无法修复Android Studio中的包路径错误

Question

As you can see in the screenshot above, all the imports of LipeRMI classes are in vain. What should be the right path statement to have them imported correctly? I face the same error in MainActivity for: import lipermi.handler.CallHandler; import lipermi.net.Client; import lipermi.handler.CallHandler; import lipermi.net.Client;

I know such questions regarding android studio have been asked many times but I just fail to understand how to fix this problem. FYI, I dragged the net.sf.lipermi folder into com.example.akash.chatapplication folder.

Thank you for your time. :)

EDIT - After following Tanis.7x's answer, this is the updated hierarchy as well as the MainActivity code-

Answer 1

您应该将src/main/com/example/akash/chatapplication/net移至src/main

Answer 2

By dragging the net.sf.lipermi folder into the com.example.akash.chatapplication folder, you have altered the package for those classes.

This won't compile, because the folder path needs to match these classes' package declaration. This this case, the package would have to be com.example.akash.chatapplication.net.sf.lipermi , which is clearly not what you want.

If you really need to copy these classes into your project, you should copy them into the src/main folder instead of into your application's package.

The best route is to include these files as a dependency in your build.gradle . However, not all libraries offer this option. If that library provides a JAR file, you should instead include that JAR in your project's libs folder. Including the raw source in your project should always be a last resort.
