VolleyPlus

VolleyPlus library Project improvements to Volley along with full image caching.It involves using RequestQueue, RequestTickle and Request.

• RequestQueue - Dispatch Queue which takes a Request and executes in a worker thread or if cache found its takes from cache and responds back to the UI main thread.
• RequestTickle - A single class which takes a Request and executes in same thread or if cache found its takes from cache and responds back to the same thread. Mainly useful in sync operations where you want to perform operations sequentially.
• Request - All network(HTTP) requests are created from this class. It takes main parameters required for a HTTP request like
  • METHOD Type - GET, POST, PUT, DELETE, HEAD, OPTIONS, TRACE, PATCH
  • URL
  • Headers
  • Parameters
  • Retry Policy
  • Request Priority (RequestQueue)
  • Request data (HTTP Body)
  • Request Cancellation
  • Response Caching
  • Successful Response Listener
  • Error Listener
  • Progress Listener (for few Request types)

VolleyPlus Provides variety of implementations of Request.

• StringRequest
• JsonRequest
• JsonObjectRequest
• JsonArrayRequest
• GsonRequest
• GZipRequest
• MultiPartRequest/SimpleMultiPartRequest

    SimpleMultipartRequest request = new SimpleMultipartRequest(Method.POST, apiUrl, mListener, mErrorListener);
    request.addFile("photo", imagePath);
    request.addMultipartParam("body", "text/plain", "some text");

    RequestQueue mRequestQueue = Volley.newRequestQueue(getApplicationContext());
    mRequestQueue.add(request);
    mRequestQueue.start();

• DownloadRequest
• ImageRequest

VolleyPlus has also very powerful image caching SimpleImageLoder.

• DiskLruBasedCache based on DiskLruCache for Level2 (L2) cache
• Supports NewtworkImageView usage with SimpleImageLoader
• Can also update the cache
• Provides option to flush, close and clear the cache in both L1 and L2 cache
• Supported types of Image Caching
  • Network Caching
  • Resource Caching
  • File Caching
  • Video Caching
  • Content URI Caching

Usage

RequestQueue

RequestQueue mRequestQueue = Volley.newRequestQueue(getApplicationContext());

StringRequest stringRequest = new StringRequest(Request.Method.GET, url, new Response.Listener<String>() {
    @Override
    public void onResponse(String response) {
    	....
    }
}, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
    	....
    }
});

mRequestQueue.add(stringRequest);

RequestTickle

RequestTickle mRequestTickle = VolleyTickle.newRequestTickle(getApplicationContext());

StringRequest stringRequest = new StringRequest(Request.Method.GET, url, null, null);
mRequestTickle.add(stringRequest);
NetworkResponse response = mRequestTickle.start();

if (response.statusCode == 200) {
	String data = VolleyTickle.parseResponse(response);
	....
}
else{
	....
}

SimpleImageLoader

ImageCacheParams cacheParams = new ImageCacheParams(getApplicationContext(), "CacheDirectory");
cacheParams.setMemCacheSizePercent(0.5f);

SimpleImageLoader mImageFetcher = new SimpleImageLoader(getApplicationContext(), R.drawable.holder_image, cacheParams);
mImageFetcher.setMaxImageSize(300);
....

mImageFetcher.get(url, image_view);

OR

network_image_view.setImageUrl(url, mImageFetcher);
network_image_view.setDefaultImageResId(R.drawable.holder_image);

Quick Start

Volley is available as an AAR, so you just need to add the following dependency to your build.gradle.

buildscript {
    repositories {
        jcenter()
    }
}
...

dependencies {
     compile 'dev.dworks.libs:volleyplus:+'
}
...
