onRemoteRequest

public boolean onRemoteRequest(int code,
                               MessageParcel data,
                               MessageParcel reply,

从类复制的说明: RemoteObject

Sets an entry for receiving requests.

This method is implemented by the remote service provider. You need to override this method with your own service logic when you are using IPC.

覆盖:

onRemoteRequest 在类中 RemoteObject

参数:

code - Indicates the service request code sent from the peer end.

data - Indicates the MessageParcel object sent from the peer end.

reply - Indicates the response message object sent from the remote service. The local service writes the response data to the MessageParcel object.

option - Indicates whether the operation is synchronous or asynchronous.

返回:

Returns true if the operation succeeds; returns false otherwise.

抛出:

RemoteException - Throws this exception if a remote service error occurs.
