title: Error while building qt project for android
body: <p>I downloaded Qt Creator 3.3.0 Based on Qt 5.4.0 on Windows.
  Also jdk1.8.0_25, SDK (all updated), NDK-r10d, apache-ant-1.9.4.
  Set all necessary configurations.
  But when I try to build project I get an error:</p>
  
  <blockquote>
    <p>Error: Target id 'android--1' is not valid.</p>
  </blockquote>
  
  <p>As far as I understand it is about the API level. But where can I set it?</p>
