How do I use my imported jar?

Question

Ok, this is going to be a really stupid question but I can't figure out a solution. So I added a .jar file to Android Studio the following way:

• exported .jar file using IntelliJ IDEA
• copied .jar to libs folder under app folder in the Project view in Android Studio
• Right clicked the .jar and selected "Add as Library"

The line compile files('libs/MyJar.jar') was added to the build.gradle file. However I cannot figure out how to actually use the classes in the jar. I can't seem to import it at all, and it is as if I didn't actually add anything. What am I doing wrong?

I know this is an idiotic question, but I can't find a solution.

如果按照您的说明添加了jar，并且在添加jar后gradle成功构建，那么您就可以开始在Activity中进行编码，系统会提示您将关联的类文件导入.jar。
