Android BuildConfig Guide

In Android, BuildConfig is an automatically generated class used to store constants and variables generated during the build process. It can be used to retrieve some information about the application, such as the package name and version number.

To use the BuildConfig class, you just need to directly reference it in your code, for example:

String packageName = BuildConfig.APPLICATION_ID;
int versionCode = BuildConfig.VERSION_CODE;
String versionName = BuildConfig.VERSION_NAME;

In the code above, we obtained the package name, version number, and version name of the application through the BuildConfig class. These information are automatically generated and stored in the BuildConfig class during the application build, making it easy to use in the code.
