Description of related parameters:

1. Project name: name of the folder containing the project

2. package name: the package name follows the Java specification. It is important to use the package name to distinguish different classes. Activity name: this is the main class name of the project, this class will be a subclass of the android activity class. An activity class is a simple class for starting and controlling programs. It can create an interface as needed, but not required.

3. Application name: An easy-to-read title is on your application (I have not figured out what is going on, but I still use it well if I have not entered it ).

 

Now JDK is complete.
