java - Android 连接到 MJPEG 流 - 权限被拒绝错误

Question

我正在使用这段代码:

public static MjpegInputStream read(String url) {
    HttpResponse res;
    DefaultHttpClient httpclient = new DefaultHttpClient();   
    httpclient.getCredentialsProvider().setCredentials(
            new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT),
            new UsernamePasswordCredentials("admin", "1234"));
    try {
        res = httpclient.execute(new HttpGet(URI.create(url)));
        return new MjpegInputStream(res.getEntity().getContent());              
    } catch (ClientProtocolException e) { Log.e("MjpegInputStream - CP", e.getMessage()); } 
    catch (IllegalArgumentException e) { Log.e("MjpegInputStream - IA", e.getMessage()); } 
    catch (IOException e) { Log.e("MjpegInputStream - IO", e.toString() + " " + e.getMessage()); } 
    return null;
}

我得到IOExcetion:

04-09 17:27:52.350: E/MjpegInputStream - IO(5749): java.net.SocketException: Permission denied Permission denied

我的 URL 是 http://192.168.1.113/videostream.cgi 当我连接浏览器时，用户名和密码是 (admin, 1234 )

我做错了什么？

更新:

我添加了 INTERNET 权限，现在我的应用程序在这一行崩溃了:

res = httpclient.execute(new HttpGet(URI.create(url)));

带有NetworkOnMainThreadException

你好像忘了加

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

到您的 list 文件。

另见 Security and Permissions
