Good job! 我一直想加一个自动打包的Action，只是最近太懒了

But there seems to be a problem with the code and the build fails.

@iamr0s My request is that if you can resolve the problem that this build does not work, please release a new build (v2.8.1 etc.) that includes new translations.

以及要注意.gitignore文件，这个r0s.properties文件是我用于本地打包的配置文件。 android test keys需要与它区别开来。
