Crisp progurd rules for full mode

[rezafaraji93]

Would you please provide progurd rules for crisp?

I am using R8 full mode and ANR happens because of Crisp

Hi @rezafaraji93 and thank your for your feedback.

I didn't tested yet minification with R8 full mode as it was an experimental feature. However, I've just tested it and indeed it crashes... But this isn't due directly to our SDK but from Gson and Retrofit libraries. They miss to export proguard rules:

• R8 full mode - Gson rules
• R8 full mode - Retrofit rules

For Retrofit, from the 2.6.4 version we're using (to keep 4.4 compatibility) to the latest 2.9.0 release, they only export the following rules:

-keepattributes Signature
-if interface * { @retrofit2.http.* <methods>; }
-keep,allowobfuscation interface <1>

But more are needed according to their master branch, so the following ones should also be exported:

# Keep generic signature of Call, Response (R8 full mode strips signatures from non-kept items).
-keep,allowobfuscation,allowshrinking interface retrofit2.Call
-keep,allowobfuscation,allowshrinking class retrofit2.Response

And if Kotlin is used, this one should be exported also:

# With R8 full mode generic signatures are stripped for classes that are not
# kept. Suspend functions are wrapped in continuations where the type argument
# is used.
-keep,allowobfuscation,allowshrinking class kotlin.coroutines.Continuation

So we end up exporting these proguard rules:

# Gson
-keep class com.google.gson.reflect.TypeToken { *; }
-keep class * extends com.google.gson.reflect.TypeToken
# Retrofit
-keep,allowobfuscation,allowshrinking interface retrofit2.Call
-keep,allowobfuscation,allowshrinking class retrofit2.Response
# Retrofit, only if Kotlin is used
-keep,allowobfuscation,allowshrinking class kotlin.coroutines.Continuation

I commited a fix for this but while waiting a new release, you already can apply these rules for your project, it should work ;)

Fixed in 1.0.10 and released :)
