title: What does "Failure [INSTALL_FAILED_OLDER_SDK]" mean in Android Studio?
body: <p>I got this <strong>Froyo</strong> (2.2) device that I am using to make an app.
  When I try to run the app directly to the device it shows an error saying</p>
  
  <pre><code>pkg: /data/local/tmp/com.example.HelloWorldProject
  Failure [INSTALL_FAILED_OLDER_SDK]
  </code></pre>
  
  <p>and in another window there's an error saying</p>
  
  <pre><code>Unable to attach test reporter to test framework or test framework quit unexpectedly
  </code></pre>
  
  <p>What seem to make the said errors?</p>
