okio
A modern I/O library for Android, Java, and Kotlin Multiplatform.
A utility library from Square that simplifies reading and writing files, network sockets, and byte data in Android, Java, and Kotlin projects, filling gaps left by standard Java I/O tools.
Okio is a library from Square that makes reading and writing data easier in Android, Java, and Kotlin projects. It was originally built as part of OkHttp, Square's widely used HTTP networking library for Android, and then extracted into its own project because the data-handling code was useful on its own.
The library fills gaps left by the standard Java tools for working with streams, files, and byte data. It provides cleaner APIs for common operations like reading from a file, writing to a network socket, or transforming data as it moves between sources and destinations.
The README for this project is brief and points to the project website for full documentation. Based on what is provided, this is a low-level utility library aimed at developers rather than end users.
Where it fits
- Replace verbose Java stream boilerplate with Okio's cleaner API for reading files or writing to a network socket in an Android app.
- Transform data as it moves between sources and destinations using Okio's composable buffer and pipe abstractions.
