By listening for back press events, the super app can capture the user's action of clicking the back button and then perform the specified operations. This topic introduces how to listen for the mini program back press event by implementing the specific interface of IAPMiniProgram SDK.

Procedures

To listen for the mini program back press event, complete the following steps:

Step 1: Implement GriverBackPressedPointEvent

Implement the GriverBackPressedPointEvent interface and write your business logic in the handleBackPressed method. Refer to the following sample on how to implement the interface.

public class DemoGriverBackPressedPointEvent implements GriverBackPressedPointEvent {
    
    @Override
    public void handleBackPressed(Page page) {
    }
    
    @Override
    public void onInitialized() {
        
    }
    
    @Override
    public void onFinalized() {
        
    }
}

For details about the interface, see GriverBackPressedPointEvent.

Step 2: Register back press event

Refer to the following sample code to call the registerEventHandler API to register the back press event after initializing the SDK.

Griver.registerEventHandler(new GriverEventManifest(DemoGriverBackPressedPointEvent.class.getName(), Arrays.asList(GriverBackPressedPointEvent.class.getName()), App.class));

For more information about the above API, refer to registerEventHandler.
