If the emulator has started, that may mean adb is acting up. Not sure on windows, but on mac/linux I do the following:

<pre><code>adb kill-server
sudo adb devices

You could try that (get rid of the 'sudo' business).

I don't think you're waiting long enough. There's 3 stages to go through

<ul>
<li>Wait until the android logo disappears on startup (unless you've disabled boot animations)</li>
<li>Wait for the locked screen to come up.</li>
<li>Wait for the app to be actually installed onto the device (you'll get a message saying 'Installing nameOfApp on Emulator device #whatever')</li>
</ul>

This whole process will take anywhere from 3 - 15 minutes. To speed things up, make sure you leave the emulator ON then you just need to do step 3.

If you try to click Run again before this is all done, it will incorrectly assume no emulator is up and start up a new one.

You can also make sure your emulator is ok by selecting <code>Window -&gt; Android SDK and AVD Manager</code> and selecting <code>Virtual Devices</code>. You can even start a device up first (stages 1 and 2) without actually installing your app. You can also check the status of the device using DDMS (and make sure that it isn't actually installing your app and then silently crashing) by selecting DDMS at the top-right of Eclipse or <code>Window -&gt; Open Perspective -&gt; Other -&gt; DDMS</code>

Hope this helps.

blocks|key|842294|text|启动仿真器后，检查仿真器名称是否已反映在Eclipse->DDMS->Devices中。如果它被提到为“在线”，你可以只运行应用程序，它不会启动新的模拟器。如果显示为"Offline"，请转到"View+Menu“选项(设备窗口中的一个小向下箭头按钮)，然后重置adb。这将重新启动adb并使仿真器联机。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|842295|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

After starting the emulator, check the emulator name has been reflected in Eclipse->DDMS->Devices. If it is mentioned as "Online", you can just run the application and it wont launch new emulator. If it is mentioned as "Offline", go to "View Menu" option(a small down arrow button in Devices window) and reset the adb. This will restart adb and will make emulator Online.

best way to just kill the current running server

<pre><code>adb kill-server
</code></pre>

blocks|key|4841058|text|转到命令提示符，设置adb的存储路径，并发出以下命令:首先，通过发出命令adb+kill-server杀死adb，然后通过发出命令adb+start+-server(对于windows)启动adb，否则还有另一个选项，转到DDMS并重新启动adb。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4841059|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Go to Command prompt and set the path where the adb is stored and give the following command:
First kill the adb by giving the command adb kill-server
and then start the adb by giving the command adb start-server(for windows)
Otherwise there is another option Go to DDMS and restart the adb.

I do not believe what you are witnessing is a bug at all.

You probably do not need to restart the adb.

What is happening is this:

If the current emulator you are running does not fit the minimum SDK of project you trying to run. 
The Android SDK manager will run an emulator that does fit the minimum sdk requirement.

I'm busy learning how to build apps for Android, and I come across a very awkward problem.

When I run my application (with the green circle with the play-icon in it), it starts an Android emulator (like it should), but the application doesn't start once the emulator is booted. When I click the run-button again, it tries to start a second android-emulator. In the console-tab it gives the following messages:

<pre><code>[2011-11-07 20:57:15 - ScrollView Demo] Android Launch!

It's like Eclipse doesn't recognize the emulators it starts...
Weird thing is, sometimes it does recognize it, but most of the times it doesn't.

If it makes any difference: I'm running Eclipse IDE for Java Developers (Indigo Service Release 1) with ADT 15.0.0 on Win7 Home Premium 64bit
