Android Emulator - offline to online mode

Question

Is there a way to bring android emulator from offline to online mode without closing AVD? I tried adb's 'kill-server', 'start-server' commands but this just seems to re-start adb server (adb.exe process), the emulator is still in offline mode and 'adb devices' still show 'offline' state.

Also can someone explain what exactly 'offline' mode of emulator means. In my case - Emulator (standalone), daemon process and ADB server - all seem to be running. Why is emulator state still offline?

Updating Question: I have tried 'adb reset' both from Eclipse & command line that does not solve the problem. Issue seems to be more with Emulator Memory. Per my analysis memory of emulator keeps increasing and after a limit (~470 MB in my Windows) if you try to do a adb reset - it brings the state of emulator to offline and no more adb commands work. (also no network calls seem to be working)

Answer 1

Use these commands from the command prompt it will help u

1.adb kill-server //kill all active server
2.adb start-server //start adb server
3.adb devices //check the list of active server
