Android 系统调试(1) 禁止SeLinux

有时候调试需要关闭SElinux , 下面方式可以临时或永久关闭SELinux

方式一: 

adb shell "echo 0 > /sys/fs/selinux/enforce" //设置SELinux 成为permissive模式
adb shell "echo 1 > /sys/fs/selinux/enforce" //设置SELinux 成为enforcing模式 

方式二: 

adb shell setenforce 1 //设置SELinux 成为enforcing模式 
adb shell setenforce 0 //设置SELinux 成为permissive模式 

方式三: 

diff --git a/system/core/init/selinux.cpp b/system/core/init/selinux.cpp
