title: Error while Installing APK app-debug.apk does not exist on disk
body: <p>Hopefully someone can help.    Have an APP that I have been working on for awhile.   Compiled it earlier, no issues, and ran a debug on an attached device.</p>
  
  <p>When I came back to AndroidStudio today, was prompted for an UPDATE to studio as well as a Gradle update.   Ran both updates as listed... no errors during the update.</p>
  
  <p>Restarted AndroidStudio and "Run APP" once again.    Went through the Gradle Build as normal... then received an error when installing to the attached device....</p>
  
  <p><strong>Session 'app': Error Installing APK</strong></p>
  
  <p>Checking the <code>RUN</code>, I am getting:</p>
  
  <pre><code>The APK file C:\Users\Pete&amp;apos;s PC\AndroidStudioProjects\&lt;myapp&gt;\app\build\outputs\apk\app-debug.apk does not exist on disk.
  
  Error while Installing APK
  </code></pre>
  
  <p>That file exists with the current build date/time.</p>
  
  <p>Doing some searching, people mention CLEAN / REBUILDS in various steps, tried them all.   Tried exiting AndroidStudio too.   Went to the device's Developer Options and Revoked USB Debugging Authorizations... then reapproved them when prompted.   Also tried SYNC.</p>
  
  <p>Nothing works.</p>
  
  <p>It's even more frustrating because I didn't change one line of code, one setting, or anything.   It was a prompted AndroidStudio/Gradle update.  Uggghhh!!!</p>
  
  <p>Any other suggestions... I am dead in my tracks right now.</p>
