首先。是否有可能添加facebook应用程序，如Facebook，Twitter？我已经阅读了很多博客，但无法在我的应用程序中实现linkedin。我已经达到用户输入其用户名和密码的应用程序的用户授权过程。但是当他输入一个5位数的数字进入屏幕并且屏幕被告知到了应用程序主屏幕。然后填写并按回车。
但问题是我如何从浏览器移回我的应用程序以及用户应该放置此数值数据的位置。而当＆amp;如何获取访问令牌以使用用户配置文件的数据。
在互联网上使用android没有好事。我得到了一个图书馆http://code.google.com/p/linkedin-j/，但是如何从情况中克服？不知道。谁能建议我一些解决方案。感谢。

您可以使用第三方jar scribe.jar实现此目的。 请按照以下方式调用webview意图进行授权。
OAuthService service = new ServiceBuilder()
.provider(LinkedInApi.class).apiKey(Constants.CONSUMER_KEY)
.apiSecret(Constants.CONSUMER_SECRET)
.callback(Constants.OAUTH_CALLBACK_URL).build();
Token liToken = oAuthService
.getRequestToken();
String url = oAuthService
.getAuthorizationUrl(PrepareRequestLinkedinTokenActivity.liToken);
Log.i(TAG, "Popping a browser with the authorize URL : " + url);
// Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(liToken
// .getAuthorizationUrl()));
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
context.startActivity(intent);
在授权时，您将被重定向到您的活动。按如下方式检索活动中的访问令牌。
@Override
public void onNewIntent(Intent intent) {
super.onNewIntent(intent);
SharedPreferences prefs = PreferenceManager
.getDefaultSharedPreferences(this);
final Uri uri = intent.getData();
if (uri != null
&& uri.getScheme().equals(Constants.OAUTH_CALLBACK_SCHEME)) {
Log.i(TAG, "Callback received : " + uri);
Log.i(TAG, "Retrieving Access Token");
new RetrieveAccessTokenTask(this, prefs).execute(uri);
finish();
}
}
public class RetrieveAccessTokenTask extends AsyncTask<Uri, Void, Void> {
private SharedPreferences prefs;
public RetrieveAccessTokenTask(Context context, SharedPreferences prefs) {
this.prefs = prefs;
}
/**
* Retrieve the oauth_verifier, and store the oauth and
* oauth_token_secret for future API calls.
*/
@Override
protected Void doInBackground(Uri... params) {
final Uri uri = params[0];
final Verifier verifier = new Verifier(
uri.getQueryParameter("oauth_verifier"));
try {
accessToken = service.getAccessToken(liToken, verifier);
final Editor edit = prefs.edit();
edit.putString(Constants.LINKEDIN_TOKEN, accessToken.getToken());
edit.putString(Constants.LINKEDIN_TOKEN_SECRET,
accessToken.getSecret());
edit.commit();
Log.i(TAG, "OAuth - Access Token Retrieved");
} catch (Exception e) {
Log.e(TAG, "OAuth - Access Token Retrieval Error", e);
}
return null;
}
@Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
executeAfterAccessTokenRetrieval(accessToken);
}
使用访问令牌，您可以按如下方式对linkedin进行网络更新。
private void postToLinkedin(String comment) {
SharedPreferences prefs = PreferenceManager
.getDefaultSharedPreferences(LinkedinDialogActivity.this);
String token = prefs.getString(Constants.LINKEDIN_TOKEN, "");
String secret = prefs.getString(Constants.LINKEDIN_TOKEN_SECRET, "");
Token accessToken = new Token(token, secret);
OAuthService service = new ServiceBuilder().provider(LinkedInApi.class)
.apiKey(Constants.CONSUMER_KEY)
.apiSecret(Constants.CONSUMER_SECRET)
.callback(Constants.OAUTH_CALLBACK_URL).build();
String url = "http://api.linkedin.com/v1/people/~/shares";
OAuthRequest request = new OAuthRequest(Verb.POST, url);
String payLoad = "<?xml version='1.0' encoding='UTF-8'?><share><comment>Check out the Sep 13 Second share!</comment><content><title>My new share with linked-in</title><description>Leverage the Share API to maximize engagement on user-generated content on LinkedIn</description><submitted-url>https://developer.linkedin.com/documents/share-api</submitted-url><submitted-image-url>http://m3.licdn.com/media/p/3/000/124/1a6/089a29a.png</submitted-image-url></content><visibility><code>anyone</code></visibility></share>";
