Get Twitter Followers List
I am developing an Android app to get Twitter followers. The following code is used for authentication and I have successfully logged in.
consumer = new CommonsHttpOAuthConsumer(
key,
secret);
CommonsHttpOAuthProvider provider = new CommonsHttpOAuthProvider(
"http://twitter.com/oauth/request_token",
"http://twitter.com/oauth/access_token",
"http://twitter.com/oauth/authorize");
String authUrl = provider.retrieveRequestToken(consumer,
TWITTER_CALLBACK_URL);
Log.e("Twittwer ", "Please authorize this app!");
startActivity(new Intent(Intent.ACTION_VIEW,
Uri.parse(authUrl)));
To get the list of subscribers I used the below code but I got an error and is attached to logcat
AccessToken accessToken = new AccessToken(consumer.getToken(),
consumer.getTokenSecret());
ConfigurationBuilder builder = new ConfigurationBuilder();
builder.setOAuthConsumerKey(key);
builder.setOAuthConsumerSecret(secret);
Configuration conf = builder.build();
twitter = new TwitterFactory(conf).getInstance();
twitter.setOAuthAccessToken(accessToken);
IDs followersId = twitter.getFollowersIDs(twitter.getId());
do {
for (long i : followersId.getIDs()) {
System.out.println("follower ID #" + i);
System.out.println(twitter.showUser(i).getName());
System.out.println(twitter.showUser(i)
.getProfileImageURL());
System.out.println(twitter.showUser(i).getURL());
}
} while (followersId.hasNext());
} catch (TwitterException e) {
System.out.println("e........"+e.getMessage());
e.printStackTrace();
}
LogCat:

What is the problem in this code. I read in some post that for checking the timestamp in the emulator. But the time and date in the emulator is correct. Please provide me with some help. Thanks in advance.
[EDIT] Am I this right?

In my project I have this code to get followers. Perhaps the main point has to do with use AsyncTask
.
if (twitter == null){
ConfigurationBuilder builder = new ConfigurationBuilder();
Configuration conf = builder
.setOAuthConsumerKey(CONSUMER_KEY)
.setOAuthConsumerSecret(CONSUMER_SECRET)
.setOAuthAccessToken(oAuthAccessToken)
.setOAuthAccessTokenSecret(oAuthAccessTokenSecret)
.build();
twitter = new TwitterFactory(conf).getInstance();
}
new AsyncTask<Void, Void, Void>() {
@Override
protected Void doInBackground(Void... params) {
long lCursor = -1;
AccessToken accessToken = new AccessToken(oAuthAccessToken, oAuthAccessTokenSecret);
long userId = accessToken.getUserId();
try {
IDs followersIDs = twitter.getFollowersIDs(userId, lCursor);
do {
for (long i : friendsIDs.getIDs()){
Log.d("follower ID #", String.valueOf(i));
}
}while(followersIDs.hasNext());
} catch (TwitterException e) {
Log.i("fetchFollowers", e.getErrorMessage());
}
return null;
}
@Override
protected void onPostExecute(Void param) {
}
}.execute();
