Smash is Volley inspired networking library that's using OkHttp in its core.

Usage

Add Smash library to your project build.gradle

dependencies
{
    compile 'pl.appformation:smash:0.3.0'
}

Instantiate one shared SmashQueue object (e.g. in your Application class):

mSmashQueue = Smash.buildSmashQueue(getApplicationContext());

To request content of server as String do following:

String url = "https://github.com/appformation/smash";
SmashStringRequest request = new SmashStringRequest(SmashRequest.Method.GET, url,
        new SmashResponse.SuccessListener<String>()
        {
            public void onResponse(String response)
            {
                handleMyNiftyResponse(response);
            }
        }, new SmashResponse.FailedListener()
        {
            public void onFailedResponse(SmashError error)
            {
                showImpendingDoomError(error);
            }
        });

Request object looks definitely cooler with Retrolambda library:

SmashStringRequest request = new SmashStringRequest(SmashRequest.Method.GET, url,
    this::handleNiftyResponse, this::showImpendingDoomError);

Constructed request this way we now need to add to our SmashQueue:

mSmashQueue.add(request);

Adding custom headers to request:

SmashStringRequest request = ...
request.setHeaders(Headers.of("CustomHeader", "Value",
                              "AnotherHeader", "AnotherValue"));

Why another library?

Some of us like Volley library, it's easy to use and has superb extensibility with Request class, but recent removal of HttpClient in Marshmalow made library obsolete. We also don't like reactive programming. With this in mind came idea to rewrite Volley to use directly all of the internals of OkIo and OkHttp libraries.

What's different than in Volley

  • URL address can be modified, up to the point of reaching dispatcher queue
  • Source class from OkIo is used instead of InputStream
  • Ability to modify User-Agent field globally for all requests
  • Both listeners are obligatory in request constructor
  • To prevent class names conflicting with OkHttp all smash classes have Smash prefix

Things to do

  • Retry policy (for now default from OkHttp is used)
  • Authentication mechanism in requests
  • Moshi support (thanks to OkIo we can use Source class with Moshi)
  • Support for multipart/form-data upload
  • ... and last but not least, unit tests