request.addHeader("Content-Length", Integer.toString(payLoad.length()));
request.addHeader("Content-Type", "text/xml");
request.addPayload(payLoad);
service.signRequest(accessToken, request);
Response response = request.send();
System.out.println("response >>>> " + response.getBody());
}
活动应在清单文件中声明如下。
<activity android:name=".PrepareRequestLinkedinTokenActivity"
android:launchMode="singleTask" android:theme="@android:style/Theme.Translucent.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:host="callback" android:scheme="x-oauthflow-linkedin" />
</intent-filter>
</activity>

好的，几小时前我遇到了同样的问题，这就是我解决的问题：
public class WebFragment extends Fragment {
class MyJavaScriptInterface
{
public void processHTML(String html)
{
Log.e("HTML" , html);
((MainActivity)getActivity()).LinkedInCallback(html);
}
}
private WebView mWebView;
private String mUrl = "http://www.google.com";
boolean doneRedirect = false;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
LayoutInflater mInflater = (LayoutInflater) getActivity().getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
RelativeLayout view = (RelativeLayout) mInflater.inflate(R.layout.webview,null);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(1200, 700);
lp.addRule(RelativeLayout.CENTER_IN_PARENT);
view.setLayoutParams(lp);
mWebView = (WebView) view.findViewById(R.id.wv1);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.addJavascriptInterface(new MyJavaScriptInterface(), "HTMLOUT");
mWebView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Log.e("Should Override url" , url);
view.loadUrl(url);
return false;
}
@Override
public void onPageFinished(WebView view, String url)
{
if(url.contains("submit"))
view.loadUrl("javascript:window.HTMLOUT.processHTML(document.getElementsByClassName('access-code')[0].innerHTML);");
}
});
mWebView.loadUrl(mUrl);
return view;
}
public void loadUrl(String url) {
mWebView.loadUrl(url);
Log.e("loadUrl", url);
}
public void setUrl(String url) {
mUrl = url
Log.e("setUrl", url);
}
public String getUrl() {
return mUrl;
}
}
在我的活动方面我有这些方法：
private void login() {
new Thread(new Runnable() {
public void run() {
oAuthService = LinkedInOAuthServiceFactory.getInstance().createLinkedInOAuthService( CONSUMER_KEY, CONSUMER_SECRET);
factory = LinkedInApiClientFactory.newInstance( CONSUMER_KEY, CONSUMER_SECRET);
liToken = oAuthService.getOAuthRequestToken();
loginFragment(liToken.getAuthorizationUrl());
}
}).start();
}
private void loginFragment(String url) {
mWebViewFragment.setUrl(url);
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.main_layout ,mWebViewFragment ,"webview");
fragmentTransaction.addToBackStack("webview");
fragmentTransaction.commit();
}
public void LinkedInCallback (final String VerifierCode)
{
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.remove(mWebViewFragment);
fragmentTransaction.commit();
new Thread(new Runnable() {
public void run() {
String verifier = VerifierCode;
LinkedInAccessToken accessToken = oAuthService.getOAuthAccessToken(liToken, verifier);
}
}).start();
}
只是为了澄清：
我创建了一个带有webview的片段，当用户输入他们的凭据时，我检测到包含“submit”的重定向url，并且我做了一些JavaScript注入以获取具有oauth验证器的元素。然后我解散该片段并返回到我的活动并使用该oauth验证器来使用客户端做我需要的。
