Hi all, I want to import the android setting source code which is from AOSP into Eclipse or Android Studio so that I can rewrite the Settings App. Firstly, I import the setting source code as a java project. Then, I add the library from "out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/classes.jar". In eclipse, most of the errors disappear. However, there is one error: "The type of libcore.icu.LocaleData can not be resolved". How to solve it? If my development method or environment is not right. Welcome give me some advice! Thank you.
