`DeadObjectException` 表示调用的对象已经被销毁。在 RxAndroidBle 中,这个异常通常出现在 `RxBleConnection` 对象已经被释放(如断开连接)后,仍然在尝试使用该对象时发生。
一种常见的情况是在使用 `Observable` 时,如果 `RxBleConnection` 对象已经被释放,那么错误就会出现。为了避免这种情况,建议在使用 `Observable` 之前,检查 `RxBleConnection` 对象是否仍然可用,如果不可用,需要重新建立连接。
另外,如果你已经断开了连接,而你仍然在尝试使用 `RxBleConnection` 对象,那么你需要在使用前重新建立连接。你可以使用 `RxBleDevice.establishConnection()` 方法重新建立连接。
最后,如果以上的解决方案都不能解决问题,你可以尝试重新安装应用程序或重新启动设备。

DeadObjectException是Android中的一个异常类,表示尝试访问已经被销毁的对象。这通常发生在与系统服务通信时,如果服务进程崩溃或被杀死,客户端进程就会收到这个异常。这个异常通常需要在代码中进行处理,以确保应用程序的稳定性和可靠性。
DeadObjectException
DeadObjectException is an exception in the Android operating system that occurs when a client attempts to invoke a method on a remote object that has already been destroyed. This can happen when the remote object is associated with a service or a binder, and the underlying process or service has been terminated or crashed.
When this exception occurs, the client can no longer communicate with the remote object and must re-establish the connection or request a new instance of the object. This exception is often seen in cases where the client and the remote object are running in separate processes, and there is a communication issue between them.
To handle this exception, the client can catch the DeadObjectException and take appropriate action, such as re-establishing the connection or requesting a new instance of the object. In some cases, the client may need to restart the remote service or the entire application to resolve the issue.
