Option 1 : Volley
Android 1.6 (API Level 4) or higher
Volley's benefits :
- Automatic scheduling of network requests.
- Multiple concurrent network connections.
- Transparent disk and memory response caching with standard HTTP cache coherence.
- Support for request prioritization.
- Cancellation request API. You can cancel a single request, or you can set blocks or scopes of requests to cancel.
- Ease of customization, for example, for retry and backoff.
- Strong ordering that makes it easy to correctly populate your UI with data fetched asynchronously from the network.
- Debugging and tracing tools.
Option 2 : OkHttp
OkHttp supports Android 2.3 and above. For Java, the minimum requirement is 1.7.
Some of the features listed in its documentation :
- HTTP/2 and SPDY support allows all requests to the same host to share a socket.
- Connection pooling reduces request latency (if SPDY isn’t available).
- Transparent GZIP shrinks download sizes.
- Response caching avoids the network completely for repeat requests.
