Add Retrofit2 add ScalarsConverterFactory to your Retrofit.Builder.

adapterBuilder = new Retrofit.Builder()
               .addConverterFactory(ScalarsConverterFactory.create())
               .addConverterFactory(GsonConverterFactory.create());

To use ScalarsCoverter add following dependency to your build graddle

compile 'com.squareup.retrofit2:converter-scalars:2.1.0'
compile 'com.squareup.retrofit2:retrofit:2.1.0' //Adding Retrofit2

For API Call use: ``

Call  *****

Android Code :

.enqueue(new Callback() {
    @Override
    public void onResponse(Call call, Response response) {
        Log.i("Response", response.body().toString());
        //Toast.makeText()
        if (response.isSuccessful()){
            if (response.body() != null){
                Log.i("onSuccess", response.body().toString());
            }else{
                Log.i("onEmptyResponse", "Returned empty response");//Toast.makeText(getContext(),"Nothing returned",Toast.LENGTH_LONG).show();
            }
        }
