Name Your Library as httpConnectionlib and click finish.

 Your module httpConnection has been added.  Now we need to add code to our library. Create a new Class in the module and name that class. Add the required file to the library.

I have added two classes, FetchData and PutData.

So now, our library is finished, it’s time to publish it.

JitPack will be used to publish the library because it makes the procedure a great deal simpler. 

A GitHub repository is all you require.

Publishing the Android Library

Now we are going to create a new GitHub  public repository and push our code:

Now you can set up your Android Studio to push the code to this repository. You can do it as per my previous blog:  

How to Use Git in Android Studio

Now in your GitHub repository, you should be able to see your code:

Now you need to click on the release button to release this code for usage

Publish the release. Open a new tab and go to jitpack.io.
Insert your repository address and click on Lookup. Your releases will be listed. Now click on Get it.

click on the get it button there and you will get the instructions on how to use it:

Now your Android Library has been published and is ready to be used.

Using the Android Library

Now you can use this android library in any of your projects.
In your project’s build. Gradle add the following line
maven { url ‘https://jitpack.io’ }

And you can add a dependency library here

implementation 'com.GitHub.karjol:httpconnection:0.1.0'

private void getSubjectList(String featureSelected, String semSelected) {
    if(!featureSelected.equals("") && !semSelected.equals("")) {
        progressBar.setVisibility(View.VISIBLE);
        Handler handler1 = new Handler();
        handler1.post(new Runnable() {
            @Override
            public void run() {
                String[] field = new String[2];
                field[0] = "feature";
                field[1] = "sem";
                String[] data = new String[2];
                data[0] = featureSelected;
                data[1] = semSelected;
PutData putData = new PutData("https://grcamp.in/qbank/subject.php", "POST", field, data);
                if (putData.startPut()) {
                    if (putData.onComplete()) {
                       progressBar.setVisibility(View.GONE);
                       String result = putData.getResult();
                       if(result.equals("All fields are required")){
         Toast.makeText(getApplicationContext(),result,Toast.LENGTH_SHORT).show();

                        }
                        else {
                              try {
                                JSONArray jsonarry = new JSONArray(result);
                                //JSONArray subjects = jsonObj.getJSONArray("subname");
                                for (int i = 0; i < jsonarry.length(); i++) {
                                    JSONObject jsonobject = jsonarry.getJSONObject(i);
                                    list.add(jsonobject.getString("subname"));
                                }

                            } catch (JSONException e) {
                                e.printStackTrace();
                            }

                            }

                        }
                    }
                }
            });
    }
    else {
Toast.makeText(getApplicationContext(),"All fields required", Toast.LENGTH_SHORT).show();
    }
}

Example for fetch Data:

buttonFetch.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
        progressBar.setVisibility(View.VISIBLE);
        //Starting Read data from URL
        Handler handler = new Handler();
        handler.post(new Runnable() {
@Override
public void run() {
        FetchData fetchData = new FetchData("https://grcamp.in/qbank/Fetchstudents.php");
        if (fetchData.startFetch()) {
        if (fetchData.onComplete()) {
        String result = fetchData.getResult();
        progressBar.setVisibility(View.GONE);
        textView.setText(result);
        Log.i("FetchData", result);
        }
        }
        }
        });
        //End Read data from URL
        }
        });
