Android Development on Eclipse: Always opens new emulator - android

This should be a really simple one. I am doing the Hello Android tutorial and I was able to get my app to install into the emulator. However, when I go to run again (with no changes) the eclipse environment insists on launching a new emulator instead of connecting to the existing one. How do I fix that? My development environment is a Mac Mini running Mac OS 10.6.8.
Thanks.
New Update:
I have found the answer:
First I read this [question linked above by Mangusto][1]
Use same android emulator everytime
Then I realized that what one really needs to do, if the emulator is opening and initializing slowly, is to start the emulator, wait for it to initialize, and then attach to it the manual way described in the link above. Automatic does not work if your emulator is starting slowly as it disconnects as I described in the update below.
Thanks for the responses.
Update:
Below is the print out from eclipse (I tried to link image but could not due to my user level. I need reputation level of 10 or more). I had already tried the suggestion below about automatic vs manual. I think the issue is that while the apk file was installed it did not automatically launch in the emulator. Therefore, eclipse disconnected from the emulator. I was able to see my application by navigating to the apps within the android emulator.

Its because your application Target mode has set to manual. To solve :
Right Click on your project-> Run as -> Select Run Configurations ->
In that select Target Tab ->Select Automatic instead of manual
Click on Apply and run.
Now your app doesn't prompt for a device.
For a reverse case Select Manual.
Hope it helps.

Go to DDMS Perspective and if you can't see any emulator device on the list, Find the "View menu" dropdown on the "Devices" window on the left, and click Reset ADB.
After adb restarted it should be able to show all of your devices again.

Me also had the same problem.First of all clean your project.Take the DDMS mode in the eclipse .Here you are able to handle the devices in the emulator.There you can see the emulator control.From there select your device and run it.Hope it will solve your problem.

I had BlueStacks android app player installed. Its an application that runs on mac and pc allowing you to emulate android. Looks like it uses the android emulator under the covers. To uninstall on mac, go to Library>bluestacksplayer and uninstall app ... .solved the emulator 5554 problem.

Problems launching a virtual machine using the android avd manager [duplicate]

I have installed and set up Eclipse and the plugin ADT in order to work with Android SDK. So far so good. But when I try to launch a VM(virtual Machine) for any android platform that I choose (for example: android 3.2) I just get the skin launched together with a keyboard console and phone buttons, it seems to boot up to a state and then does nothing but displays the android logo on the main vm screen and that's all it does - no more!, no VM functionality!, what's going on? Have I missed out some step? Please help...
Have been waiting sometimes over 10 mins in each case for the emulator to start.
I launched/ran an Android project test sample; 'hello world' from the eclipse environment after installing the ADT plugin for Android These are the error messages I had displayed in the console ddms:

Do you Run your project or only start an emulator? After starting emulator, click Run button and select "Run as Android project".
I am not sure how long you waited, but starting the emulator the first time (before you have a snapshot) can take quite a long time. Depending on you hardware it can take more than 10 minutes to launch.
I had a similar issue which was solved by creating a new emulator and running it. You can check progress in Devices view through DDMS. Sometimes, this problem may occur when a snapshot enabled emulator hangs because of error, which can be solved by starting the emulator with user data wiped.
Emulator thread automatically cuts off if for some time you have not done any activity on it..
so.. keep running your app to keep emulator on LIVE!
My advice - if you having an android phone.. please usb debug it and Debug your application on your phone... You will feel relieved from the long durations of the emulator........ to run!! :)

I’ve read posts on similar problem. I’ve tried many suggested solutions including restarting Eclipse, rebooting and restarting eclipse, creating a new project in eclipse, starting emulator first with “wipe user data” box checked, increasing the emulator time-out period from 5000 to 20000, unlocking emulator by clicking and dragging mouse, clicking Menu and Home buttons on emulator, and running the Layout version. Nothing worked. I’m using Android 4.0 AVD and Eclipse Build id: 20110916-0149 and the latest JDC on a Dell Inspiron 1501 laptop.
It’s hard to believe Google would make this discouraging example as the first impression new users experience. Hopefully someone can help.
When you have the "Failed to install HelloAndroid.apk on device 'emulator-5554!", try to wait some seconds,
dont close the VM and
reclick on "Launch Buton"
When you create a new Activity project, it effectively creates a Hello World app. Create a new project. Don't modify it. Just run it. If you don't see a Hello world message, check your install.

couldnt it be I have a bad configuration...?
wait for the emulator to setup completely and then test your app. Also, I would leave you AVD open so you dont have to wait so long everytime you run your application.
When it shows the red writing, don't close anything - leave it there and then press the run button again. Worked like a charm.
I was facing the same problem but i tried changing the ADB connection timeout. I think it defaults that to 5000ms and I changed mine to 10000ms 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.
Try this: create another emulator in AVD Manager and try to run your application in the new emulator.
Hope this might help you
You may need to increase the device ram size. For some Honeycomb AVDs at least, the default of 256 is insufficient, and caused me the same problem. Try at least 512.
Go to window and preference and increase the ADB connection time out(ms) which is 500 by default. Also change the base local debugger port to more than 9000 in my case it worked.
See Related post
This worked on Linux for me:
Run Emulator (Wait for the home screen of the Emulator to load)
Click Window > Open Perspective > DDMS
In Devices Panel, click on drop down menu > Reset adb
Run project
Valen answer is correct although its nice to know when to start running the app and when is not ok to start the app.Open the devices perspective. The next time you want to run an app first open the 'Android virtual device Manager' and run your avd then click on the device perspective and watch your emulator processes one by one firing up.. as soon this is done (its not fast you have to wait .. but at least you have some idea of whats going on .... a progress bar would be ideal for this place), click on your project and run as android app. On the devices perspective one more process will appear with the name of the package of your app. As soon as this happen your app is running on the device and it can be tested.
I have noticed this error when the emulator has not loaded fully, "android" is flashing on your screen. In other words, it is not yet ready for the application to be installed.
Just wait till you see that the emulator is fully ready, meaning the "android" has vanished and the device screen is visible on the emulator. Now run it and the application loads smoothly.
Restart ADB server from DMOZ

Any advice on what might be going wrong would be greatly appreciated. I've found lots of posts (here and on other forums) that seem to indicate the NSQuickDrawView vs. Quartz warning seems to be a problem across the board but doesn't have a solution yet. I'm more concerned with the "emulator-5554 disconnected..." bit and the fact that I can't seem to run any apps in the emulator. Any other info I can provide which would be helpful? Any insight?
Thanks in advance for your time!
I guess you need to reset your adb after launch the emulator. In eclipse, go to window -> show view -> other -> device(under android folder).
In the device view, find and reset adb. Then run your apps.
