Get Response as String from your Retrofit Call

In This blog, we will learn about how to Get Response as String from your Retrofit Call.

Many times, during app development we need to use third-party modules and their response is not in our hand. I faced the same issue the response sent from third-party module was a simple string (no formatting done for any parser to work).

Being familiar with retrofit and its custom Converters for the response I got stuck with the response from this API. The response was in front of me through logs but was not accessible as retrofit was rejecting to detect it. So, I had to change the request a bit but implementing it was very easy.

APPROACH

Your Call Should Expect the Default ResponseBody Object in response.
When the response is received you need to call response.body().string() method to get the response as a plain string.

CODE

Retrofit call Object :

    @FormUrlEncoded
    @POST
    Call<ResponseBody> getStringResponse(
            @Url String url
            // add Fields required as per your use
    );

@FormUrlEncoded

@POST

Call<ResponseBody> getStringResponse(

@Url String url

// add Fields required as per your use

);

Retrofit Callback Object :

 private Callback<ResponseBody> ResponseCallBack =  new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
            try {

                String responseRecieved = response.body().string();
            // Add Your Logic

            }catch (Exception e){
                e.printStackTrace();
            }
        }
        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {
            t.printStackTrace();

        }
    };

private Callback<ResponseBody> ResponseCallBack = new Callback<ResponseBody>() {

@Override

public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {

try {

String responseRecieved = response.body().string();

// Add Your Logic

}catch (Exception e){

e.printStackTrace();

}

@Override

public void onFailure(Call<ResponseBody> call, Throwable t) {

t.printStackTrace();

}

};

And That’s It.

Keep coding and Keep Sharing 🙂
