Convert AsyncTask to RxJava

Bit new to Rx, so am looking for some help on converting the following AsyncTask to Rx, hopefully so I can visualize Rx a bit more with code that I already know that does something. I've found a few other SO answers that were somewhat relevant, but alot of them werent network requests and many used different operators for different answers, so am a bit confused.
Heres the AsyncTask:
Here is my Java code for an WhatsTheWeather App(all code from the MainActivity is included):
public class MainActivity extends AppCompatActivity {
EditText cityName;
TextView resultTextview;
public void findTheWeather(View view){
Log.i("cityName", cityName.getText().toString());
InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
mgr.hideSoftInputFromWindow(cityName.getWindowToken(), 0);
try {
String encodedCityName = URLEncoder.encode(cityName.getText().toString(), "UTF-8");
DownLoadTask task = new DownLoadTask();
task.execute("http://api.openweathermap.org/data/2.5/weather?q=" + cityName.getText().toString() + "&appid=a018fc93d922df2c6ae89882e744e32b");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
Toast.makeText(getApplicationContext(),"Could not find weather",Toast.LENGTH_LONG).show();
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
cityName = (EditText)findViewById(R.id.cityName);
resultTextview = (TextView) findViewById(R.id.resultTextView);
}
public class DownLoadTask extends AsyncTask<String, Void, String> {
#Override
protected String doInBackground(String... urls) {
String result = "";
URL url;
HttpURLConnection urlConnection = null;
try {
url = new URL(urls[0]);
urlConnection = (HttpURLConnection)url.openConnection();
InputStream inputStream = urlConnection.getInputStream();
InputStreamReader reader = new InputStreamReader(inputStream);
int data = reader.read();
while(data != -1){
char current = (char) data;
result +=current;
data = reader.read();
}
return result;
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
try {
String message = "";
JSONObject jsonObject = new JSONObject(result);
String weatherInfo = jsonObject.getString("weather");
Log.i("Weather content", weatherInfo);
JSONArray arr = new JSONArray(weatherInfo);
for(int i=0; i<arr.length(); i++){
JSONObject jsonPart = arr.getJSONObject(i);
String main = "";
String description="";
main = jsonPart.getString("main");
description = jsonPart.getString("description");
if(main != "" && description != ""){
message += main + ": "+ description + "\r\n"; //for a line break
}
}
if (message != ""){
resultTextview.setText(message);
} else {
Toast.makeText(getApplicationContext(),"Could not find weather",Toast.LENGTH_LONG).show();
}
} catch (JSONException e) {
Toast.makeText(getApplicationContext(),"Could not find weather",Toast.LENGTH_LONG).show();
}
}
}

Try this.
public void networkCall(final String urls) {
Observable.fromCallable(new Func0<String>() {
#Override
public String call() {
String result = "";
URL url = null;
HttpURLConnection urlConnection = null;
try {
url = new URL(urls);
urlConnection = (HttpURLConnection) url.openConnection();
InputStream inputStream = urlConnection.getInputStream();
InputStreamReader reader = new InputStreamReader(inputStream);
int data = reader.read();
while (data != -1) {
char current = (char) data;
result += current;
data = reader.read();
}
try {
String message = "";
JSONObject jsonObject = new JSONObject(result);
String weatherInfo = jsonObject.getString("weather");
Log.i("Weather content", weatherInfo);
JSONArray arr = new JSONArray(weatherInfo);
for (int i = 0; i < arr.length(); i++) {
JSONObject jsonPart = arr.getJSONObject(i);
String main = "";
String description = "";
main = jsonPart.getString("main");
description = jsonPart.getString("description");
if (main != "" && description != "") {
message += main + ": " + description + "\r\n"; //for a line break
}
}
return message;
} catch (JSONException e) {
Toast.makeText(getApplicationContext(), "Could not find weather", Toast.LENGTH_LONG).show();
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
})
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Subscriber<String>() {
#Override
public void onCompleted() {
}
#Override
public void onError(Throwable e) {
}
#Override
public void onNext(String message) {
if (message != ""){
resultTextview.setText(message);
} else {
Toast.makeText(getApplicationContext(),"Could not find weather",Toast.LENGTH_LONG).show();
}
}
});
}
But, i would recommend to use Retrofit and RxJava together.

