是否root
public Boolean isRooted(){CommandResult cmdResult ShellUtils.execCommand(su, true);if (cmdResult.errorMsg.equals(Permission denied) || cmdResult.result ! 0) {return false;}else{return true;}
}
复制文件
String[] commands new String[] { mount -o rw,remount /system, cp /mnt/sdcard/xx.apk /system/app/ };public boolean copyFile(String[] cmdText){CommandResult cmdResult ShellUtils.execCommand(cmdText, true);if (cmdResult.errorMsg.equals(Permission denied) || cmdResult.result ! 0) {return false;}else{return true;}
}
我暂时就举这两个例子只要你会Shell什么操作都是可以的。 博客名称王乐平博客 博客地址http://blog.lepingde.com CSDN博客地址http://blog.csdn.net/lecepin
