JSON parsing android

JSON parsing android - java

I need advice about my code.
I'm trying to parse a JSON array generated by the PHP function json_encode().
My json:
{"data": [{"streamer":"froggen","yt_length":"25078"},{"streamer":"wingsofdeath","yt_length":"8979"},{"streamer":"guardsmanbob","yt_length":"4790"},{"streamer":"kaostv","yt_length":"4626"},{"streamer":"kungentv","yt_length":"3883"},{"streamer":"destiny","yt_length":"3715"},{"streamer":"zekent","yt_length":"3428"},{"streamer":"athenelive","yt_length":"1673"},{"streamer":"frommaplestreet","yt_length":"1614"},{"streamer":"keyorikeys","yt_length":"1410"},{"streamer":"riotgamesturkish","yt_length":"1397"},{"streamer":"vman7","yt_length":"1022"},{"streamer":"tiensinoakuma","yt_length":"967"},{"streamer":"affenklappe","yt_length":"748"},{"streamer":"teamkeyd","yt_length":"747"},{"streamer":"lagtvmaximusblack","yt_length":"683"},{"streamer":"lolgameru","yt_length":"665"},{"streamer":"gruntartv","yt_length":"585"},{"streamer":"entenzwerg","yt_length":"579"},{"streamer":"lolgameru_cauthonpro","yt_length":"506"},{"streamer":"basickz","yt_length":"488"},{"streamer":"ilysuiteheart","yt_length":"491"},{"streamer":"kireiautumn","yt_length":"485"},{"streamer":"ultimavv","yt_length":"471"}]}
Java class:
public class JSONParser {
static InputStream is = null;
static JSONObject jObj = null;
static String json = "";
String response = "";
// constructor
public JSONParser() {
}
public JSONObject getJSONFromUrl(String url) {
// Making HTTP request
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpPost = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}
// return JSON String
return jObj;
}
}
And my activity:
public class AndroidJSONParsingActivity extends ListActivity {
// url to make request
private static String url = "http://ololo.tv/vasa";
// JSON Node names
private static final String TAG_DATA = "data";
private static final String TAG_STREAMER = "streamer";
private static final String TAG_VIEWERS = "yt_length";
// contacts JSONArray
JSONArray data = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Hashmap for ListView
ArrayList<HashMap<String, String>> dataList = new ArrayList<HashMap<String, String>>();
// Creating JSON Parser instance
JSONParser Parser = new JSONParser();
// getting JSON string from URL
JSONObject json = null;
json = Parser.getJSONFromUrl(url);
try {
// Getting Array of Contacts
data = json.getJSONArray(TAG_DATA);
// looping through All Contacts
for(int i = 0; i < data.length(); i++){
JSONObject c = data.getJSONObject(i);
// Storing each json item in variable
String streamer = c.getString(TAG_STREAMER);
String viewers = c.getString(TAG_VIEWERS);
//String link = c.getString();
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_STREAMER, streamer);
map.put(TAG_VIEWERS, viewers);
//map.put(TAG_URL, link);
// adding HashList to ArrayList
dataList.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
/**
* Updating parsed JSON data into ListView
* */
ListAdapter adapter = new SimpleAdapter(this, dataList,
R.layout.list_item,
new String[] { TAG_STREAMER, TAG_VIEWERS /*TAG_URL*/ }, new int[] {
R.id.streamer, R.id.viewers /*R.id.url*/ });
setListAdapter(adapter);
// selecting single ListView item
ListView lv = getListView();
// Launching new screen on Selecting Single ListItem
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting values from selected ListItem
String name = ((TextView) view.findViewById(R.id.streamer)).getText().toString();
String viewers_count = ((TextView) view.findViewById(R.id.viewers)).getText().toString();
//String url = ((TextView) view.findViewById(R.id.url)).getText().toString();
// Starting new intent
Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class);
in.putExtra(TAG_STREAMER, name);
in.putExtra(TAG_VIEWERS, viewers_count);
//in.putExtra(TAG_PHONE_MOBILE, url);
startActivity(in);
}
});
}
}
I tried using breakpoints, and see that when I put a breakpoint after GetEntity, the program doesn't get there because it crashed early, or something.
This my async task.
public class ParsingTask extends AsyncTask<String, Void, Void>{
JSONParser Parser = new JSONParser();
protected Void doInBackground(String... urls) {
ArrayList<HashMap<String, String>> dataList = new ArrayList<HashMap<String, String>>();
JSONObject json = Parser.getJSONFromUrl(url);
try {
// Getting Array of Contacts
data = json.getJSONArray(TAG_DATA);
// looping through All Contacts
for(int i = 0; i < data.length(); i++){
JSONObject c = data.getJSONObject(i);
// Storing each json item in variable
String streamer = c.getString(TAG_STREAMER);
String viewers = c.getString(TAG_VIEWERS);
//String link = c.getString();
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_STREAMER, streamer);
map.put(TAG_VIEWERS, viewers);
//map.put(TAG_URL, link);
// adding HashList to ArrayList
dataList.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
/**
* Updating parsed JSON data into ListView
* */
ListAdapter adapter = new SimpleAdapter(this, dataList,
R.layout.list_item,
new String[] { TAG_STREAMER, TAG_VIEWERS /*TAG_URL*/ }, new int[] {
R.id.streamer, R.id.viewers /*R.id.url*/ });
setListAdapter(adapter);
return null;
}
protected void onProgressUpdate() {
}
protected void onPostExecute() {
}
}
ListAdapter error, seems like something wrong in "this". This my version how cut off code, where it stop return variables. Sorry for bad english, but i hope you understand me :)
Add my php json maker. Mb problem there?!
<?php
mysql_connect("localhost","root","");
if (!mysql_select_db("ololo")) {
echo "Unable to select ololo: " . mysql_error();
}
$sql=mysql_query("select streamer, yt_length from pm_videos where category='1'");
if(!$sql) exit("Error - ".mysql_error().", ".$tmp_q);
while($row=mysql_fetch_assoc($sql)){
$output[]=$row;
}
$json = json_encode($output);
header('Content-Type: application/json');
print "{\"data\": ${json}}";
mysql_close();
?>

