title: sencha android packaging error - undocumented parameter?
body: <p>My sencha config seems to be missing a parameter, can't figure out where it's being generated from the build. </p>
  
  <p>Executing <code>sencha package build config.json</code></p>
  
  <p>With the config as specified in the sencha docs the tool generates the command: </p>
  
  <p><code>android create project --target android-7 --name appname --activity STActivity --path apppath --package pkg</code></p>
  
  <p>which generates the errors </p>
  
  <blockquote>
    <p>Failed to create android project Failed to package application [ERROR]
    Error: Target id is not valid. Use 'android list targets' to get the
    target ids.</p>
