title: How to use the latest Android SDK Documentation offline
body: <p>I know it has been asked <a href="https://stackoverflow.com/questions/42893969/how-to-use-android-sdk-documentation-offline">again</a> and <a href="https://stackoverflow.com/questions/21739872/android-sdk-api-19-kitkat-offline-documentation">again</a>, but I can't find any way to work offline (on a plane) with the latest API level offline documentation (29).</p>
  
  <p>Is there any official or unofficial way?</p>