There are couple of things you should know before integrating Retrofit.
Try not to use the older version of Retrofit
Retrofit2 is the one which you are supposed to use at current
Try avoiding code integration of Retrofit with RxJava or RxAndroid
at current(Too much complexity for beginner)
Make sure you are familiar with GSON or Jackson too.
HttpClient is depreciated while OkHttp is comparatively faster than HttpUrlConnection which is generally used by Retrofit2
Finally, here the link for the Retrofit2. It is well detailed and easy to understand. Jack Wharton has tried his best to make it simple to understand as possible.

JAVA file
private void getWeatherData(String cityName) throws JSONException {
HttpURLConnection conn = null;
StringBuilder jsonResults = new StringBuilder();
try {
StringBuilder sb = new StringBuilder(WEATHER_API_BASE + API_KEY + TYPE + cityName +OUT_JSON);
Log.e(TAG , sb.toString());
URL url = new URL(sb.toString());
conn = (HttpURLConnection) url.openConnection();
InputStreamReader in = new InputStreamReader(conn.getInputStream());
// Load the results into a StringBuilder
int read;
char[] buff = new char[1024];
while ((read = in.read(buff)) != -1) {
jsonResults.append(buff, 0, read);
}
} catch (MalformedURLException e) {
Log.e(TAG, "Error processing Weather API URL", e);
} catch (IOException e) {
Log.e(TAG, "Error connecting to Weather API", e);
} finally {
if (conn != null) {
conn.disconnect();
}
}
try {
Log.e(TAG, "in try2");
// Create a JSON object hierarchy from the results
JSONObject jsonObj = new JSONObject(jsonResults.toString());
JSONArray forecastJsonArray = jsonObj.getJSONArray("hourly_forecast");
Log.e(TAG , "Length:" + String.valueOf( forecastJsonArray.length() ));
} catch (Exception e) {
Log.e(TAG, "Cannot process JSON results", e);
}
}
The above code works for other api from which I retrive JSON but not able to figure out why is it not working for this.
JSON
http://api.wunderground.com/api/73d7d46dcd6153a7/hourly/q/Chandigarh.json

How you consume the api? Are you using AsyncTask? You cannot simply make an api call by calling the method. Network operation need to be run asynchronously. I have tried runnning your code in AsyncTask, and it does working.
private class WeatherDataTask extends AsyncTask<String, String, String> {
public WeatherDataTask() {
}
#Override
protected String doInBackground(String... params) {
HttpURLConnection conn = null;
StringBuilder jsonResults = new StringBuilder();
try {
StringBuilder sb = new StringBuilder(params[0]);
URL url = new URL(sb.toString());
conn = (HttpURLConnection) url.openConnection();
InputStreamReader in = new InputStreamReader(conn.getInputStream());
// Load the results into a StringBuilder
int read;
char[] buff = new char[1024];
while ((read = in.read(buff)) != -1) {
jsonResults.append(buff, 0, read);
}
} catch (MalformedURLException e) {
Log.e("WeatherTask", "Error processing Weather API URL", e);
} catch (IOException e) {
Log.e("WeatherTask", "Error connecting to Weather API", e);
} finally {
if (conn != null) {
conn.disconnect();
}
}
return jsonResults.toString();
}
#Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
if(null != s){
try {
JSONObject jsonObj = new JSONObject(s);
JSONArray forecastJsonArray = jsonObj.getJSONArray("hourly_forecast");
Log.i("ForeCastJason", forecastJsonArray.toString());
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}
Call this method class
new WeatherDataTask().execute("http://api.wunderground.com/api/73d7d46dcd6153a7/hourly/q/Chandigarh.json");

I solved it using Async Http Client

HttpUrlConnection does not work on mobile device but on emulator

all of a sudden my mobile device can't connect to the local server anymore. async tasks are not executed and i just can't figure out why. slowly i'm getting really desperate because in my opinion i didn't change anything to cause this.

