Finding all calls to a specific android sdk level
<p>I need to port an Android app to an older version. That is, the app now runs in 4.0, but not in 2.2, so I need to find all API calls incompatible to 2.2 and do a workarround.</p>

<p>Is there any tool to do that easilly? That tool whould be theorically simple, it just had to find all function calls and check it's "@since" attribute, but I can't find one.</p>

<p>I wonder how other people do that. If I don't find this tool I may do it, but I don't know how much time will I have, or even if I'll have the needed skill.</p>
