title: Android App Crawler not working -> Permission Denial failure
body: <p>I was trying to run app crawler locally in order to test robo scripts created in Android Studio. </p>
  
  <p>I followed this handy article (<a href="https://android.jlelse.eu/test-robo-scripts-locally-useful-for-firebase-test-lab-pre-launch-reports-41da83d5769f" rel="nofollow noreferrer">https://android.jlelse.eu/test-robo-scripts-locally-useful-for-firebase-test-lab-pre-launch-reports-41da83d5769f</a>) and ran into an issue where the crawler just said crawl started and crawl finished immediately. I couldn't find any answers on google for this issue. </p>
  
  <p>Here's the error from the logs: </p>
  
  <blockquote>
    <p>Permission Denial: starting instrumentation
    ComponentInfo{androidx.test.tools.crawler/androidx.test.tools.crawler.CrawlMonitor}
    from pid=3778, uid=3778 not allowed because package
    androidx.test.tools.crawler does not have a signature matching the
    target androidx.test.tools.crawler.stubapp</p>
  </blockquote>
  
  <p>I finally figured out a solution so I'm putting this question out to help those who might have been stuck like me. Sounds like some people had the same issue in this question (<a href="https://stackoverflow.com/a/58631206/13071692">https://stackoverflow.com/a/58631206/13071692</a>)</p>
