Convert an inputstream to a string value in Java Android App

Question

I'm having trouble with function(s) I'm writing. I'm trying to convert an inputstream to a string value. I've written two functions and I'm attempting to extract the String value but my Log.e response is returning NULL. Below is my syntax. What am I doing wrong? Thanks

If you can't view my below syntax, please visit http://pastebin.com/5rr6pK6G

    public JSONArray GetCityDetails(String StateID) {

    @SuppressWarnings("deprecation")
    String url = "http://mywebsite.com/getCity.php?StateID="+URLEncoder.encode(StateID);

    HttpEntity httpEntity = null;

    try{

         DefaultHttpClient httpClient = new DefaultHttpClient();
         HttpGet httpGet = new HttpGet(url);

         HttpResponse httpResponse = httpClient.execute(httpGet);

         httpEntity = httpResponse.getEntity();


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

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


    JSONArray jsonArray = null;
    if(httpEntity !=null){
        try{

            InputStream entityResponse = httpEntity.getContent();
            // not working
            String entityResponseAfterFunctionCall2 = readFully(entityResponse);
            // not working
            String entityResponseAfterFunctionCall3 = letsDoThisAgain(entityResponse);
            Log.e("Entity Response: ", entityResponseAfterFunctionCall3);

            jsonArray = new JSONArray(entityResponseAfterFunctionCall3);

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

    return jsonArray;
    }

    public String readFully(InputStream entityResponse) throws IOException {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    byte[] buffer = new byte[1024];
    int length = 0;
    while ((length = entityResponse.read(buffer)) != -1) {
        baos.write(buffer, 0, length);
    }
    return baos.toString();
    }

    public String letsDoThisAgain(InputStream entityResponse){

    InputStreamReader is = new InputStreamReader(entityResponse);
    StringBuilder sb = new StringBuilder();
    BufferedReader br = new BufferedReader(is);
     try {
        String read = br.readLine();

        while(read !=null){
            sb.append(read);
            read = br.readLine();
        }

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

        return sb.toString();   
     }

    }

Do you have access to EntityUtils ? Check out its methods.

The other thing where you are checking httpEntity != null, should probably be looking at:

httpEntity.getContentLength();

This is in case you aren't getting anything back, it should be greater than 0. Your method letsTryThatAgain looks correct. I found this Stack Overflow answer that looks like you are doing the right thing, maybe the content length is 0.
