在某些时候需要将三方apk集成为android ROM内置应用，如果三方应用内部有大量的shared library文件，则需求大量时间为其编写Android.bp或者Android.mk。
为了提高工作效率，我特意用python实现了一个简易版本其功能如下：
1.将APK文件解压，比如APK文件名为Test.APK
2.在Test/lib目录下创建Android.bp文件
3.读取Test/lib目录的子目录列表
4.针对armeabi-v7a和arm64-v8a目录,分别读取其shared library列表并逐个生成对应的prebuild脚本，然后写入Android.bp(当前版本只处理了armeabi-v7a)
