Additional information

I have investigated that your lib get conflict with this lib muxstats. can you tell me that which part of library maybe conflict, and some idea for resolve it.

I had update lib to def amplify_version = "2.15.2"

Hi @sontnfabbi, can you elaborate on what conflict you are seeing? Is there a build time issue, or a run time time issue? Are you suggesting that when mux-stats-sdk-media3 is added to the application then the problem in the issue description occurs, but if it's not added then Amplify behaves correctly?

@mattcreaser It's a runtime issue, an error occurs when building a release with minifyEnabled true.
When not using MUX, everything works fine.
When I configured the debug and release buildTypes to be the same, the error still only occurred with the release build.

[mattcreaser]

Thanks for the additional info @fabbi-hoanh. It almost sounds like there is some sort of dependency conflict, although it's interesting that it only manifests with release builds. We'll need to investigate this issue.

@mattcreaser
I added this to proguard and it worked.
-keep class org.json.** { *; }
-dontwarn com.google.ads.interactivemedia.v3.api.**

[mattcreaser]

Thanks for the update @fabbi-hoanh, appreciate the investigation. I'm still unsure about the cause of this issue but I'll look into whether we should have keeping org.json as a consumer rule for Amplify.
