OkHttp Interceptors in Android
Notes: 06. Implement an Analytics Interceptor
Try creating an Interceptor that retries an API call if it fails just once.
Progressively, start moving network operations common to all API calls to an Interceptor.

Intro
When releasing apps to production, it is helpful to have analytics data. Analytics can help you learn more about your users as well as narrow down the scope when debugging an issue.
