title: onAttach method crossed in Android Studio 2.3.3
body: <p>I am new to android and I have been learning android from Bucky`s tutorials from youtube. I am using android studio 2.3.3. I am learning fragments and I have to use an overridden method by the name of "onAttach()",</p>
  
  <p>Whenever i go for this method, its always crossed. Why is it so? Anyone?</p>
