Android Eclipse로 Debugging

1. full source 를 compile 한다

    - ex) froyo

 

2. build 완료 확인

    - system.img, userdata.img, ramdisk.img 확인

    - /froyo/out/target/product/generic$

 

3. Linux에서 빌드된 souce code 과 object를 window system 으로 가져온다.

    - source code : /froyo/packages/apps/Settings$

→ code review를 위해 device, frameworks, packages 를 한번에 copy

    - obj code : /froyo/out

 

4. Eclipse에서 Settings package를 넣고 build

    1) File - New - Project - Android Project

        Create project from existing source 에서 Settings package path 설정

    2) Compile

 

5. Compile error 수정

    - project 에서 properties 실행

    1) add framework lib

i. Java Build Path 에서 Libraries 선택

ii. Add External JARs 실행하여 아래 jar 추가

    /out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/classes.jar

    2) Build Oder 수정

i. Java Build Path 에서 Order and Export 선택

ii. 5-1)에서 추가된 classes.jar를 최상위로 선택

 

6. APK 설치

    - install package in data

>adb remount                                    

>adb shell rm /system/app/Settings.apk   

>adb uninstall com.android.settings         

• >adb install Settings.apk                       

 

• overwrite package in system

>adb remount                                 

>adb push d:\~~~~\*.apk /system/app

 

--> system.img 로 만들어지는것과

직접 push 하는것이 왜 size 차이가 나는걸까?

adb shell mount -o rw,remount -t yaffs2 /dev/block/mtdblock0 /system

 

 

 

 

 

♣ TroubleShooting

 

1. INSTALL_FAILED_SHARED_USER_INCOMPATIBLE

    - adb error

        pkg: /data/local/tmp/Settings.apk

Failure [INSTALL_FAILED_SHARED_USER_INCOMPATIBLE]
