title: Using hashtable or SQL Lite in my android application
body: <p>Initially I use hashtable in my android application. The key point I love hashtable is it is able to store complex item such as: coordinate-->float[2], velocity-->float[2].</p>
  
  <p>But from many samples, using SQLlite table in android seems more efficient but it may only store all the values in one row defined by rowID. </p>
  
  <p>So can anyone enlighten me on this problem? using hash table or SQL lite is more feasible?
  Can hashtable keep the data if I exit the application?</p>
