Upgrading Android API from 28 to 29

Noticed JSON that was returned from a service getting modified by ProGuard after updating the API target version from 28 to 29. We’ve temporarily reverted to 28 to keep our build stable. Please point out an article that addresses this topic?

ProGuard might requires some additional configuration when it comes to serializing classes. You can add some additional -keep rules for these classes as described in detail here: https://www.guardsquare.com/en/products/proguard/manual/examples#serializable
