android - 无法通过登录屏幕 LinkedIn。在将我的应用程序链接到 LinkedIn 时

Question

我一直在尝试从我的 Android 应用程序中集成 Login LInkedIn。到目前为止，我已经进行了搜索，但关于如何进行搜索的示例有限。但这个问题的一个很好的答案 Posting LinkedIn message from Android application给了我一个先机。

但是当我运行它时。它会将我带到登录屏幕，然后当我输入我的凭据并按“登录并允许”时，它会在浏览器中执行某些操作但没有任何反应。它既不登录也不返回我的应用程序。

这是我的代码:

final SharedPreferences pref = getSharedPreferences(OAUTH_PREF,
                MODE_PRIVATE);
        final String token = pref.getString(PREF_TOKEN, null);
        final String tokenSecret = pref.getString(PREF_TOKENSECRET, null);
        if (token == null || tokenSecret == null) {
            new AsyncTask<Void, Void, LinkedInRequestToken>() {

                @Override
                protected LinkedInRequestToken doInBackground(Void... params) {
                    return oAuthService.getOAuthRequestToken(OAUTH_CALLBACK_URL);
                }

                @Override
                protected void onPostExecute(LinkedInRequestToken liToken) {
                    final String uri = liToken.getAuthorizationUrl();
                    getSharedPreferences(OAUTH_PREF, MODE_PRIVATE)
                            .edit()
                            .putString(PREF_REQTOKENSECRET,
                                    liToken.getTokenSecret()).commit();
                    Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
                    startActivity(i);
                }
            }.execute();
        } else {
            showCurrentUser(new LinkedInAccessToken(token, tokenSecret));
        }final LinkedInOAuthService oAuthService = LinkedInOAuthServiceFactory
                .getInstance().createLinkedInOAuthService(CONSUMER_KEY,
                        CONSUMER_SECRET);

对不起，但也许使用 ASNE library和 asne-linkedin让你的生活更轻松？只需向您的项目添加依赖项:

dependencies {
...
    compile 'com.github.asne:asne-linkedin:0.2.0'
...
}

像这样设置和请求登录

socialNetwork.requestLogin();

并且您可以轻松添加另一个社交网络或其他请求...
