任何人都可以使用 OAuth 在 Android + Twitter 集成中提供帮助。
当我发布状态更新时，我已经在http://github.com/brione/Brion-Learns-OAuth上工作并收到下面列出的错误...

我成功通过 OAuth 身份验证并获取 user_secret 和 user_token 并存储在首选项中......
所以问题在于使用 OAuth 标头的 http 发布......
我的 Http Post 方法如下：
private class PostTask extends AsyncTask<String, Void, JSONObject> {
ProgressDialog postDialog;
@Override
protected void onPreExecute() {
postDialog = ProgressDialog.show(BLOA.this,
getText(R.string.tweet_progress_title),
getText(R.string.tweet_progress_text), true, // indeterminate
// duration
false); // not cancel-able
}
@Override
protected JSONObject doInBackground(String... params) {
JSONObject jso = null;
try {
HttpPost post = new HttpPost(
"http://twitter.com/statuses/update.json");
LinkedList<BasicNameValuePair> out = new LinkedList<BasicNameValuePair>();
out.add(new BasicNameValuePair("status", params[0]));
post.setEntity(new UrlEncodedFormEntity(out, HTTP.UTF_8));
post.setParams(getParams());
// sign the request to authenticate
mConsumer.sign(post);
String response = mClient.execute(post,
new BasicResponseHandler());
jso = new JSONObject(response);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (OAuthMessageSignerException e) {
e.printStackTrace();
} catch (OAuthExpectationFailedException e) {
e.printStackTrace();
} catch (OAuthCommunicationException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
} finally {
}
return jso;
}
// This is in the UI thread, so we can mess with the UI
protected void onPostExecute(JSONObject jso) {
postDialog.dismiss();
if (jso != null) { // authorization succeeded, the json object
// contains the user information
mEditor.setText("");
mLast.setText(getCurrentTweet(jso));
} else {
mLast.setText(getText(R.string.tweet_error));
}
}
}
