title: Unity build apk Failure INSTALL_PARSE_FAILED_NO_CERTIFICATES
body: <p>I develop Unity app for Android and iOS. When I make build in Unity on <code>Android Platform</code> → <code>Player settings</code> → <code>Publish Settings</code> add keystore and pick <code>Key Alias</code>. 
  After that I have been opening <code>Profile or debug APK</code> in Android Studio and when I run app I have an error</p>
  
  <pre><code>Installation failed with message INSTALL_PARSE_FAILED_NO_CERTIFICATES: Failed to collect certificates from /data/app/vmdl1775631111.tmp/base.apk: Attempt to get length of null array.
  It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.
  </code></pre>
  
  <p>What can be help me?</p>
