I am looking for a light weight Bitcoin library for an Android app.
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.
I noticed BitcoinJ and recently a new addition called BitherJ (https://github.com/bither/bitherj) which looks promising.
I am wondering which is best to use. Anyone has experience with this and can give pros/cons on each?
