【快应用】原生广告下载状态监听案例

news 2025/6/27 16:02:56

问题背景：

快应用中下载类原生广告监听下载状态变化接口调用没生效，在上报点击接口里触发下载监听后仅第一次返回状态，之后就不返回了，该如何处理？

问题分析：

快应用在1100版本新增了一个ad-button组件，废弃了原先的原生广告的下载类接口，改用ad-button自带的下载功能。因而在点击下载的时候开发者不知道该在何时去调用监听接口，往往都会在在nativeAd.reportAdClick()和nativeAd.reportAdShow()中调用的下载监听，这就导致出现此类似情况的时候。

解决方案：

ad-button在点击的时候就会跳转到广告页面并开启广告下载的，同时ab-button也是支持onclick点击事件的，可以把下载监听接口放到ad-button的点击事件中去。

代码：

<stack class="stackstyle" onclick="reportNativeClick()"><image if="native.isShowImg" class="img" src="{{native.adImgSrc}}"></image><ad-button class="adbtn" onclick="startButton()" valuetype="0" adunitid="{{native.adUnitId}}" adid="{{native.adData.adId}}"></ad-button></stack>

startButton(event) {console.error('start download result is = ', event.resultCode)nativeAd.onStatusChanged((data) => {console.log('onStatusChanged data = ', data)const progress = nativeAd.getDownloadProgress({adId: this.native.adData.adId})console.log('getDownloadProgress progress = ' + progress);const status = nativeAd.getAppStatus({adId: this.native.adData.adId})console.log('getAppStatus status = ' + status);})},