HttpClient is not supported any more in sdk 23. You have to use URLConnection or downgrade to sdk 22 (compile 'com.android.support:appcompat-v7:22.2.0')
If you need sdk 23, add this to your gradle:
android {
useLibrary 'org.apache.http.legacy'
}
HttpClient won't import in Android Studio

You should think about using a HTTP library, there is a bunch of them on internet, some are really easy to use, optimize and errorless.
For example, Volley (made by Google, I really like this one), okHttp or Picasso (for image).
You should take a look at this.

If you want to send (output), for example with POST or PUT requests you need to use this :-
urlConnection.setDoOutput(true);
In your code :-
public class Login extends AsyncTask<String, Void, String>{
private String loginUrl = "http://...";
private int loginSuccess = 0;
public String getToken(String fromJson) throws JSONException {
JSONObject json = new JSONObject(fromJson);
if(json.has("api_authtoken")) {
loginSuccess = 1;
String appToken = json.getString("api_authtoken");
return appToken;
}
else {
return json.toString();
}
}
public String doInBackground(String... arg0) {
// so that they can be closed in the finally block.
HttpURLConnection urlConnection = null;
BufferedReader reader = null;
String authToken;
try {
// get logged in to get the api_authtoken
String email = (String) arg0[0];

// Create the request and open the connection
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestMethod("POST");
urlConnection.setRequestProperty("Content-Type", "application/json");
urlConnection.setRequestProperty("Accept", "application/json");
urlConnection.setDoOutput(true); // HERE
//put values of edittexts into json-Object
JSONObject data = new JSONObject();
try {
data.put("email", email);
data.put("password", password);
} catch(JSONException e) {
Log.e("EXCEPTION", "unexpected JSON exception", e);

how to create a string representation of json

hey there guys and girls i have this code that saves json as a string representation, i still haveing a little trouble understanding how the entity section works, and need to know how to change my code so that it works, this is the error im getting,
Error saving string java.lang.NumberFormatException: unable to parse '[{"story_name":"Story One"},{"story_name":"Story Two"},{"story_name":"Story Three"},{"story_name":"Story Four"},{"story_name":"Story Five"},{"story_name":"Story Six"}]' as integer
i was getting help from someone last night that almost got me there but still need a little more understanding of how it works and wht i get the parse error here is my full code

My guess it your code failed at this lines:
responseInteger = Integer.valueOf(entityString);
After a little inspection, I see that your JSON is:
[{"story_name":"Story One"},{"story_name":"Story Two"},{"story_name":"Story Three"},{"story_name":"Story Four"},{"story_name":"Story Five"},{"story_name":"Story Six"}]
A closer inspection using JSON Viewer, I see that your structure is like this:
The problem is
I don't see any integer in this JSON. You might have to use a combination of JSONObject and JSONArray to parse your it properly.

Your problem is this line
responseInteger = Integer.valueOf(entityString);
entityString is
'[{"story_name":"Story One"},{"story_name":"Story Two"},{"story_name":"Story Three"},{"story_name":"Story Four"},{"story_name":"Story Five"},{"story_name":"Story Six"}]'
And when Integer.valueOf tries to parse it, it can't parse it as an integer, so it throws a NumberFormatException.

Sample JSon string:
{
Stories:
[
{
"story_name": "Story One"
},
{
"story_name": "Story Two"
}
]
}
Create a Class:
public class Story
{
public String stort_name;
}
class CollectionOfStories
{
public List<Story> Stories;
public CollectionOfSections()
{
Stories= new ArrayList<Story>();
}
}
Finally:
private CollectionOfStories convertDataFromJSonToObject(String jsonString)
{
JSONObject jso;
CollectionOfStories colStories = new CollectionOfStories();
try
{
jso = new JSONObject(jsonString);
JSONArray ja = jso.getJSONArray("Stories");
for (int i = 0; i < ja.length(); i++)
{
Story s = new Story();
JSONObject jsonSection = ja.getJSONObject(i);
s.stort_name = jsonSection.getString("story_name");
//add it to sections list
colStories.Stories.add(s);
}
}
catch (NumberFormatException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (JSONException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
return colStories;
}
