When IAPMiniProgram SDK loads a URL, it uses WebView to load the page. If you want to open some URLs in your browser, you can intercept the URL navigation process of SDK by implementing the GriverUrlNavigationEvent interface. Each time when SDK loads a URL, it sends out the GriverUrlNavigationEvent interface and you can intercept it.

Procedures

To intercept for the mini program load url events, complete the following steps:

Step 1: Implement the GriverUrlNavigationEvent interface

Implement the GriverUrlNavigationEvent interface and write your business logic in the onStartUrlNavigationand allowLoadUrl method. Refer to the following sample on how to implement the interface.

class DemoGriverUrlNavigationEventHandler : GriverUrlNavigationEvent {
    override fun onStartUrlNavigation(page: Page?, url: String?): Boolean {
        return false
    }

    override fun allowLoadUrl(page: Page?, url: String?): Boolean {
        return false
    }

    override fun onInitialized() {
    }

    override fun onFinalized() {
    }
}

Step 2: Register the DemoGriverUrlNavigationEventHandler class

Call the registerEventHandler interface to register the URL navigation event after initializing the SDK. For details, see the following GriverUrlNavigationEvent interface.

Code sample:

Griver.registerEventHandler(
    GriverEventManifest(
        DemoGriverUrlNavigationEventHandler::class.java.name,
        Arrays.asList(GriverUrlNavigationEvent::class.java.name), Page::class.java
    )
)

Structures

GriverUrlNavigationEvent interface

The definition of the GriverUrlNavigationEvent interface is shown in the following code:

interface GriverUrlNavigationEvent : GriverEvent {
    
    fun onStartUrlNavigation(page: Page?, url: String?): Boolean


    fun allowLoadUrl(page: Page?, url: String?): Boolean
}

Based on the definition, this interface provides the following methods:
