我正在遵循许多指示,以从我的应用程序中发出简单的推文。我已经在Twitter上注册了它,但我就是不能发推文。我可以登录,但无法更新我的状态。这是登录的代码:
private void twitterLogOn() {
Twitter twitter = new TwitterFactory().getInstance();
try {
twitter.setOAuthConsumer(consumerKey, consumerSecret);
rToken = twitter.getOAuthRequestToken(myCallBack);
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(rToken.getAuthenticationURL())));
} catch (IllegalStateException e) {
// access token is already available, or consumer key/secret is not
// set.
if (!twitter.getAuthorization().isEnabled()) {
System.out.println("OAuth consumer key/secret is not set.");
finish();
}
} catch (Exception e) {
Toast.makeText(Configuration.this,getString(R.string.networkError), Toast.LENGTH_SHORT).show();
}
}
看起来运行良好,但是当我在登录后返回我的应用程序时,下一段代码应该被执行,结果始终以异常 Toast 结束。
public void onResume() {
super.onResume();
Uri uri = getIntent().getData();
if (uri != null) {
oauthVerifier = uri.getQueryParameter("oauth_verifier");
try {
Twitter tt = new TwitterFactory().getInstance(); // Do I need this new twitter instance?
tt.setOAuthConsumer(consumerKey, consumerSecret);
AccessToken at = tt.getOAuthAccessToken(rToken, oauthVerifier); // Gives the error
// Do tweet here ...
} catch (Exception e) {
Toast.makeText(Configuration.this, "Network Host not responding",Toast.LENGTH_SHORT).show();
}
}
}
有没有眼尖的人能告诉我哪里做错了?这行代码引发了异常。
AccessToken at = tt.getOAuthAccessToken(rToken, oauthVerifier);
提前致谢!
