title: INSTALL_FAILED_UPDATE_INCOMPATIBLE but app not installed
body: <p>I am getting an INSTALL_FAILED_UPDATE_INCOMPATIBLE error upon doing a</p>
  
  <pre><code>adb install MyPackage.apk
  </code></pre>
  
  <p>I did what all other posts out there suggest, namely an uninstall of the package with</p>
  
  <pre><code>adb uninstall com.company.package
  </code></pre>
  
  <p>(with appropriate substitutions for 'company' and 'package'), which reports
  'Success', but the install error still appears...</p>
  
  <p>In the adb logcat output I get</p>
  
  <pre><code>No content provider found for permission revoke: 
     file:///data/local/tmp/MyPackage.apk
  Package com.company.package codePath changed from 
     /data/app/com.company.package-1.apk to 
     /data/app/com.company.package-2.apk; Retaining data and using new
  Package couldn't be installed in /data/app/com.company.package-2.apk
  </code></pre>
  
  <p>Which suggests that there are still traces of a previous install left, but I cannot figure out how to get rid of those traces.</p>
  
  <p>Any ideas? The device is not rooted and I would like to keep it that way if possible.</p>
