Connect Android App to Github API

Question

I\'ve been checking around for some time, but still can\'t find information on this how exactly to connect my android app to the Github API. I had it registered, had a token

Answer 1

I've used below code to connect to GitHub Search Repo API in my android app.

---

//Method 1: To Authorize API access for all HTTP call
            //Uncomment this part of code and input your username and password
//            Authenticator.setDefault(new Authenticator() {
//                @Override
//                protected PasswordAuthentication getPasswordAuthentication() {
//                    return new PasswordAuthentication("username", "password".toCharArray());
//                }
//            });
            HttpURLConnection urlConnection;
            URL url;
            InputStream inputStream;

            try{
                url = new URL("https://api.github.com/search/repositories?q="+"searchText");
                urlConnection = (HttpURLConnection) url.openConnection();

//Method 2: To Authorize API access while making HTTP request

                //Uncomment this part of code and input your username and password
//                String basicAuth = "Basic "+Base64.encodeToString("username:password".getBytes(), Base64.NO_WRAP);
//                urlConnection.setRequestProperty ("Authorization", basicAuth);

                //set request type
                urlConnection.setRequestMethod("GET");

                //if you uncomment the following line GitHub API will not respond
//                urlConnection.setDoOutput(true);

                urlConnection.setDoInput(true);
                urlConnection.connect();
                //check for HTTP response
                int httpStatus = urlConnection.getResponseCode();

                //if HTTP response is 200 i.e. HTTP_OK read inputstream else read errorstream
                if (httpStatus != HttpURLConnection.HTTP_OK) {
                    inputStream = urlConnection.getErrorStream();
                //print GitHub api hearder data
                    Map<String, List<String>> map = urlConnection.getHeaderFields();
                    System.out.println("Printing Response Header...\n");
                    for (Map.Entry<String, List<String>> entry : map.entrySet()) {
                        System.out.println(entry.getKey()
                                + " : " + entry.getValue());
                    }
                }
                else {
                    inputStream = urlConnection.getInputStream();
                }

                //read inputstream
                BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
                String temp,response="";
                while((temp = bufferedReader.readLine())!=null){
                    response+=temp;
                }

                //GitHub api has limit to access over http. 
                //Api rate limit is 10req/min for unauthenticated user and 30req/min is for authenticated user
                boolean apiLimitExceeded = "false";
                if(response.contains("API rate limit exceeded")){
                    apiLimitExceeded =true;
                }else {
                    //convert data string into JSONObject
                    JSONObject obj = (JSONObject) new JSONTokener(response).nextValue();
                    JSONArray items = obj.getJSONArray("items");

                    //total result count and result status
                    total_count = obj.getString("total_count");
                    incomplete_results = obj.getString("incomplete_results");
                }

                urlConnection.disconnect();
            } catch (MalformedURLException | ProtocolException | JSONException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
