我的应用程序有3个活动A,B,C.活动A调用B.在B中,我调用Intent.ACTION_VIEW对Twitter进行身份验证,如下所示:
public static void DoAuthen(Context context, String CallBackUrl) throws OAuthMessageSignerException, OAuthNotAuthorizedException,
OAuthExpectationFailedException, OAuthCommunicationException {
httpOauthConsumer = new CommonsHttpOAuthConsumer(context.getString(R.string.Twitter_ConsumerKey), context
.getString(R.string.Twitter_ConsumerSecret));
httpOauthprovider = new DefaultOAuthProvider("http://twitter.com/oauth/request_token", "http://twitter.com/oauth/access_token",
"http://twitter.com/oauth/authorize");
String authUrl = httpOauthprovider.retrieveRequestToken(httpOauthConsumer, CallBackUrl);
context.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(authUrl)));
}

验证后,我的应用程序在活动B回调.这里B调用C.现在,如果我按下返回按钮,它将导航到浏览器(以前用于通过Twitter进行身份验证),而不是B,然后是A.我怎么能解决这个?
