Android R Cannot be resolved issue
<p>I have just been working on my android project in eclipse and all of a sudden this error appeared, my manifest file matches the name of my application etc.............!</p>

<p>What I have noticed is that that the auto generated Java files are missing from the gen folder its completely empty now.</p>

<p>orginally I had to create a default.properties file as there wasn't one present and it was working fine uptil the point i tried to add a button into one of my xml files. Tried to clean project too and that hasn't resolved the issue either.</p>

<p>Any ideas?</p>
