title: ngc: Error: Unexpected value 'ChartsModule' imported by the module 'AppModule'
body: <p>When compiling my ionic2 app for android, I get this error:</p>
  
  <p><code>ngc: Error: Unexpected value 'ChartsModule' imported by the module 'AppModule'</code></p>
  
  <p>If I only build it using <code>ionic serve</code> (bypassing angular2 AOT) then it builds and runs fine.</p>
  
  <p>I believe this error is due to <strong>the lack of metatdata.json file</strong> in the Telerik charts bundle (I only use the charts but I guess there's the same issue for other components). </p>
  
  <p>Other vendors have the same problem, see ticket here: <a href="https://github.com/angular/angular/issues/11262" rel="nofollow">https://github.com/angular/angular/issues/11262</a></p>
  
  <p>Could this be fixed ? </p>
