title: Recommeneded light weight Bitcoin library for an Android app
body: <p>I am looking for a light weight Bitcoin library for an Android app.</p>
  
  <p>I basically need a Bitcoin library that lets me create a private/public key pair (or preferably a wallet with keys that can be serialized). To be able to set the most appropriate fee for a transaction and submit it to the Bitcoin network from a Android app.</p>
  
  <p>I noticed BitcoinJ and recently a new addition called BitherJ (<a href="https://github.com/bither/bitherj" rel="noreferrer">https://github.com/bither/bitherj</a>) which looks promising.</p>
  
  <p>I am wondering which is best to use. Anyone has experience with this and can give pros/cons on each?</p>
