How to realize the function of the trap on mobile phone?

` private class SendTrap extends AsyncTask<Void, Void, Void> { protected Void doInBackground(Void... params) { PDUv1 pdu = new PDUv1(); pdu.setType(PDU.V1TRAP); pdu.setGenericTrap(PDUv1.COLDSTART); pdu.add(new VariableBinding(new OID(new int[]{ 1,3,6,1}),new Integer32(1995)));//1, 3, 6, 1, 2, 1, 1, 2

        // Specify receiver
        Address targetAddress = new UdpAddress("192.168.0.6/161");
        CommunityTarget target = new CommunityTarget();
        target.setCommunity(new OctetString("public"));
        target.setVersion(SnmpConstants.version1);
        target.setAddress(targetAddress);
        target.setRetries(2);
        target.setTimeout(1500);


        try {
            snmp.trap(pdu, target);
            Log.i(TAG, "doInBackground: !!!!!!!!!!!!!!!!!!");
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }
}

`

This is I use the Trap right?

I have already solved.SNMP trap (pdu, target) method cannot be used, although there is no error, but also send out, but cannot find send data on the server.I am the send by directly using SNMP (pdu, target) method, so you can receive.

The manager doesn't implement a listener for traps, so the Android device sends the trap but it's not received. SNMP4J seems to support traps, so implementing that should be simple. Take a look at this example.
