultProguardFile('proguard-android.txt'), '../tools/proguard-rules.pro'
