几天来我一直在尝试如何解决我的问题，但我没有成功。

我只是想执行 RESTlet HTTPS 请求。代码很简单，因为我只有一个 acritivity：

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    System.setProperty("java.net.preferIPv6Addresses", "false");

    Engine.getInstance().getRegisteredClients().clear();
    Engine.getInstance().getRegisteredClients().add(new HttpsClientHelper(null));

    System.out.println("VERIFICO IL TOKEN: ");
    ClientResource clientResource = new ClientResource(
            "https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=lalala");

    Representation rep = clientResource.get();
}

restlet给出的原因是：

Caused by: Communication Error (1001) - Error while processing a connection

原因：

Caused by: java.lang.NullPointerException
at org.apache.harmony.xnet.provider.jsse.ClientSessionContext$HostAndPort.hashCode(ClientSessionContext.java:214)
at java.util.HashMap.put(HashMap.java:393)

我在网上读到它是一个 android 错误，但我找不到任何解决方法

任何想法？我正在使用 Restlet 2.1 RC5

尽管您致电：

Engine.getInstance().getRegisteredClients().clear();
Engine.getInstance().getRegisteredClients().add(new HttpsClientHelper(null));

您应该确保尝试这样做：

Engine.getInstance().getRegisteredClients().clear();
Engine.getInstance().getRegisteredClients().add(new org.restlet.ext.net.HttpClientHelper(null));
