}
}
LoginAsync la = new LoginAsync();
la.execute(username, pass);
}
}

You can pass txtUser and Pass to invokeLogin();
so it look like invokeLogin(txtUser,Pass);
Then your invokeLogin method
public void invokeLogin(String username, String pass){
login(username,pass);
}

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;

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 {

request.setURI(new URI("https://stream.twitter.com/1/statuses/filter.json?track=" + mSearchTerm));
HttpResponse response = client.execute(request);

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);
}

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();

save your image url in db (if they are in a same folder on your host choose a base url and save only image name)
after fetching your data , there are alot of library for display images such as :
Picasso

http request and http response in android?

I am working on with:
org.apache.http.HttpResponse;
org.apache.http.client.HttpClient;
org.apache.http.client.methods.HttpGet;
org.apache.http.impl.client.DefaultHttpClient;
i am using jsp for writing server side code.
i am unaware of the procedure of sending some value to server from my emulator.
and get a value o a string from the server response.
I mean to say... what are the methods to be used? How to use them.?

To send a HTTP GET request and retrieve response:
private static void get(final Context context, final String url) {
new Thread() {
#Override
public void run() {
HttpClient client = new DefaultHttpClient();
HttpGet request = Utils.createHttpRequest(context, url, true, false);
setProxyIfNecessary(context, request);
try {
HttpResponse response = client.execute(request);
Log.v("Test", "StatusCode: " + response.getStatusLine().getStatusCode() + ", Entity: " + EntityUtils.toString(response.getEntity()));
} catch (Exception e) {
// Oh, crash
}
}
}.start();
}
private static void setProxyIfNecessary(Context context, HttpUriRequest request) {
ConnectivityManager connectivity = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connectivity == null ? null : connectivity.getActiveNetworkInfo();
if (networkInfo == null || networkInfo.getType() == ConnectivityManager.TYPE_WIFI) {
return;
}
String proxyHost = Proxy.getHost(context);
if (proxyHost == null) {
return;
}
int proxyPort = Proxy.getPort(context);
if (proxyPort < 0) {
return;
}
HttpHost proxy = new HttpHost(proxyHost, proxyPort);
ConnRouteParams.setDefaultProxy(request.getParams(), proxy);
}
Call it by:
get(context, "http://developer.android.com/index.html");
And you will get log by logcat *:S Test:V
Notice that the new thread is to avoid blocking UI thread

Below is a code i implemented for sending username and password from android to server side JSP page. The response from the server is a json object which is then processed.The code is as given below.

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
