The connection to adb is down - android

I am trying to run an android application I build in the android emulator using eclipse , but every time I try I get the following error:
[2013-11-30 14:14:12 - MyFirstApp] The connection to adb is down, and a severe error has occured.
[2013-11-30 14:14:12 - MyFirstApp] You must restart adb and Eclipse.
[2013-11-30 14:14:12 - MyFirstApp] Please ensure that adb is correctly located at 'C:\<sdk directory>' and can be executed.
I tried adb kill-server and adb start-server, searched Stack Overflow , found this
and this, tried everything , but still can't get to start the application.
The AVD starts but the app doesn't start on AVD.
Then after some waiting,
[2013-11-30 14:26:54 - MyFirstApp] Failed to install MyFirstApp.apk on device 'emulator-5554!

Your error it self saying :You must restart adb and Eclipse.
Try this once:
Step1. Go to DDMS perspective
Step2. Click on emulator opened at Devices tab
Step3. Click view Menu on reset adb as shown bellow image
Step4. Restart Eclipse.
May it helps you.

Just restart your Eclipse and device or emulator which you are using for testing apps and go to task manager find adb.exe -> End Task.
You will not find any error after that.

Not able to install app on emulator

[2013-07-03 10:24:58 - SimpleAndroid] Failed to install SimpleAndroid.apk on device 'emulator-5554!
[2013-07-03 10:24:58 - SimpleAndroid] (null)
[2013-07-03 10:24:59 - SimpleAndroid] Launch canceled!
I have tried all solutions as given on the web and stackover flow which includes wiping all the user data on emulator startup
I have increased the ADB connection timeout to 30000 also. My emulator and sdk are of the same version. All my packages are installed perfectly as java is working fine
Please help someone
Run this command on command prompt..
adb uninstall <package-name>
then
adb install <package-name>
Close your emulator ,Got to your task manager , find adb.exe and end process. If there are multiple instances of adb.exe close all .
After you are done with this do a clean of the project and right click and run the project.
This should do the trick

My android emulator doesnt launch

I installed the Android Development Tool and created my first app but when I run the app, the emulator doesnt launch.The console reads:
[2013-06-18 14:36:57 - MyFirstApp] Android Launch!
[2013-06-18 14:36:57 - MyFirstApp] adb is running normally.
[2013-06-18 14:36:57 - MyFirstApp] Performing com.example.myfirstapp.MainActivity activity launch
[2013-06-18 14:37:19 - MyFirstApp] Launching a new emulator with Virtual Device 'AVD'
Unfortunately, it never launches. The following is what I have tried to do to solve the problem:
I created AVD both by graphical user interface and command line but it didnt run.
I tried to open task manager and stop the adb.exe process then run it again but no.
I tried to kill the adb server and restart it by command line but again no, didnt run.
I finally tried to launch the emulator on command line and this is what it says (directly translated): "a problem interrupted the program, trouble-free operation. Windows will close the program and notify you if a solution to the problem is available."
Please help.
After a long struggle, I decided to install a new Operating System. The emulator can now launch.

how to fix? I can't run my application its cancelled

I have always getting the below error while run my application.
I tried all solution through google. Still i didn't able to fix my solution.
I restart my eclipse and delete the AVD and create it again and done reset adb also.
Still in getting this error
Failed to install Final.apk on device 'emulator-5554!
(null)
Launch canceled!
I can't able to start my homescreen. What is the solution for this?
Try executing
adb kill-server
adb start-server
in command prompt from /platform-tools folder in your android-sdk.
Then try launching the application after you see *daemon started successfully*.

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

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
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
Fixed it adb kill-server followed by adb start-server

android timeout error

I have constructed my app and have tested it on the real device but for some reason it is timing out. I am not sure why.
Here is Error log:
[2012-05-29 09:49:42 - androidGUI] Android Launch!
[2012-05-29 09:49:42 - androidGUI] adb is running normally.

Try change the DDMS adb connect time out :
in Eclipse -> Windows -> Preference -> Android -> DDMS
Change the ADB Connection time out(ms) bigger whatever you want.
If it also the problem, you can try:
adb kill-server
adb devices
Then, refresh the device(s).
This is because the emulator is disconnecting from the DDMS of the eclipse...
so to reconnect it run the command
adb devices
which will restart the adb...
Hope it works
Try to change the ADB connection timeout. I think it defaults that to 5000ms and changed mine to 10000ms i was able to get rid of that problem. If you are in Eclipse, you can do this by going through Window -> Preferences and then it is in DDMS under Android.
Hope this will help
Are there by any chance spaces in the directory path to your APK. I have seen several people have this kind of trouble due to that. (Often the mistake is to put eclipse in Program Files and the workspace inside eclipse.) Try copying your apk file out of the workspace and to C: and upload it with adb push.
For me, the solution was to uncheck the "wait for the debugger to attach" in the development options of the device.
