Unable to have signed .apk file from Eclipse
<p>I am trying to upload my app in market place. for this i have tried to generate signed .apk file.
I have followed these step:
project>android tools> export signed application package
a window appears i have created new keystore in a new folder by giving location and password. keystore is successfully saved then i move forward, give alias details then gave  path to the  same folder where the keystore is present for .apk file. But the error i got is:</p>

<pre><code>[2012-09-09 10:34:03 - Dex Loader] Unable to execute dex: Multiple dex files define   Lorg/project/R$attr;
</code></pre>

<p>In my project workspace, bin folder i have found classes.dex file. I deleted that file then again repeated the same process but the error is same. When i deleted R file and regenerate it by clean the project. classes.dex again created. how to get rid of such error and have signed .apk?</p>

<p>Kindly help me. I will be very thankful.</p>
