title: why is sliding drawer in android deprecated in API 17?
body: <p>I am new to android app development. Using API19 in android studio 1.2. I found sliding drawer attractive to use in my app. But when I used it in design layout, i got to know that it is deprecated. Hint says it is unsupported and use your own implementation.</p>
  
  <p>Why was it deprecated  ?
  Can I still use deprecated API without any issues ?
  If not, how can i implement feature similar to sliding drawer from UI perspective ?</p>
