java - Securely Storing Keys in Android Keystore -


i making android application communicates server. i'm using token based authentication on server, , pass information client server, using asymmetric encryption.

this how process goes

  1. generated public , private key exists before hand
  2. public key used encrypt information, , passed server client
  3. app uses private key decrypt information

however, not know how securely store private key in keystore. if store during runtime, key out in code, , if send private key during rest connection, there's no point of having encryption because hacker can find both keys. can me on creating best possible solution? thx in advance!
