hey @jehillert, thank you, we'll check it!

@marius-zilinskas-tg I had the same problem and simply changed the parent to FragmentActivity, and everything seems to work ok. Did you experience any problems with this approach?

hi @ttnisal, I believe it's an obfuscation issue as well, could you please try adding the rules from [here](https://github.com/google/gson/blob/main/gson/src/main/resources/META-INF/proguard/gson.pro)?

@ttnisal could you please also add some Adapty verbose logs around the error? but anyway, it totally looks like an obfuscation problem, not the SDK bug

Hi @ttnisal, do you have something like `proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'` on the same level as `minifyEnabled true`?

@ttnisal are those proguard rules above in the right `proguard-rules.pro` file? it should be on the same level as the `build.gradle` file that contains the lines from the above comment

@ttnisal by "same level" I meant same level in the project hierarchy, that would mean that you've chosen the right `proguard-rules.pro` `'{"a":"abe22e1e-77f9-468b-bc40-4783032b673d","b":"String","c":""}'` shows that this model have been obfuscated, but...

Hi @ttnisal > Are there any other library that can cause the obfuscation? I think no, it looks like only these two. > does the package @adapty/react-native-ui need any proguard...

@ttnisal could you please expand *com/adapty/internal/crossplatform/ui*? this is the package of that model from json you provided with obfuscated keys

@ttnisal suppose `AdaptyUiView` is not obfuscated, right?
