Please anyone have any idea about this error then please inform me. Thanks in Advance.

Answer 1

Try to add -keep class io.grpc.** {*;} to your proguard configuration. It should work. There haven't been any crashes since I added it. Will be testing further.

Answer 2

Note Am Using Flutter, So this should work for Both Java/Kotlin Android and Flutter

After spending several hours, I fix it by

1

check if proguard-android.txt or proguard-rules.pro exist in Path yourproject/Android/app

2

If they exist, copy below config, If they do not, create seperate files for them including that same name (proguard-android.txt and proguard-rules.pro) at the Path i mentioned

3 (Config lines)

   -keep class io.grpc.** {*;}
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

Paste that above code inside the two files.

4 (Let your myproject/Android/app/build.gradle see them by adding this line)

 buildTypes {
    release {
        // TODO: Add your own signing config for the release build.
        // Signing with the debug keys for now, so `flutter run --release` works.
        signingConfig signingConfigs.release //If in debug, change release to debug

        minifyEnabled true
        useProguard true
        shrinkResources true

        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' //I add this line...
    }
}

Clean your project and run or generate your APK.
