错误消息“java.net.SocketException: socket failed: EACCES (权限被拒绝)”
提问于 2012-06-30 17:58:53
我收到错误消息
java.net.SocketException:套接字失败: EACCES (权限被拒绝)
当我尝试应用下面的代码时。这是我调用的函数，并给出了这个异常。
public void run() {
// TODO Auto-generated method stub
URL myurl = null;
try {
myurl = new URL("http://10.0.2.2/list.JSON");
}
catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
URLConnection myconn = myurl.openConnection();
InputStream in = new BufferedInputStream(myconn.getInputStream());
InputStreamReader reader = new InputStreamReader(in);
BufferedReader br = new BufferedReader(reader);
String line;
StringBuilder sb = new StringBuilder();
while ((line=br.readLine()) != null)
{
sb.append(line);
//Toast.makeText(getApplicationContext(), "I enter here", Toast.LENGTH_LONG).show();
}
jsoncode = sb.toString();
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
threading = true;
super.run();

尝试使用，
<uses-permission android:name="android.permission.INTERNET"/>而不是,
<permission android:name="android.permission.INTERNET"></permission>Stack Overflow用户

试试这个：
<uses-permission android:name="android.permission.INTERNET"/>对于capital letters，您的activity names必须是这样的
<activity android:name=".Addfriend"/>
<activity android:name=".UpdateDetails"/>
<activity android:name=".Details"/>
<activity android:name=".Updateimage"/>Stack Overflow用户

试试看。
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
