Android studio doesn't recognize the running emulator-ThrowExceptions

Exception or error:

When I run my app from AndroidStudio 0.4.3 using Run I see Choose Device which has two sections choose a running device or Launch Emulator. I don’t have a running emulator at the moment so I click the ... to launch AVD manager and start an emulator. At this point I see that under choose a running device the emulator I just launched shows up but its listed as offline.

In the past the offline status went away when the emulator was fully up and running. However, now I’ve noticed that when the emulator is launched fully, it no longer appears in choose a running device.

I feel like I’m always playing cat and mouse game with android studio picking up the emulator. Is there a better way to do this? Am I missing something?

How to solve:

Disable and then Enable ADB Integration

In Android Studio go to

  1. Menu -> Tools
  2. Android
  3. Enable ADB Integration (should be checked, click to remove check)
  4. Enable ADB Integration (should not be checked, click to add check)

Run your app again. Emulator that was previously missing from Run dialog should be available to be selected upon which to run your app.

###

Try to kill the adb server and restart it.

Locate your adb binary (linux/osx) or adb.exe (windows) and do:

adb kill-server
adb start-server

this should fix your problem

Even if your problem still not solved then Restart emulator.

###

On Windows, running Android Studio with administrator permissions can help (in addition to restarting adb server).

###

Unchecking the “Enable ADB ” worked for me

###

Wipe Data and restarting emulator helped me, hope this helps to someone.
