硬软件情况：
NEXUS 5X 32G
Android7.1 + SuperSU+ Xposed Install(XDebuggable)
问题：开启DDMS时发现进程无法访问，经过一番搜索发现是ro.debuggable值为0导致。
# adb shell "/data/local/tmp/mprop"
Usage: propmod [prop_name] [prop_value]
e.g.: propmod ro.secure 0
采取github方法未果，转向看雪论坛，下载mprop170119.zip 解压后上传至手机
└─# adb push mprop /data/local/tmp
mprop: 1 file pushed, 0 skipped. 90.9 MB/s (13784 bytes in 0.000s)
按看雪论坛流程
# 修改init进程中的ro属性判断逻辑
adb shell "/data/local/tmp/mprop"
# 之后就可以修改任意ro属性了，如
adb shell "setprop ro.debuggable 1"
结果未成功
└─# adb shell getprop ro.debuggable
└─# adb shell "/data/local/tmp/mprop"

再次开启DDMS发现进程能正常显示在列表中
缺点：无法持久化，手机重启需要重设。另外在重启adbd服务前，启动DDMS也能看到手机中新启动的进程信息，但无法看到启动前的进程，有点非root用户的感觉。重启服务后就能完整看到手机中所有进程信息。
