The project currently contains an application module named app which uses the com.android.application build plugin. This module will serve as the base feature module for the modified project, so needs to be given a more descriptive name. Within the project tool window, right-click on the app entry and select the Refactor -> Rename… option from the menu. In the Rename Module dialog, change the module name to applinkingbase before clicking on the OK button.
