// Showing progress dialog
final ProgressDialog progressDialog = new ProgressDialog(HistoryScreenActivity.this, R.style.ProgressBarTansparent);
progressDialog.setIndeterminate(true);
progressDialog.setCancelable(false);
progressDialog.show();
progressDialog.setContentView(R.layout.custom_progressbar_layout);
String url = WebServices.GET_DETAILS_WEB_SERVICE;
JSONObject jsonObjectChield = new JSONObject();
try {
jsonObjectChield.put("PUID", uID);
jsonObjectChield.put("POID", oID);
jsonObjectChield.put("POPF", "html");
} catch (JSONException e) {
e.printStackTrace();
}
String jsonString = jsonObjectChield.toString();
Log.d("Params","" + jsonString);
final JsonObjectRequest postRequest = new JsonObjectRequest(Request.Method.POST, url, jsonObjectChield, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
writeToFile(response.toString());
webViewHistoryDetails.setVisibility(View.VISIBLE);
File file = new File("" + path);
webViewHistoryDetails.loadUrl("file:///" + file + "/report.html");
progressDialog.dismiss();
}
}
// Request a string response from the provided URL.
, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
// Handle your error types accordingly.For Timeout & No connection error, you can show 'retry' button.
// For AuthFailure, you can re login with user credentials.
// In this case you can check how client is forming the api and debug accordingly.
// For ServerError 5xx, you can do retry or handle accordingly.
if (error instanceof NetworkError) {
Toast.makeText(HistoryScreenActivity.this, "No internet connection", Toast.LENGTH_SHORT).show();
} else if (error instanceof ServerError) {
Toast.makeText(HistoryScreenActivity.this, "Our server is busy please try again later", Toast.LENGTH_SHORT).show();
} else if (error instanceof AuthFailureError) {

}
error.printStackTrace();
progressDialog.dismiss();
}
}) {
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json");
// headers.put("Authorization", "Basic c2NvdHQ6dGlnZXI=");
headers.put("token-id", sToken);
String creds = String.format("%s:%s", "scott", "tiger");
String auth = "Basic " + Base64.encodeToString(creds.getBytes(), Base64.DEFAULT);
headers.put("Authorization", auth);
Log.d("SToken",sToken);
// String creds = String.format("%s:%s", "scott", "tiger");
// String auth = "Basic " + Base64.encodeToString(creds.getBytes(), Base64.DEFAULT);

I think your response from your server is in html format.. in order to parse the html response in java there are some ways, But i personally like JSOUP you can also refer links this and this
First in your gradle file add the dependency
compile 'org.jsoup:jsoup:1.8.3' // new version is available i think..
Then parse the html attributes like for example.
Document doc = JSoup.parse(response);
String id = doc.select("input[name=id]").attr("value");
Hope this helps..

This would be a code for Getting response using Volley
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.GET,
url, null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
}
});
// Adding request to request queue
AppController.getInstance().addToRequestQueue(jsonObjReq, tag_json_obj);
For more details: Go through this link
