Can we access your project?

  • I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

I am using the Adapty library as my payment processor. I got around the library bug by copying all variables and data types into my app so I can use it myself.

Adapty works for iOS no problem, and several days ago, it was also working for Android. As of today, there is an initialization issue on Android. It seems that during the build configuration ProGuard/R8 are altering the Adapty code in such a way that it prevents initialization. Here is the debug log:

Calling Adapty.identify()...
=== AdaptyError Caught ===
Error Code: 20
Error Message: Adapty was not initialized
Returning: AdaptyErrorStruct
=== ADAPTY DEBUG LOGS ===
Activation error: PlatformException(error, TypeToken must be created with a type argument: new TypeToken<...>() {}; When using code shrinkers (ProGuard, R8, ...) make sure that generic signatures are preserved., null, java.lang.IllegalStateException: TypeToken must be created with a type argument: new TypeToken<...>() {}; When using code shrinkers (ProGuard, R8, ...) make sure that generic signatures are preserved.

Hello!

There is a solution for this issue, but it requires a manual change in the Android folder. If you're deploying via GitHub or outside of FlutterFlow, you can resolve it by editing the android/app/proguard-rules.pro file and adding the following lines:

-keepattributes Signature
-keep class com.adapty.** { *; }

In the meantime, I’ve reached out to an engineering team member to get further guidance on how to proceed with this issue. I'll update you as soon as I have more information.

Thank you for your patience and understanding!

Just as an update, you have to add these rules in the proguard for it to work, the ones above were incomplete:

-keep class com.adapty.** { ; }
-dontwarn com.adapty.ui.*
-keepattributes Signature
-keep class com.google.gson.reflect.TypeToken { *; }
-keep class * extends com.google.gson.reflect.TypeToken

I am unsure if this is just for the flutterflow version in the Adapty Library, which seems pretty old compared to the most up-to-date version, or all versions of the Adapty SDK.

This does not solve the issue of it deploying from flutterflow though.
