Tizen applications can communicate with each other using RPC Port APIs, which allows applications to send and receive data after a connection is established.
APIs will be used in generated source files by TIDLC which is an Interface Definition Language (IDL) compiler for Tizen. TIDL is recommended rather than using RPC Port APIs directly.
RPC Port APIs
RPC Port APIs compose of three set of APIs:
Proxy APIs: provide functions to connect a server, invoke functions in the server, and return the results from the server.
Stub APIs: provide the way to call methods of the server, which executes the methods requested by clients.
Parcel APIs: provide interfaces to marshall and unmarshall a parcel to/from the native type format.
Features of RPC Port API
Connection oriented communication
You must create a connection between the proxy and the stub applications to send and receive data. After the connection is disconnected, the callback for disconnected event that was registered earlier is called. Some other events such as connected and rejected events are supported as well.
The server application using stub APIs can register the privileges to verify whether the client that is trying to connect has proper privileges.
The server application using stub APIs can allow connections only if the proxy is signed with the required certificate.
To enable your application to use
To use the
rpc_port_proxy_connect() API, the application has to request permission by adding the following privilege to
<privileges> <privilege>http://tizen.org/privilege/appmanager.launch</privilege> <privilege>http://tizen.org/privilege/datasharing</privilege> </privileges>
- Tizen 4.0 and Higher for Mobile
- Tizen 5.0 and Higher for Wearable
