Hi, i am making a small android application which VoIP program based in SIP(Session Initiation Protocol) using the android default emulator(version : android 2.2) . Through this program, i will support the QoS for each service such as voice telephony, SMS messaging and so on. So, i want to mark the TOS field(8bit) in IP packet header to grant priority each service IP packets.
As you know, there is a method "setTrafficClass(int value)" in android UDP socket API. But, after capturing the packets using the wireshark, i could found that this API is not effect. In short, the UDP socket always sends packets with default IP TOS field, 0x00. Does anybody know why this problem case? Does android prohibit chaging IP header process on purpose? Plz, give me some advice about this problem. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
