Cronet is the Chromium network stack made available to Android apps as a library. Cronet takes advantage of multiple technologies that reduce the latency and increase the throughput of the network requests that your app needs to work.
- Protocol support
- Cronet natively supports the HTTP, HTTP/2, and HTTP/3 over QUIC protocols.
- Request prioritization
- The library allows you to set a priority tag for the requests. The server can use the priority tag to determine the order in which to handle the requests.
- Resource caching
- Cronet can use an in-memory or disk cache to store resources retrieved in network requests. Subsequent requests are served from the cache automatically.
- Asynchronous requests
- Network requests issued using the Cronet Library are asynchronous by default. Your worker threads aren't blocked while waiting for the request to come back.
- Data compression
- Cronet supports data compression using the Brotli Compressed Data Format.
