Question

I\'m having a problem with emulator-5554, it keeps telling me it is offline.

When I do a adb devices from the command line it says

Answer 1

I finally solved this problem, I had to go to the Developer options from the Settings in the Emulator, then scrolled down a little, turned on the USB debugging. Instantly my device was recognized online, and I no longer faced that issue. I tried restarting android studio and emulator, killing adb process, but those did not work.

Answer 2

Try this ...

1. Close emulator if it Running.

2. Start Emulator again and wait for its online.

3. enter Command in commandprompt and press ENTER key : adb tcpip 5555

(Make sure that only One emulator running at a time.)

1. adb -s emulator-5555 emu kill

2. Press Enter Key....

3. Done.

4. check devices by command "adb devices" in cmd.

Answer 3

I tried everything but only this one works for my case: Use SDK manager, and reinstall the system image. Android Studio, click Configure, SDK Manager, Launch Standalone SDK Manager, Check all "Google APIs Intel x86* System Image", "Intel x86 Atom*System Image" and install. Then re-start Android studio.

You might have to reconfigure and wipe the virtual device with AVD Manager, make sure you choose x86 version.

Answer 4

If you are on Linux or Mac, and assuming the offline device is 'emulator-5554', you can run the following:

netstat -tulpn|grep 5554

Which yields the following output:

tcp        0      0 127.0.0.1:5554          0.0.0.0:*               LISTEN      4848/emulator64-x86
tcp        0      0 127.0.0.1:5555          0.0.0.0:*               LISTEN      4848/emulator64-x86

This tells me that the process id 4848 (yours will likely be different) is still listening on port 5554. You can now kill that process with:

sudo kill -9 4848

and the ghost offline-device is no more!

Answer 5

The "wipe user data" option finally solved my problem. just wipe user data every time you start the emulator. This always works for me! I use windows 8 x64 , eclipse

Answer 6

Simply delete and created gear avd again.It will work.
