aapt
● Android Asset Packaging Tool● 다음 명령어로 .apk 파일에 포함된 리소스 분석 가능
$ aapt d --values resources framework-res.apk
spec resource 0x01040029 android:string/default_sms_application: flags=0x00000000
resource 0x01040029 android:string/default_sms_application: t=0x03 d=0x00001e00 (s=0x0008 r=0x00)
(string8) "com.android.mms"
수정 전략
● 안드로이드 기본 빌드 스크립트를 이용해 factory image 생성
● 유지 보수가 가능○ bug fix 또는 major 업그레이드가 되었을 때 따라가기 편해야 한다.
● 결론
○ 원래 코드는 되도록이면 건드리지 말자
○ 수정하고 싶으면 원래 코드 바깥에서 건드리자
되는데요...
