IDA远程调试 The debugger could not attach to the selected process. irs_recv 等待的操作过时

IDA连接android_server 选中进程点ok之后 连接不上报错

The debugger could not attach to the selected process.

This can perhaps indicate the process was just terminated, or that you dot't have the necessary privileges.

输出窗口提示 irs_recv 等待的操作过时

原因：

Android5.0之后默认启用了 SELinux/SEAndroid 

查看是否开启

getenforce

解决办法：

setenforce 0

或者

echo 0 > /sys/fs/selinux/enforce