You programm crashes because you are running
json = Parser.getJSONFromUrl(url);
in the UI Thread context. You have to use an AsyncTask
Code looks good. The only problem is that
public class ParsingTask extends AsyncTask<String, Void, ArrayList<HashMap<String, String>>>{
JSONParser Parser = new JSONParser();
protected Void doInBackground(String... urls) {
ArrayList<HashMap<String, String>> dataList = new ArrayList<HashMap<String, String>>();
JSONObject json = Parser.getJSONFromUrl(url);
try {
// Getting Array of Contacts
data = json.getJSONArray(TAG_DATA);
// looping through All Contacts
for(int i = 0; i < data.length(); i++){
JSONObject c = data.getJSONObject(i);
// Storing each json item in variable
String streamer = c.getString(TAG_STREAMER);
String viewers = c.getString(TAG_VIEWERS);
//String link = c.getString();
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_STREAMER, streamer);
map.put(TAG_VIEWERS, viewers);
//map.put(TAG_URL, link);
// adding HashList to ArrayList
dataList.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
/**
* Updating parsed JSON data into ListView
* */
return dataList;
}
protected void onPostExecute(ArrayList<HashMap<String, String>> dataList) {
ListAdapter adapter = new SimpleAdapter(AndroidJSONParsingActivity.this, dataList,
R.layout.list_item,
new String[] { TAG_STREAMER, TAG_VIEWERS /*TAG_URL*/ }, new int[] {
R.id.streamer, R.id.viewers /*R.id.url*/ });
setListAdapter(adapter);
}

Have you heard about gson (docs)?
public static final class Content {
#SerializedName("streamer") // you don't need to specify this, JFYI
String streamer;
#SerializedName("yt_length") // you don't need to specify this, JFYI
String yt_length;
}
public static final class Data {
#SerializedName("data")
List<Content> data;
}
public static void main (String[] args) {
Gson gson = new GsonBuilder().create();
Data data = gson.fromJson(jsonString, Data.class);
}
And remember, you cannot call network operations on UI thread! this is reason of what you have for now.

In your SessionManager you're not saving your List into SharedPrefs. You should do something like this:
public static final String MY_LIST = "my_list";
private static final Type LIST_TYPE = new TypeToken<List<BetDisplayer>>() {}.getType();
to save:
public void setListwriter(ArrayList<BetDisplayer> listwriter) {
this.listwriter = new ArrayList<BetDisplayer>(listwriter);
mPrefs.edit()
.putString(MY_LIST, new Gson().toJson(listwriter));
.commit();
}
to load:
public ArrayList<BetDisplayer> getListwriter() {
if (listwriter == null) {
listwriter = new Gson().fromJson(mPrefs.getString(MY_LIST, null), LIST_TYPE);
if(listwriter == null){
listwriter = new ArrayList<BetDisplayer>();
}
}
return listwriter;
}
Your BetDisplayer must implements Serializable.
See here: Android array to Sharedpreferences with Gson
To use Gson just add this dependency: 'com.google.code.gson:gson:2.3.1' or download the .jar
UPDATE:
Create a Singleton that holds one reference only to your SharedPreferences editor, it's just a will guess but I think you are using different context to get your editor and that could be the problem (UPDATE 2: it's not, check here, but the Singleton approach it's a plus):
private static SharedPreferences mPrefs;
private static SessionManager sInstance = null;
protected SessionManager() {
mPrefs = AppController.getInstance().getApplicationContext().getSharedPreferences(PREF_NAME, Context.MODE_PRIVATE);
}
public static SessionManager getInstance() {
if (sInstance == null) {
sInstance = new SessionManager();
}
return sInstance;
}
And when you need to use SharedPreferences use SessionManager().getInstance().someMethod();

