Yesterday, Android studio ran a few updates and thereafter, whenever I start Android Device Monitor (ADM), it put my emulator to OFFLINE and I cannot access it even after killing the ADB server and restarting it.

Until I start ADM, everything is fine; when I run the ADB Devices, I see the emulator online but the moment I start the ADM to pull the database out, it goes to OFFLINE.

This is what I did to troubleshoot:

  1. ran adb kill-server
  2. ran adb start-server
  3. reset Android studio by deleting the setting folders
  4. restarted the WINDOWS

but nothing helped by far and any help would be greatly appreciated.

This is on Android Studio 2.2.3

  • Since everything failed, I just uninstalled the Studio and re-installed it but have not updated to the latest because I do not know whether it will work or not :( Now I am back to business! – Vincy Mar 02 '17 at 17:41

    Confirmed. I have Ubuntu `16.04`, Android Studio `2.3.3` and adb `1.0.32`. The emulator goes offline at the end of `react-native run-android` when adb crashes with `*** buffer overflow detected ***: adb terminated`. This after stating `error: more than one device/emulator` (note: there is only one). – Arnold Schrijver Aug 20 '17 at 09:41

I had the same problem.

I opened the ADM before launching the emulator.Then, I launched the Emulator together with the app not before.

Now the emulator is online.

  • This procedure works, but then android debugger shows the emulator is offline. So I can not debug the app simultaneously. :( – orchidrudra Mar 24 '17 at 09:37

I have given up on trying to figure out what is going on with ADM. However, what I am currenly doing is, I have also installed the Canary version of Studio 3.x from here https://developer.android.com/studio/preview/index.html and everything works just fine with it. I can even pull the database from the device without having any problem. They both run side by side without having any issues on my Windows 7 work desktop.

The only downside of this, having to install both versions but as long as you have 16GB ram you should be fine. That is what I in my PC. Hope, this helps!
