If content of your ZIP consist of 1 file (for example, zipped content of HTTP response), you can read text content using Kotlin as follows:

@Throws(IOException::class)
fun InputStream.readZippedContent() = ZipInputStream(this).use { stream ->
     stream.nextEntry?.let { stream.bufferedReader().readText() } ?: String()

val inputStream: InputStream = ... // your zipped InputStream
val textContent = inputStream.readZippedContent()
