Working POST Multipart Request with Volley and without HttpEntity

Question

This is not really a question, however, I would like to share some of my working code here for your reference when you need.

As we know that HttpEntity

Answer 1

I found a wrapper of the original volley library which is easier to integrate for multi-part requests. It also supports uploading the multi-part data along with other request parameters. Hence I am sharing my code for the future developers who might run into the problem that I was having (i.e. uploading multi-part data using volley along with some other parameters).

Add the following library in the build.gradle file.

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

Please note that, I removed the original volley library from my build.gradle and used the above library instead which can handle both multi-part and normal requests having similar integration technique.

Then I just had to write the following class which handles the POST request operation.

public class POSTMediasTask {
    public void uploadMedia(final Context context, String filePath) {

        String url = getUrlForPOSTMedia(); // This is a dummy function which returns the POST url for you
        SimpleMultiPartRequest multiPartRequestWithParams = new SimpleMultiPartRequest(Request.Method.POST, url,
                new Response.Listener() {
                    @Override
                    public void onResponse(String response) {
                        Log.d("Response", response);
                        // TODO: Do something on success
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                // TODO: Handle your error here
            }
        });

        // Add the file here
        multiPartRequestWithParams.addFile("file", filePath);

        // Add the params here
        multiPartRequestWithParams.addStringParam("param1", "SomeParamValue1");
        multiPartRequestWithParams.addStringParam("param2", "SomeParamValue2");

        RequestQueue queue = Volley.newRequestQueue(context);
        queue.add(multiPartRequestWithParams);
    }
}

Now execute the task like the following.

new POSTMediasTask().uploadMedia(context, mediaPath);

You can upload one file at a time using this library. However, I could manage to upload multiple files, just by initiating multiple tasks.

Hope that helps!