ProgressDialog not showing up in onPreExecute()

I saw that .get() is the problem, but I try without him and nothing. If possible help me. The ProgressDialog execute after doInBackground() and after run onPostExecute "dismiss" and then ProgressDialog not show.
public List<Usuario> getListaUsuario(Activity activity) {

}

The problem is
new WebServiceCliente(activity).execute(aux).get();
get() is a blocking call, and with the UI Thread blocked waiting for get() to return there is no one that can take care of drawing the ProgressDialog. Remove get(), and use a Delegate to return the results on your AsyncTask to the UI Thread, Here there is an example
Edit:
your interface should be like:
public interface CallbackReciever { public void receiveData(String[] result); }
the constructor of your AsynTask changes like
CallbackReciever mListener;
public WebServiceCliente(Activity ac, CallbackReciever listener) {
activity = ac;
mListener = listener;
}
in onPostExecute:
#Override
protected void onPostExecute(String[] params) {
try {
if (mListener != null) {
mListener.receiveData(params);
}
// stop Dialog
if (pDialog.isShowing()) {
pDialog.dismiss();
}
} catch (Exception e) {
e.printStackTrace();
}
}
In receiveData, in your Activity, you have to process String[] result

$post["email"] = $row["email"];
$post["address"] = $row["address"];
$post["remarks"] = $row["remarks"];
//update json response
array_push($response["post"], $post);
}
echo json_encode($response);
}
else{
$response["success"] = 0;
$response["message"] = "No available patient information";
die(json_encode($response));
}
?>

You should change this part Apatient = new JSONArray(json);
Create a JSONObject JSONObject ApatientObject = new JSONObject(json);
Then get your JSONArray from there like this :
Apatient = new JSONArray(ApatientObject.getJSONArray("post"))
The problem is that the response you receive from the server is a JSONObject, not a JSONArray. The JSONObject contains 2 Strings, "message" and "success", and also contains a JSONArray "post" which holds the data you are looking for.
EDIT:
If you're only retreiving data from the server then it can be useful to think in terms of using GET for retrieving / viewing information and POST for creating / editing information as mentioned here:
When do you use POST and when do you use GET?

Trouble with JSON return in Android

I am having an issue with what my JSON returns in the toast. The toast is there to let me know that the query was successful. The problem is that the toast is triggered, meaning that the query was successful, but it does not contain anything more than Success []. A successful query is supposed to come back as Success [JSON RESULTS HERE].

your string comparison is incorrect. Instead of
result=="SUCCESS"
use
"SUCCESS".equals(result)
(or better even, return a boolean)

Besides the comparison issue (identified by #njzk2) I think you are forgetting to print the size of your list.
Change:
Toast.makeText(MainActivity.this, "Success "+deptList, Toast.LENGTH_LONG).show();
To this:
Toast.makeText(MainActivity.this, "Success "+deptList.size(), Toast.LENGTH_LONG).show();

Maybe you used == to test String equality, and "SUCCESS" shared the same constant String, so you always get the fake True result. Try result.equals("SUCCESS") and run again.

Try as follows:-
try {
JSONObject jObject = new JSONObject(jsonString);
JSONObject jLeagues = jObject.getJSONObject("leagues");
JSONArray jLeague = jLeagues.getJSONArray("league");
deptList = new ArrayList<DEPT_HOLD>();
for (int i = 0; i < jLeague.length(); i++) {
JSONObject jl = jLeague.getJSONObject(i);
deptList.add(new DEPT_HOLD(jl.getString("name")));
deptList.add(new DEPT_HOLD(jl.getString("id")));
deptList.add(new DEPT_HOLD(jl.getString("homeURL")));
}
StringBuilder totalDept = new StringBuilder();
for (int i = 0; i < deptList.size(); i++) {
DEPT_HOLD dept = deptList.get(i);
String value = dept.getName();
totalDept.append(value + ", \n");
}
Toast.makeText(ExampleJSONActivity.this, "success " + totalDept,
Toast.LENGTH_LONG).show();
} catch (Exception e) {
// TODO: handle exception
}
DEPT_HOLD:-
public class DEPT_HOLD {
private String name;
public DEPT_HOLD(String name) {
super();
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
