Twitter's live streaming API unauthorized(android)

I found this old android example code that can filter tweets from Twitter's live streaming API according to the input of user, but the problem is that it uses the basic authorization.
Obviously it wouldn't work and I got the "401 unauthorized" error.
Here is the original code:
package com.teleknesis.android.twitter.livestream;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URI;
import java.util.ArrayList;
import java.util.HashMap;

public class TwitterLiveStreamingActivity extends Activity {
private List<HashMap<String,String>> mTweets = new ArrayList<HashMap<String,String>>();
private SimpleAdapter mAdapter;
private boolean mKeepRunning = false;
private String mSearchTerm = "";
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mAdapter = new SimpleAdapter(this, mTweets, android.R.layout.simple_list_item_2, new String[] {"Tweet", "From"}, new int[] {android.R.id.text1, android.R.id.text2});
((ListView)findViewById(R.id.Tweets)).setAdapter(mAdapter);
}
public void startStop( View v ) {
if( ((Button)v).getText().equals("Start") ) {
mSearchTerm = ((EditText)findViewById(R.id.SearchText)).getText().toString();
if( mSearchTerm.length() > 0 ) {
new StreamTask().execute();
mKeepRunning = true;
((Button)v).setText("Stop");
}
else {
Toast.makeText(this, "You must fill in a search term", Toast.LENGTH_SHORT).show();
}
}
else {
mKeepRunning = false;
((Button)v).setText("Start");
}
}
private class StreamTask extends AsyncTask<Integer, Integer, Integer> {
private String mUrl = "https://stream.twitter.com/1/statuses/filter.json?track=";
#Override
protected Integer doInBackground(Integer... params) {
try {
DefaultHttpClient client = new DefaultHttpClient();
Credentials creds = new UsernamePasswordCredentials("username", "password");
client.getCredentialsProvider().setCredentials( new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT), creds);
HttpGet request = new HttpGet();
request.setURI(new URI("https://stream.twitter.com/1/statuses/filter.json?track=" + mSearchTerm));
HttpResponse response = client.execute(request);
InputStream in = response.getEntity().getContent();
BufferedReader reader = new BufferedReader( new InputStreamReader(in) );
parseTweets(reader);
in.close();
}
catch (Exception e) {
Log.e("Twitter", "doInBackground_" + e.toString());
}
return new Integer(1);
}
private void parseTweets( BufferedReader reader ) {
try {
String line = "";
do {
line = reader.readLine();
Log.d("Twitter", "Keep Running: " + mKeepRunning
+ " Line: " + line);
JSONObject tweet = new JSONObject(line);
HashMap<String, String> tweetMap = new HashMap<String, String>();
if (tweet.has("text")) {
tweetMap.put("Tweet", tweet.getString("text"));
tweetMap.put("From", tweet.getJSONObject("user")
.getString("screen_name"));
mTweets.add(0, tweetMap);
if (mTweets.size() > 10) {
mTweets.remove(mTweets.size() - 1);
}
//mAdapter.notifyDataSetChanged();
publishProgress(1);
}
} while (mKeepRunning && line.length() > 0);
}
catch (Exception e) {
// TODO: handle exception
}
}
protected void onProgressUpdate(Integer... progress) {
mAdapter.notifyDataSetChanged();
}
#Override
protected void onPostExecute(Integer i) {
}
}
}
I try to replace the credential with the OAuth:
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setDebugEnabled(true);
cb.setOAuthConsumerKey("*************");
cb.setOAuthConsumerSecret("*************");
cb.setOAuthAccessToken("*************");
cb.setOAuthAccessTokenSecret("*************");
Didn't work..(I have all the correct keys and secrets)
I also tried to insert this whole part into one currently operational twitter client(I can get all the tweets on timeline and all), I don't know if I did it right but it didn't work either. Also in this case, if the Oauth was done again in this code and it worked, does that mean when I run the application I have to be redirected to the authorization page twice if I wanted to use this filter function? I would love a fix that the twitter feed can be used by both the timeline and this filtering mode.
Would anybody shed some lights on how I can do this?

