4、 void onNewSession(String id, String session_id, String fromAddr);void onProvisional(String id);void onConnected(String id);自動生成Java一部：public interface IIMServiceCallback extends android.os.IInterface /* Local-side IPC implementation stub class. */public static abstract class Stub extends android.os.Binder implements org.siprop.pip.android.service.IIMServiceCallback private static final java.lang.String DESCRIPTOR = org.siprop.pip.android.service.IIMServiceCallback;/* Construct the stub at attac

6、on mConnection = new ServiceConnection() public void onServiceConnected(ComponentName className, IBinder service) mService = IIMService.Stub.asInterface(service); mService.registerCallback(mCallback);5/20/202218Service4/4Service側()Activity側()Activity側IADLStubs(実体)Service側IADLStubs(実体)Stub用、AIDL無名実装ServiceConnection#onServiceConnected実装Service側IADL実体受取。IMService.Stub.asInterface()Service側IADL実体受取mService.registerCallback(mCallback);正確、独自実装必要Service側IADLStubs(実体)Activity側IADLStubs(実体)5/20/202219So

7、cket1/利用可能TCP接続最大同時接続複数動ServiceActivity、生成以外操作出来！生成必要！Handler使用5/20/202220Socket2/3Agent(Socket待受保持)用変更対象、Hander用、Handler#sendMessage(Message)用。変更後：public void incomingINVITE(Call c, PIPRequest request) handler.sendMessage( handler.obtainMessage(0, 0, 0, new EventMessage(IMEvent.onNewSession, new Objectc.getCallId(), request); 変更前：public void incomingINVITE(Call c, PIPRequest request) listener.onNewSession(c.getCallId(), request); 5/20/202221Socket3/3Service内Handler生成、先選択変更Handler、Service生成時生成必要

8、#Service内private Handler mHandler = new Handler() Override public void handleMessage(Message handlerMessage) / EventMessage取出。 EventMessage msg = (EventMessage)handlerMessage.obj; Object objs = msg.getArgs(); / 種類、IMService先選択 switch (msg.getEventType() case onNewSession: / 引数共、 imService.onNewSession(String)objs0, (PIPMessage)objs1); break;(以下略)5/20/202222直接通信環境構築1/3qemutap機能利用OS上tap、OS(Android)NIC、OS側NIC使用機能5/20/202223直接通信環境構築2/31.Android上NIC設定書換1.etc/qemu-init.sh編集例：ifconfigeth1192.168.1.2netmask255.255.255.0uprouteadddefaultgw192.168.1.1deveth12.OStap設定例：brctladdbrbr0tunctl-u$USER-tnet_androidbrctladdifbr0eth0brctladdifbr0net_android3.Androidqemu起動変更$android_sdk/tools/emulator-console-qemu-netuser-netnic-netnic,vlan=1-netnic-nettap,vlan=1,ifname=net_android5/20/202224直接通信環境構築3/3LinuxZaurus上、Androidcortez氏、開発Zaurus上動作Android利用http:/ http:/noritsuna.siprop.org/
