Introduction

This sample shows how to start an ability and use the Call function of the stage model, including starting another ability, creating a callee, and accessing the callee.

Usage

1. Start the demo app. The main ability is started, and Call Sample is displayed on the page.

2. Touch Start Callee Ability. Callee Ability is displayed on the page.

3. Switch to the MainAbility page and touch Obtain Caller to obtain the caller interface. The main ability is the caller, and the callee ability is the callee. This operation does not switch the Callee Ability page to the foreground.

4. In the text box below Enter message to send, enter a string, for example, "play music".

5. Touch Send Message Through Call to serialize the string entered and send the processed string to the callee. A message is displayed on the MainAbility page, indicating that the message is sent successfully. Switch to the Callee Ability page, and you can see the play music message sent by the caller.

6. Touch Release Caller to release the caller interface. After the caller is released, the main ability cannot send data to the callee ability.
