'No debuggable processes in Logcat and debug window
I got so confused by android studio.it can't identify my device.
like this

the app is build in debug mode.

besides, if I kill the adb server and restart the adb, it can identify the device and the process, the after a while, if I kill the app, and reopen it, the android studio cannot identify it again...
No other processes occupy adb process.I even reinstalled my Android Studio, but still not work.
Solution 1:[1]
I reinstall the platform-tools in android studio->sdk manager. And then the problem was solved.