Problem solved.
Here is the modified code:
protected Integer doInBackground(Integer... params) {
try {
DefaultHttpClient client = new DefaultHttpClient();
OAuthConsumer consumer = new CommonsHttpOAuthConsumer(CONSUMER_KEY,
CONSUMER_SECRET);
consumer.setTokenWithSecret(ACCESS_TOKEN, ACCESS_TOKEN_SECRET);
HttpGet request = new HttpGet();
request.setURI(new URI("https://stream.twitter.com/1/statuses/filter.json?track=" + mSearchTerm));
consumer.sign(request);
HttpResponse response = client.execute(request);
InputStream in = response.getEntity().getContent();
BufferedReader reader = new BufferedReader( new InputStreamReader(in) );
parseTweets(reader);
in.close();
}

How can i integrate my listview in above fragment?

If you want ListView in fragment then you'd be better off using your Fragment which would subclass ListFragment.
And the onCreateView() from ListFragment will return a ListView that you can populate.
http://developer.android.com/reference/android/app/ListFragment.html
http://www.vogella.com/tutorials/AndroidListView/article.html#listfragments
For Fragments, if you want a separate ListView and more in one fragment, it'l help if you go through:
http://www.easyinfogeek.com/2013/07/full-example-of-using-fragment-in.html
..for what is more to the layout and calling onCreateView()
Also, (not a part of the question, but from & for your code) if it helps, i'd suggest
Use a for each loop where you can instead of for(;;)
(in your case at: for each json child node in json main node)
http://docs.oracle.com/javase/1.5.0/docs/guide/language/foreach.html
How does the Java 'for each' loop work?

Also i am not able to Toast any of the message that i have kept in doInBackground(). Can you please help me solving this please...

You can't toast into doInBackground() because you can't update the UIview during the thread execution ! You should to use 'onProgress' and 'publishProgress'
change :
class AsyncData extends AsyncTask<String, Void, Void>
to:
class AsyncData extends AsyncTask<String, String, Void>
and override onProgress for toast:
#Override
protected void onProgressUpdate(String... values) {
super.onProgressUpdate(values);
if (values[0] != null)
Toast.makeText(UpcomingShow.this, values[0], Toast.LENGTH_SHORT).show();
}
And into doInBackground():
if(sc.equals("1"))
{
publishProgress(sc);
}
else
{
publishProgress("Fail.");
}

if(sc.equals("1"))
{
// posted successfully
Toast.makeText(UpcomingShow.this, sc, Toast.LENGTH_SHORT).show();
}
else
{
// error occurred
Toast.makeText(UpcomingShow.this, "Fail.", Toast.LENGTH_SHORT).show();
}
Remove this code form doInBackground
You can not update your UI on do in background , you can get result in onPostExecute and able to pop up those toast .

I tried sending a post your request through Postman(google extension) and the URL you've provided responded with HTTP Status 200 but without a response message. Problem is, based on the code provided, is that you're expecting a message response from the said url. You should probably check with the server you are connecting with.

While doing AsyncTask<String, Void, Void> Task you can’t achieve Toast display in Main thread, user Log.d(“TAG”,”your-text”);
You can achieve Toast in onPostExecution()
}catch (Exception e)
{
e.printStackTrace();
}
return sc;
}
protected void onPostExecute(Void result) {
super.onPostExecute(result);
if (pDialog != null && pDialog.isShowing()) {
pDialog.dismiss();
}
if(result.equals("1"))
{
// posted successfully
Toast.makeText(UpcomingShow.this, result, Toast.LENGTH_SHORT).show();
}
else
{
// error occurred
Toast.makeText(UpcomingShow.this, "Fail.", Toast.LENGTH_SHORT).show();
}
}
}

You can use the built-in org.json classes to convert the retrieved string (your text variable content) in to JSON objects.
Have a look at the tutorial from Lars Vogel on how to do that.

android text not visible

I am sending some information from my application to server and waiting for the response. Before i send i set my textview for message to display "processing request" and after getting response i display a different message.
This processing message is not getting displayed. Is it beacuse the UI is getting blocked due to other operation.
How to handle this. Threading is not giving correct result as need to display the response.
SO that involve UI in the thread .

You should not perform HTTP-work on the UI-thread. Instead use AsyncTask
In your AsyncTask you are only allowed to update the UI in two places:
#Override
protected void onPreExecute()
TextView.setText("Beginning HTTP-work..Please wait");
{
and
#Override
protected void onPostExecute(Void v) {
TextView.setText("Done..SUCCESS!");
}
Use these two to update the UI before and after the HTTP-work has been done.

Long operations must be in background. Best way to implement this on Android, use AsyncTask, for more information: http://developer.android.com/reference/android/os/AsyncTask.html
