Including in your project

OptimusHTTP is available in the Jcenter, so getting it as simple as adding it as a dependency

implementation 'com.github.nisrulz:optimushttp:{latest version}'

where {latest version} corresponds to published version in Download


  • Setup your SERVER url

    String SERVER = "http://uinames.com/api/";
  • Create an instance of the OptimusHTTP class

    OptimusHTTP client = new OptimusHTTP(context);
  • Next if in debug stage, enable logs

  • Define parameters to be sent with the request

    ArrayMap<String, String> params = new ArrayMap<>();
    params.put("email", "abc@abc.com");
    params.put("pass", "abc");
  • Define configurations for the request

    • Type of Method : POST/GET
      • POST Request java client.setMethod(OptimusHTTP.METHOD_POST);
      • GET Request java client.setMethod(OptimusHTTP.METHOD_GET);
      • PUT Request java client.setMethod(OptimusHTTP.METHOD_PUT);
      • DELETE Request java client.setMethod(OptimusHTTP.METHOD_DELETE);
    • Type of Mode : PARALLEL/SEQ
      • Parallel Request java client.setMode(OptimusHTTP.MODE_PARALLEL);
      • Sequential Request java client.setMode(OptimusHTTP.MODE_SEQ);
    • Setup timeout values (optional, default is 10s)
      • Connect Timeout java client.setConnectTimeout(10 * 1000);
      • Read Timeout java client.setReadTimeout(10 * 1000);
    • Setup content type (optional, deafult is CONTENT_TYPE_FORM_URL_ENCODED) java client.setContentType(OptimusHTTP.CONTENT_TYPE_JSON);

    Available Types

    • Setup Headers (optional) java ArrayMap<String, String> headerMap = new ArrayMap<>(); headerMap.put("Accept-Encoding", "gzip, deflate"); headerMap.put("Accept-Language", "en-US"); headerMap.put("Content-Language", "en-US"); client.setHeaderMap(headerMap);
  • To make a request create an object of HttpReq class.

    The client.makeRequest() function returns reference to each HttpReq object created which you can save in an ArrayList and then later on call cancel function on them to cancel the requests

    ArrayList<HttpReq> refHttpReqList = new ArrayList<>();
    try {
         // makeRequest() returns the reference of the request made
         // which can be used later to call the cancelReq() if required
         // if no request is made the makeRequest() returns null
        HttpReq req = client.makeRequest(SERVER, params, responseListener);
            if (req != null)
    } catch (Exception e) {
  • To cancel one requests

  • To cancel all requests

    if (refHttpReqList.size() > 0) {
    for (int i = 0; i < refHttpReqList.size(); i++)
  • Implement the Callback

    // Listener for the Response received from server
    private final OptimusHTTP.ResponseListener responseListener = new OptimusHTTP.ResponseListener() {
        public void onSuccess(String msg) {
        public void onFailure(String msg) {



Pull Requests

I welcome and encourage all pull requests. It usually will take me within 24-48 hours to respond to any issue or request. Here are some basic rules to follow to ensure timely addition of your request:

  1. Match coding style (braces, spacing, etc.) This is best achieved using CMD+Option+L (Reformat code) on Mac (not sure for Windows) with Android Studio defaults. This project uses a modified version of Grandcentrix's code style, so please use the same when editing this project.
  2. If its a feature, bugfix, or anything please only change code to what you specify.
  3. Please keep PR titles easy to read and descriptive of changes, this will make them easier to merge :)
  4. Pull requests must be made against develop branch. Any other branch (unless specified by the maintainers) will get rejected.
  5. Check for existing issues first, before filing an issue.
  6. Have fun!
