Electronic device, method, and computer readable medium for dynamic layout message

An electronic device comprising:

• a memory configured to store instructions;
• a communication circuit;
• and
• at least one processor,
• wherein the at least one processor is configured to execute the instructions to control the electronic device to:
• obtain an RCS message comprising a first layout object, content objects under the first layout object, a second layout object under the first layout object, and other content objects under the second layout object, and transmit the obtained RCS message to an external device through the communication circuit,
• wherein the first layout object is usable to determine relative positions of the content objects,
• wherein the second layout object is usable to determine relative positions of the other content objects,
• wherein each of the content objects and the other content objects is usable to provide a plurality of contents of the RCS message.

A non-transitory computer readable storage medium comprising one or more programs including instructions, wherein, when being executed by an electronic device including a touch screen, a communication circuit and at least one memory configured to store an application supporting an RCS, the instructions cause the electronic device to:

• receive an RCS message from an external device through the communication circuit using the application;
• identify whether the RCS message is a first type or a second type based on data included in a header of the RCS message;
• identify a first layout object from the RCS message based on identifying that the message is the first type;
• identify whether each of second objects under the first layout object is a content object or a layout object indicating relative positions of a plurality of contents provided by the content object to be displayed on the touch screen;
• and
• display the plurality of contents based on the relative positions identified based on the layout object.
