title: HashMap Alternatives for Android Application
body: <p>I am having OOM issues with java.util HashMap so I am looking for memory friendly HashMap alternatives to standard Java Hashmap. I tried Trove and it improved a little but still ends up with OOM from time to time. I can accommodate some speed loss if memory is efficient. </p>
  
  <p>I am not looking for a DB. File-based HashMap implementations are also fine as long as they are working offline. I am storing primitives like int and byte.</p>
  
  <p>Also, please indicate if you had any experience and how much improvement you had in terms of memory.</p>
