我正在尝试在ProxyBusObject接口上调用远程AllJoyn方法，但出现ErrorReplyBusException。我似乎在API指南或参考文档中找不到与此有关的任何信息。任何帮助将非常感激。这是代码和错误日志。提前致谢。
private void connectToClient(String wellKnownName) {
mProxyObj = mBus.getProxyBusObject(wellKnownName, OBJECT_PATH, BusAttachment.SESSION_ID_ANY, new Class[]{MyBusInterface.class});
mMyBusInterface = mProxyObj.getInterface(MyBusInterface.class);
String test = mMyBusInterface.doSomething();
if (test == null) {
Log.i(TAG, "Null");
} else {
Log.i(TAG, test);
}
}
错误日志：

最佳答案
错误是因为总线不知道应该创建哪个ProxyObject，因为总线没有连接到任何BusObject。
这是因为您需要在调用代理对象之前加入会话。致电status = mBus.joinSession(busName, port, sessionID, sessionOpts, new SessionListener());
并在调用getProxyObject方法和其他方法之前检查加入会话的状态。
