java - SocketException: EACCESS (Permission denied) -

i'm trying create socket in android, keep on getting eaccess (permission denied) errors.

here code in separate thread ui thread.

public class client implements runnable {     private final static string server_address = "173.246.12.125";      @override     public void run() {         try {             inetaddress serveraddr = inetaddress.getbyname(server_address);             datagramsocket socket = new datagramsocket();             ... 

my android permissions include:

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

and because of stackoverflow answers, added well:

    <permission android:name="android.permission.internet"/> 

but still cannot create socket.

what missing? error output:

 java.net.socketexception: socket failed: eacces (permission denied)         @ libcore.io.iobridge.socket(iobridge.java:623)         @ java.net.plaindatagramsocketimpl.create(plaindatagramsocketimpl.java:93)         @ java.net.datagramsocket.createsocket(datagramsocket.java:157)         @ java.net.datagramsocket.<init>(datagramsocket.java:80)         @ java.net.datagramsocket.<init>(datagramsocket.java:65)         ...  caused by: android.system.errnoexception: socket failed: eacces (permission denied)         @ libcore.io.posix.socket(native method)         @ libcore.io.blockguardos.socket(blockguardos.java:282)         @ libcore.io.iobridge.socket(iobridge.java:608)          @ java.net.plaindatagramsocketimpl.create(plaindatagramsocketimpl.java:93)         @ java.net.datagramsocket.createsocket(datagramsocket.java:157)         @ java.net.datagramsocket.<init>(datagramsocket.java:80)         @ java.net.datagramsocket.<init>(datagramsocket.java:65)         @ com.austinfathman.traffic_server.client.run(udp.java:73)         @ java.lang.thread.run(thread.java:818) 

i getting similar error. turns out if try bind port in use, won't work.

datagramsocket socket = new datagramsocket(3996); 

this worked me.
