android - Linkedin : oauth. signpost.exception.OAuthCommunicationException:与服务提供商的通信失败:null

Question

我将在我的 Android 应用程序中访问 linkedin 个人资料。我使用了下面的代码，它在安卓设备上运行良好，但在模拟器上崩溃了。不知道哪里出了问题。我的代码如下。

配置.java

public class Config {

    public static String LINKEDIN_CONSUMER_KEY = "75rbbjsc94argh";
    public static String LINKEDIN_CONSUMER_SECRET = "G85WTKgcIijk4U6Yu";
    public static String scopeParams = "rw_nus+r_basicprofile+r_fullprofile+r_emailaddress+r_network+r_contactinfo+rw_groups+rw_company_admin";

    public static String OAUTH_CALLBACK_SCHEME = "x-oauthflow-linkedin";
    public static String OAUTH_CALLBACK_HOST = "callback";
    //public static String OAUTH_CALLBACK_URL = OAUTH_CALLBACK_SCHEME + "://" + OAUTH_CALLBACK_HOST;
    public static String OAUTH_CALLBACK_URL = "x-oauthflow-linkedin://callback";
}

LinkedInSampleActivity.java

public class LinkedInSampleActivity extends Activity {
    Button login;
    Button share;
    EditText et;
    TextView name;
    ImageView photo;
    public static final String OAUTH_CALLBACK_HOST = "litestcalback";

    final LinkedInOAuthService oAuthService = LinkedInOAuthServiceFactory
            .getInstance().createLinkedInOAuthService(
                    Config.LINKEDIN_CONSUMER_KEY,Config.LINKEDIN_CONSUMER_SECRET, Config.scopeParams);
    final LinkedInApiClientFactory factory = LinkedInApiClientFactory
            .newInstance(Config.LINKEDIN_CONSUMER_KEY,

Answer 1

在 onCreate() 中的 setContentView() 之后添加以下函数。

    if (android.os.Build.VERSION.SDK_INT > 9) {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); StrictMode.setThreadPolicy(policy);
        }

这对我有用。希望它对你有用。
