PIMOB:2459 - Added moshi codegen dependency

Issue

Proposed changes

Context: Merchant issue Error: java.lang.IllegalArgumentException: No property for required constructor parameter #0 p0 of fun(kotlin.String, kotlin.String, kotlin.String, kotlin.String, kotlin.String?, kotlin.String?, com.checkout.tokenization.entity.AddressEntity?, com.checkout.tokenization.entity.PhoneEntity?)

Problem/Merchant issue: Starbuck is migrating from legacy Frames to the latest version. However, while migrating they use Dexguard to generate the signed apk. The problem is when they obfuscate their code using it, results in for the app not being able to find the network models from the SDK which are generated by Moshi using @JsonClass(generateAdapter = true). This annotation is doing the serialisation/deserialisation of the objects while processing network calls and we don't need to do it manual parsing. The main reason of the crash is that we are not using Moshi codegen reflection which has the functionality to not remove those generated classes during obfuscation instead we are using kotlin serialisation using Moshi.

References to understand the issues: Moshi developers introduce new improvements using moshi reflection library as codegen to not remove generated adapters during obfuscation. Reference Moshi PR

Trial and error solution: Initially we tried different solutions comparing this PR which were validated by me and Starbuck (reference app to reproduce the issue shared by a merchant). Explaining it, we have implemented manual the serialisation/deserialisation of network objects which does not take part in kotlin reflections and also adds runtime cost to perform it. Reference branch

Final solution: In this PR, we tried to optimise the code and extra parsing operations we were performing in the previous solution by adding a new library as codegen for reflection and updating the moshi version.

Test Steps

I have validated the below snapshot versions in the merchant sample app and it's working fine. Additionally, I will do full regression testing going forward. implementation("com.github.checkout.frames-android:frames-android:c8a870c")
