Android dependencies file appears in the new project

The new version of ADT modifies the third-party jar import method. Previously, it can be associated in the project, and referencelibrary will be automatically added to the project. In the new version of ADT environment, you only need to create a new libs folder under the project directory. Note that libs is not Lib, and then copy the third-party jar to the folder, eclipse will automatically add this jar to the android dependencies folder. You do not have to modify it by yourself through buildpath or referencelibrary. In addition, if multiple projects are associated, for example, when project a is set to islibaray and Project B is introduced to project, the jar compiled by Project A is automatically placed in the android dependencies folder.
