Hi @aaa59891, that error message is from okhttp3 in android, it could be caused for reflection in okhttp library didn't success. Can you try upgrade the okhttp version and try again? They may already have a fix in new version.

btw @Abhishek01039 yeah, Amplitude-Flutter is free to use. This is developer docs for reference.

We're having the same issue. Is there currently any workaround for this? @qingzhuozhen

Here are a couple of workarounds that worked for me. Both involve editing the android/app/build.gradle file

1. Set the compileSdkVersion to 28
2. Under dependencies, add the latest version of the okhttp package

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation "com.squareup.okhttp3:okhttp:4.9.1"
}

Hello @aaa59891
Is Amplitude-Flutter is free?
How you setup the server ?

Thanks

Hello, this is likely related to OkHttps use of reflection. See this answer for more information about OkHttp version and Android API version.
