This my ActivityRegister.java class:

This is the stringResponse I'm giving:
public void callServiceWithURLPart(final Activity activity, final String urlPart, final String postBody, final ICallServiceResult callServiceResult){
final ProgressDialog progress = new ProgressDialog(activity);
progress.setTitle("Processing..");
progress.setProgressStyle(android.R.attr.progressBarStyleSmall);
//progress.setMessage("Connecting...");
progress.show();
ConnectivityManager connMgr = (ConnectivityManager)
activity.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connMgr.getActiveNetworkInfo();
if (networkInfo != null && networkInfo.isConnected()) {
Runnable r = new Runnable() {
@Override
public void run() {
OkHttpClient client = new OkHttpClient.Builder().connectTimeout(60, TimeUnit.SECONDS).build();
try{
String servicePath = kURLBase + urlPart;
Log.d("OkHttpClient","servicePath = "+servicePath);
Log.d("postBody",postBody);
Request request = new Request.Builder()
.url(servicePath)
.put(RequestBody.create(MEDIA_TYPE_JSON, postBody))
.build();
final Response response = client.newCall(request).execute();
if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
//final String stringResponse = response.body().string();
final String stringResponse = "{'serviceName': 'registerToken', 'emailID': '', 'token': ''}";
if(stringResponse!=null){
Log.d("ServiceResponseString",stringResponse);
}else {
Log.d("ServiceResponseString","null");
}
if(callServiceResult!=null){
activity.runOnUiThread(new Runnable() {
@Override
public void run() {
progress.dismiss();
if(stringResponse!=null){
callServiceResult.serviceResult(urlPart,true,stringResponse);
}
else {
callServiceResult.serviceResult(urlPart,false,stringResponse);
}
}
});
}
} catch (Exception e){
Log.d("OkHttpClient exception",e.toString());
final Exception _e = e;
if(callServiceResult!=null){
activity.runOnUiThread(new Runnable() {
@Override
public void run() {
progress.dismiss();
callServiceResult.serviceResult(urlPart,false,_e.toString());
}
});
}
}
}
};
Thread t = new Thread(r);
t.start();
} else {
progress.dismiss();
fastToast(activity,"Connect to internet and try again.");
}
}
My base URL is: public static final String kURLBase = "https://api-test.allianz.com/digithonempwebservice/rest"; which is being provided when stringResponse is asked. Any help would be appreciated.

Try this:
String retCode = jsonObject.optString("retCode");
The difference is that
optStringreturns the empty string ("") if the key you specify doesn't exist.getStringon the other hand throws aJSONException. UsegetStringif it's an error for the data to be missing, or optString if you're not sure if it will be there.

As the crash logs suggest, you are trying to access retCode from the json but it not there.
You should use optString rather than getString , if you are not sure about the fields.
