Falls on bind () in native?

Question

Android

I write the following native code:

sock = socket(AF_INET, SOCK_DGRAM, 0);<br>
    if(sock < 0) return false;<br>
    <br>
    addr.sin_family = AF_INET;<br>
    addr.sin_port = htons(UDP_PORT);<br>
    addr.sin_addr.s_addr = htonl(INADDR_ANY);<br>
<br>
    if(bind(sock, (struct sockaddr *)&addr, sizeof(addr)) < 0) return false;<br>
<br>
...//читаем из сокета данные<br>

Falls on bind - 'Permission denied'
If set addr.sin_addr.s_addr is known to be correct - 'Cannot assign requested adress'

Answer 1

memset for addr done?

Answer 2

Try to change addr.sin_addr.s_addr to a real IP or at least loopback
Does it work on Windows/Linux?

Answer 3

Forgotten in the manifest
<uses-permission android:name="android.permission.INTERNET" />
?

Answer 4

May be

sock = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP);
