Migrate to 2.0.0

In version 2.0.0 we updated the Gini Bank API Library to version 2.0.0 which removed dependency on Bolts and Volley. Bolts was replaced with kotlin coroutines which is part of the kotlin standard library. Volley was replaced with Retrofit2, a more popular and elegant networking library built upon okhttp3.

The breaking changes affect only the Gini Bank API Library. If you are interacting with it directly, then please consult the Gini Bank API Library’s migration guide for details.
