title: Android - How to make the phone vibrate to the music playing
body: <p>I am new to Android development. I want to make an app that is essentially a music player but the phone can vibrate to the beat of the music playing. I remember the earliest Nokia phones had this feature, I want to recreate this for fun. </p>
  
  <p>My question: is this possible as an Android app? If so, what are the general approaches? 
  Do I have to analyse the sound patterns of the song then alter the vibration intensity? </p>
  
  <p>Thanks! </p>
