尝试从Android活动中公开Restlet服务

标签： android restlet

我正在尝试按如下方式创建Restlet服务（根据Restlet in Action书中的说明）：

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

        Component component = new Component();
        component.getServers().add(Protocol.HTTP, 8182);
        component.getDefaultHost().attachDefault(HttpListener.class);

        try {
            component.start();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

我的AndroidManifest.xml中的权限：

<uses-permission android:name="android.permission.INTERNET"/>
<permission android:name="android.permission.INTERNET"/>

我在build.gradle中的依赖项：

compile("org.restlet.jse:org.restlet:2.1-M7") {
    exclude group: 'org.osgi', module: 'org.osgi.core'
}
compile("org.restlet.jse:org.restlet.ext.simple:2.1-M7")
