It was developed because there is an absence in Android SDK, of a networking class capable of working without interfering with the user experience.

Volley is a networking library for Android that manages network requests. It bundles the most important features you’ll need, such as accessing JSON APIs, loading images and String requests in an easier-to-use package.

Secondly, which is better volley or retrofit? Volley can provide fine grain control over caching strategy, but its harder to configure caching than Retrofit. Retrofit relies on OkHttp, which relies on Okio which effectively makes this library huge compared to a basic configuration of Volley. If size is an issue, Volley is a better bet.

Besides, what is request queue in volley?

A request dispatch queue with a thread pool of dispatchers. Calling add(Request) will enqueue the given Request for dispatch, resolving from either cache or network on a worker thread, and then delivering a parsed response on the main thread. Cancels all requests in this queue for which the given filter applies.

Does volley use OkHttp?

Volley by default uses as transport layer the Apache Http stack on Froyo and HttpURLConnection stack on Gingerbread and above. Nowadays there’s no many reasons to use those anymore and the good news is Volley allow us to easily set up OkHttp as its transport layer.
