Android中build.prop文件与getprop命令-创新互联
Android 中build.prop 文件与 getprop 命令
在android系统中，它的根文件系统下有几个用于启动系统时需要的配置文件：
- /init.rc
- /default.prop
- /system/build.prop
我们先看看 build.prop 里面到底有些什么东西：
E:\AndroidProject\NowaMagic>adb shell shell@android:/ $ su su root@android:/ # cd system cd system root@android:/system # cat build.prop cat build.prop # begin build properties # autogenerated by buildinfo.sh ro.build.id=JRO03L ro.build.display.id=JRO03L ro.build.version.incremental=JLB21.0 ro.build.version.sdk=16 ro.build.version.codename=REL ro.build.version.release=4.1.1 ro.build.date=Thu Aug 1 17:50:59 CST 2013 ro.build.date.utc=1375350659 ro.build.type=user ro.build.user=builder ro.build.host=taishan ro.build.tags=release-keys ro.product.model=MI 2 ro.product.brand=Xiaomi ro.product.name=aries ro.product.device=aries ro.product.board=MSM8960 ro.product.cpu.abi=armeabi-v7a ro.product.cpu.abi2=armeabi ro.product.manufacturer=Xiaomi ro.product.locale.language=zh ro.product.locale.region=CN ro.wifi.channels= ro.board.platform=msm8960 #
