We are utilizing CCAvenue app for android. You have to ask for the Android Integration Kit, however, your test account authorization, for example, MerchanId, Access Code, Encryption Key, from CCAvenue then you can do a "Consistent" integration with your Android App. Next, you should take this information stream: 

  1. Demand for payment choices from Mobile App to CCAvenue 
  2. JSON information with payment choices returned 
  3. Demand for encryption key from Mobile App to Merchant server 
  4. Demand for encryption key from Merchant server to CCAvenue 
  5. Dynamic encryption key returned 
  6. Encryption key sent from Merchant server to Mobile App 
  7. Exchange with scrambled information sent from Mobile App to CCavenue 
  8. Handled exchange status came back to Merchant server 
  9. Exchange status pulled by Mobile App 

Expectation this makes a difference!
