什么是差异。 default.properties和project.properties之间?

我想询问Android项目中default.properties和project.properties文件之间的区别。 尝试谷歌搜索它,但没有正确的答案。 谢谢!

default.properties which is the main project's properties file containing information such as the build platform target and the library dependencies has been renamed project.properties.
