it is a bit confusing that adb.exe is just in the right path ...
the version of eclipse i use is Build id:
Eclipse Java EE IDE for Web Developers.
Version: Juno Release
Build id: 20120614-1722
my adt version is：
20.0.3
the error message i get from android console is as follows, why the error happens?
[2012-09-26 12:17:40 - android] Dx warning: Ignoring InnerClasses attribute for an anonymous inner class
(org.apache.commons.httpclient.HttpMethodBase$1) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.

[2012-09-26 12:17:48 - android] ------------------------------
[2012-09-26 12:17:48 - android] Android Launch!
[2012-09-26 12:17:48 - android] The connection to adb is down, and a severe error has occured.
[2012-09-26 12:17:48 - android] You must restart adb and Eclipse.
[2012-09-26 12:17:48 - android] Please ensure that adb is correctly located at 'D:\Tools\sdk-tools\android-sdk-windows\platform-tools\adb.exe' and can be executed.
what's more, once i start android emulator, i can find it using:
adb devices
but i cannot find it in adt's device view, why?
