Below is my code for TwitterDialog calss. How can I solve this problem. Please give me a solution.

public class TwitterDialog extends Dialog { static final float[] DIMENSIONS_LANDSCAPE = { 460, 260 }; static final float[] DIMENSIONS_PORTRAIT = { 280, 420 }; static final FrameLayout.LayoutParams FILL = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT,ViewGroup.LayoutParams.FILL_PARENT); static final int MARGIN = 4; static final int PADDING = 2; private String mUrl; private TwDialogListener mListener; private ProgressDialog mSpinner; private WebView mWebView; private LinearLayout mContent; private TextView mTitle; private static final String TAG = "Twitter-WebView"; public TwitterDialog(Context context, String url, TwDialogListener listener) { super(context); mUrl = url; mListener = listener; } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mSpinner = new ProgressDialog(getContext()); mSpinner.requestWindowFeature(Window.FEATURE_NO_TITLE); mSpinner.setMessage("Loading..."); mContent = new LinearLayout(getContext()); mContent.setOrientation(LinearLayout.VERTICAL); setUpTitle(); setUpWebView(); Display display = getWindow().getWindowManager().getDefaultDisplay(); final float scale = getContext().getResources().getDisplayMetrics().density; float[] dimensions = (display.getWidth() < display.getHeight()) ? DIMENSIONS_PORTRAIT: DIMENSIONS_LANDSCAPE;addContentView(mContent, new FrameLayout.LayoutParams((int) (dimensions[0] * scale + 0.5f), (int) (dimensions[1]* scale + 0.5f))); } private void setUpTitle() { requestWindowFeature(Window.FEATURE_NO_TITLE); Drawable icon = getContext().getResources().getDrawable(R.drawable.twitter_icon); mTitle = new TextView(getContext()); mTitle.setText("Twitter"); mTitle.setTextColor(Color.WHITE); mTitle.setTypeface(Typeface.DEFAULT_BOLD); mTitle.setBackgroundColor(0xFFbbd7e9); mTitle.setPadding(MARGIN + PADDING, MARGIN, MARGIN, MARGIN); mTitle.setCompoundDrawablePadding(MARGIN + PADDING); mTitle.setCompoundDrawablesWithIntrinsicBounds(icon, null, null, null); mContent.addView(mTitle); } private void setUpWebView() { mWebView = new WebView(getContext()); mWebView.setVerticalScrollBarEnabled(false); mWebView.setHorizontalScrollBarEnabled(false); mWebView.setWebViewClient(new TwitterWebViewClient()); mWebView.getSettings().setJavaScriptEnabled(true); mWebView.loadUrl(mUrl); mWebView.setLayoutParams(FILL); //mWebView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE); mContent.addView(mWebView); } private class TwitterWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { if (Constants.LOG)Log.d(TAG, "Redirecting URL " + url); if (url.startsWith(TwitterApp.CALLBACK_URL)) { mListener.onComplete(url); //mWebView.getSettings().setAppCacheEnabled(false); //mWebView.refreshDrawableState(); if (Constants.LOG)Log.d(TAG, "Clearing chache"); TwitterDialog.this.dismiss(); return true; } else if (url.startsWith("authorize")) { return false; } return true; } @Override public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { if (Constants.LOG)Log.d(TAG, "Page error: " + description); super.onReceivedError(view, errorCode, description, failingUrl); mListener.onError(description); TwitterDialog.this.dismiss(); } @Override public void onPageStarted(WebView view, String url, Bitmap favicon) { if(Constants.LOG)Log.d(TAG, "Loading URL: " + url); super.onPageStarted(view, url, favicon); mSpinner.show(); } @Override public void onPageFinished(WebView view, String url) { super.onPageFinished(view, url); String title = mWebView.getTitle(); if (title != null && title.length() > 0) { mTitle.setText(title); } mSpinner.dismiss(); } } }``

To solve this problem, you need to force login

So just add force_login = true to the twitter authorization url.

I mean just change the following line of code in the TwitterApp.java class (if you have a class file with a different name and then search in your project using DefaultOAuthProvider )

 mHttpOauthprovider = new DefaultOAuthProvider("http://twitter.com/oauth/request_token", "http://twitter.com/oauth/access_token", "http://twitter.com/oauth/authorize?force_login=true"); 

after adding force_login = true, the problem with loading the web browser will be resolved, but every time you need to enter a username and password.

I was stuck all day to solve this problem.
