title: Importing project gave Unable to resolve target 'android-7'
body: <p>This app I completed around a year ago (!) but never launched it on the market place. I am trying to open it up in eclipse now to make some small modifications and work on the code a little bit. So I imported it and then found this weird "unable to resolve target" error. It's highlighting every class red in all my 'src' files. </p>
  
  <p>I've looked at a similar question which said to add the line to default.properties file. My project has a project.properties file which has the line: </p>
  
  <pre><code>target=android-7
  </code></pre>
  
  <p>Any advice how to get this to work? I could always start a new project and just copy all the src files but that would be pretty lame and time-wasting. </p>
  
  <p>One more comment - I'm developing on a new computer and I don't think I have the API level 7. Could that be the problem? I've gone into Window --> Android SDK Manager and the oldest available API it shows is level 8. But level 7 will mean I can target more devices I think so I'd like to go with that.</p>
  
  <p>Thank you for any help.</p>
