我正在尝试在Android Studio中使用Proguard。
我有一个大家都有的经典问题,那就是“类或接口的未解析引用”。
就像我到处阅读一样,我试图添加
-dontwarn
命令发送到proguard-project.txt文件,但它不会更改任何内容。
也许我的设置只是忽略了proguard-project.txt文件?一切似乎都很好,但我对Android Studio、gradle和proguard都是新手,所以我可能错过了一些东西!感谢任何帮助。
以下是我的文件:
proguard-project.txt
-dontwarn org.apache.**
项目属性
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
# Project target.
target=android-15
android.library=false
