Android调试底层服务

　　之前调试过VOLD,调试起来极为麻烦，稍微改一点就要编译整个系统，然后烧写system.img。极为耗时，经过多时经验总结出来了类似调试应用程序的调试方法，高效快速。这里先还以ＶＯＬＤ为例子。

　　

　　修改源码后单独编译ＶＯＬＤ：

　　$ mmm system/vold

然后执行以下脚本，就可以直接观察现象了:

#!/bin/sh# vold 调试脚本# 作者:kangear# 2014-02-09# build vold# mmm system/vold  &&# send vold# sz out/target/product/rk30sdk/system/bin/vold  &&# pushadb push /root/ybk-hw/ybkMisc/out/target/product/rk30sdk/system/bin/vold /system/bin &&# chmodadb shell busybox chmod 777 /system/bin/vold   &&# stop voldadb shell setprop ctl.stop vold  &&# start voldadb shell setprop ctl.start vold

#!/bin/sh# services 调试脚本# 作者:kangear# 2014-02-09# build vold# mmm frameworks/base/services/java/ &&/root/remount.sh &&# send vold# sz out/target/product/rk30sdk/system/bin/vold  &&# pushadb push /root/ybk-hw/ybkMisc/out/target/product/rk30sdk/system/framework/services.jar /system/framework/ &&# rebootadb shell reboot

最为方便的是adb sync来同步代码，其中启动和关闭部分还算有用。adb push那些太麻烦了。
