Android development project source code Android development project

An android project generally includes?

I'm glad that your questions generally include: (1)src directory: the storage location of Java source code, and the MainActivity.java in the project is under this folder.

(2)gen directory: the configuration file automatically generated by the system is stored, and the developer should not change it. Java is a resource index file, which maps the resources in an XML file to the resource ID of Java code. Android development tools will automatically synchronize and modify R.java files according to the XML interface files/icons and constants you put into the res directory. If it cannot be generated automatically, the XML file contains errors.

(3) A list of assets; You can also store resources, but the resource ID will not be generated, and it needs to be accessed in binary form through AssetMenager.

(4)bin directory: it stores the executable files generated after the application is compiled.

(5)libs directory: Store JAR packages used by applications. You can put used third-party JAR packages in this folder.

(6)res directory: storing all resources used by application programs: interface layout, character strings, pictures, multimedia resources, etc. But the biggest difference between it and the assets directory is that the resource files in the res directory will generate static attributes named after the resource file names in the R.java file in the gen directory. (7)AndroidManifest.xml: application-level configuration file, which configures some important information related to the application, including main package name, permissions, program components, etc. This file lists the functions provided by the application. In this file, you can specify the services used by the application (such as telephone service, Internet service, SMS service, GPS service, etc.). ). In addition, when you add a new activity, you also need to configure it in this file. You cannot invoke this activity until it is configured. (8)project.properties file: project environment information, which generally does not need to be modified.
