Answer 1

Check your Gradle file dependencies if there is dependency to icu4j remove it or if you are not using icu4j you can add

release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'),
                'proguard-rules.pro'
    }

in your build configurations to remove unused code from your application.
