title: Android SDK sources : Source code does not match bytecode
body: <p>SDK versions:<br>
  compile SDK version : 27<br>
  target SDK version : 27<br>
  min SDK version : 23<br>
  Samsung tablet SDK version : 25 (Android 7.1.1)  </p>
  
  <p>I have sources installed for SDK version 25 and 27, but when stepping into SDK code I get an error "Byte code doesn't match source code". The source file opened is for SDK version 25.</p>
  
  <p>This only happens for some android modules (android.widget, android.app) while others work fine (android.os).</p>
  
  <p>The app source also contains some legacy and deprecated features.</p>
  
  <p>Is there a way to<br>
  a) Find out what causes the mismatch or<br>
  b) Switch to decompiled source code</p>
