title: cordova error unable to open URL: file:///android_assets/www/cordova_plugin.js
body: <p>I'm using PhoneGap first time and not succeeded in running it properly.</p>
  
  <p>I downloaded a project from a link given <a href="http://download.macromedia.com/pub/developer/phonegap/myfirstphonegapplugin_a.zip" rel="nofollow">here</a>. It's working properly but when i tried to use cordova-2.9.1 then nothing is working properly.</p>
  
  <p>What i tried, replaced the <code>assets/www/cordova-1.6.1.js</code> file with the new <code>phonegap-2.9.1\lib\android\cordova.js</code> of PhoneGap-2.9.1, which i downloaded from <a href="http://phonegap.com/install/" rel="nofollow">here</a>. And changed the JAR file too. The JAR is not in the downloaded cordova-2.9.1, i have created the JAR file from the given .java file inside <code>phonegap-2.9.1\lib\android\framework\src</code></p>
  
  <p>Here the code i added in <code>config.xml</code></p>
  
  <pre><code> &lt;feature name="HelloPlugin"&gt;
    &lt;param name="android-package" value="com.tricedesign.HelloPlugin"/&gt;
  &lt;/feature&gt;
  </code></pre>
  
  <p>plz help me find out the solution to my problem.</p>
