title: Are there any easy-to-understand and working tutorials for JBox2D?
body: <p>I am looking for some beginner tutorials for the newest release of JBox2D. The ones I have found are all outdated. If possible a tutorial on how to apply the whole thing on android would also be good. I am simply trying to make some walls that the player cant go through and apply some gravity.</p>
  
  <p>Thanks in advance.</p>
