Emulator-5554 disconnected! Cancelling 'activity launch'! Tried to resolve with cmd commands but still not working

Question

I am getting this error, I tried to resolve it but still it is not working.I have tried "adb kill-server" and adb start-server and also emulator -avd emulator_name -wipe-data.

I have attached the screen shoot of cmd.

I just want to run my application, but after "Waiting for HOME ('android.process.acore') to be launched." I got emulator-5554 disconnected error, I searched on net and from following link I tried commands

HelloAndroid]emulator-5554 disconnected! Cancelling 'com.example.helloandroid.HelloAndroid activity launch'!

I tried to reset the adb but got following error:

[2012-08-06 10:12:38 - DeviceMonitor] Adb connection Error:An existing connection was forcibly closed by the remote host

[2012-08-06 10:12:39 - DeviceMonitor] Connection attempts: 1

Now, I have tried following solution that wipes user data but I do not want it.My applications need to interact with each other , with following solution it is not possible because now, I need to wipe data before running each application..:(

Select & Right Click on Android Project
Run Configurations
Go to tab Target 
Enable option Wipe User Data on Emulator launch parameters
Run Application

enter image description here

your question is not clear ,will you tell me what do you want? — skt, Aug 06 '12 at 05:13
Try to restart your eclipse. And,just try whatever you need.. — Praveenkumar, Aug 06 '12 at 05:27
I restarted eclipse many times.... Last time I faced this problem then it was resolved by adb kill and start server command — blackfyre, Aug 06 '12 at 05:31
Are you running more than one instance of eclipse, because that can mess with the adb server? — MikeIsrael, Aug 06 '12 at 05:47

If you use Eclipse just go to Windows - Show View - Device. There is small triangle Show menu. Press and choose reset adb. Wait a little bit and run your project again.

What I did is go to the Android Virtual Manager (AVD) and edit Memory Options: like adjusted Ram from 15 to 30 and VM Heap from 16 to 32. Since then the "emulator: 5554 diconnected! Cancelling ..." never scared me till I shut it down. It works for me, though.

I resolved it by following these steps,

Run Emulator
Keep the Emulator, (no matter same error occurs)
Make Sure the Home Screen of Emulator is appeared
go to Window -> Show Perspective -> DDMS --> In Devices Panel -> on Corner Drop Down Menu
Reset adb

I Hope it helps
