Two modules, three functions, no interface

The unit of the swap is a module, not a class. Two source modules share one package name and one file name, and each defines the same three top-level functions:

// adapted — reporting module
package com.example.crashreporting

fun configCrashReporting(applicationContext: Context, dsn: String) {
    ReportingClient.init(applicationContext) { options -> options.dsn = dsn }
}

fun reportCrash(throwable: Throwable) {
    ReportingClient.captureException(throwable)
}
