title: Decompile Kotlin to JAVA
body: <p>I am a beginner at Android Studio , and I want the main activity to be on java not on kotlin . I tested some solution available on Stack overflow such as:<br>
  menu -> tools -> kotlin -> decompile kotlin to java </p>
  
  <ol>
    <li> Menu > Tools > Kotlin > Show Kotlin Bytecode </li>
    <li> Click on the Decompile button </li>
    <li> Copy the java code </li>
  </ol>
  
  <p>and always the Decompile button is disabled.</p>
