Tôi nhận được thông báo lỗi
java.net.SocketException: socket fail: EACCES (Quyền bị từ chối)
khi tôi cố gắng áp dụng mã dưới đây. Đây là chức năng tôi gọi và cung cấp cho tôi ngoại lệ này.
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();
}
