Hey guys i am using twitter4J to post tweet on twitter

The problem is When i try to shift from main activity to twitter activity it show force close.
Main activity is = "MainActivity"
twitter activity is = "twiti_backup"
I think there is problem in Manifestfile but i dont know what was it.
public class twiti_backup extends Activity {
private static final String TAG = "Blundell.TweetToTwitterActivity";
private static final String PREF_ACCESS_TOKEN = "";
private static final String PREF_ACCESS_TOKEN_SECRET = "";
private static final String CONSUMER_KEY = "";
private static final String CONSUMER_SECRET = "";
private static final String CALLBACK_URL = "android:///";
private SharedPreferences mPrefs;
private Twitter mTwitter;
private RequestToken mReqToken;
private Button mLoginButton;
private Button mTweetButton;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.i(TAG, "Loading TweetToTwitterActivity");
setContentView(R.layout.twite);
mPrefs = getSharedPreferences("twitterPrefs", MODE_PRIVATE);
mTwitter = new TwitterFactory().getInstance();
mTwitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_SECRET);
mLoginButton = (Button) findViewById(R.id.login_button);
mTweetButton = (Button) findViewById(R.id.tweet_button);
}
public void buttonLogin(View v) {
Log.i(TAG, "Login Pressed");
if (mPrefs.contains(PREF_ACCESS_TOKEN)) {
Log.i(TAG, "Repeat User");
loginAuthorisedUser();
} else {
Log.i(TAG, "New User");
loginNewUser();
}
}
public void buttonTweet(View v) {
Log.i(TAG, "Tweet Pressed");
tweetMessage();
}
private void loginNewUser() {
try {
Log.i(TAG, "Request App Authentication");
mReqToken = mTwitter.getOAuthRequestToken(CALLBACK_URL);
Log.i(TAG, "Starting Webview to login to twitter");
WebView twitterSite = new WebView(this);
twitterSite.loadUrl(mReqToken.getAuthenticationURL());
setContentView(twitterSite);
} catch (TwitterException e) {
Toast.makeText(this, "Twitter Login error, try again later", Toast.LENGTH_SHORT).show();
}
}
private void loginAuthorisedUser() {
String token = mPrefs.getString(PREF_ACCESS_TOKEN, null);
String secret = mPrefs.getString(PREF_ACCESS_TOKEN_SECRET, null);
// Create the twitter access token from the credentials we got previously
AccessToken at = new AccessToken(token, secret);
mTwitter.setOAuthAccessToken(at);
Toast.makeText(this, "Welcome back", Toast.LENGTH_SHORT).show();
enableTweetButton();
}
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
Log.i(TAG, "New Intent Arrived");
dealWithTwitterResponse(intent);
}
@Override
protected void onResume() {
super.onResume();
Log.i(TAG, "Arrived at onResume");
}
private void dealWithTwitterResponse(Intent intent) {
Uri uri = intent.getData();
if (uri != null && uri.toString().startsWith(CALLBACK_URL)) { // If the user has just logged in
String oauthVerifier = uri.getQueryParameter("oauth_verifier");
authoriseNewUser(oauthVerifier);
}
}
private void authoriseNewUser(String oauthVerifier) {
try {
AccessToken at = mTwitter.getOAuthAccessToken(mReqToken, oauthVerifier);
mTwitter.setOAuthAccessToken(at);
saveAccessToken(at);
// Set the content view back after we changed to a webview
setContentView(R.layout.twite);
enableTweetButton();
} catch (TwitterException e) {
Toast.makeText(this, "Twitter auth error x01, try again later", Toast.LENGTH_SHORT).show();
}
}
private void enableTweetButton() {
Log.i(TAG, "User logged in - allowing to tweet");
mLoginButton.setEnabled(false);
mTweetButton.setEnabled(true);
}
private void tweetMessage() {
try {
mTwitter.updateStatus("Test - Tweeting with @Blundell_apps #AndroidDev Tutorial using #Twitter4j http://blog.blundell-apps.com/sending-a-tweet/");
Toast.makeText(this, "Tweet Successful!", Toast.LENGTH_SHORT).show();
} catch (TwitterException e) {
Toast.makeText(this, "Tweet error, try again later", Toast.LENGTH_SHORT).show();
}
}
private void saveAccessToken(AccessToken at) {
String token = at.getToken();
String secret = at.getTokenSecret();
Editor editor = mPrefs.edit();
editor.putString(PREF_ACCESS_TOKEN, token);
editor.putString(PREF_ACCESS_TOKEN_SECRET, secret);
editor.commit();
}
}
And here is Manifest
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/title_activity_main"
android:launchMode="singleInstance"
android:configChanges="orientation|screenSize">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".twiti_backup"
android:launchMode="singleInstance">

<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" /> <data android:scheme="android" android:host="callback_main" /> </activity>
<activity android:name=".MyTwite"/>
