** 有了BinderProxy物件，myActivity彦就能呼叫BinderProxy的IBinder::transact()函?，咄而呼叫到myBinder的IBinder::onTransact()函?。也可藉由ibinderForJavaObject()可取得?物件相??的BpBinder物件。

提供斤您?考。

---- BinderProxy??是定柳於Android 框架的/java/Binder.java?案彦

final class BinderProxy implements IBinder {

public native boolean pingBinder();

public native boolean isBinderAlive();

public IInterface queryLocalInterface(String descriptor) {

return null;

}

public native String getInterfaceDescriptor() throws RemoteException;

public native boolean transact(int code, Parcel data, Parcel reply,

int flags) throws RemoteException;

public native void linkToDeath(DeathRecipient recipient, int flags)

throws RemoteException;

public native boolean unlinkToDeath(DeathRecipient recipient, int flags);

BinderProxy() {

mSelf = new WeakReference(this);

}

@Override

protected void finalize() throws Throwable {

try {

destroy();

} finally {

super.finalize();

}

}

private native final void destroy();

private static final void sendDeathNotice(DeathRecipient recipient) {

if (Config.LOGV) Log.v("JavaBinder", "sendDeathNotice to " + recipient);

try {

recipient.binderDied();

}

catch (RuntimeException exc) {

Log.w("BinderNative", "Uncaught exception from death notification",

exc);

}

}

final private WeakReference mSelf;

private int mObject;

}

其中，最重要的Native函?是：
