Interstitials

Precautions#

  • Do not execute the ad loading method in the onAdLoadFailed callback, otherwise it will cause an infinite loop.
  • Do not directly execute the ad display method in the onAdLoaded callback. The SDK has an automatic ad refill function. If showInterstitialAd () is executed in the onAdLoaded callback, the developer will not be able to accurately control the timing of ad display.
  • Developers can refer to the interstitial.dart integration in the Demo

Integration steps#

1、Request Ads#

Map customMap = {};
Map localParams = {};
Map extraMap = TPInterstitialManager.createInterstitialExtraMap(
customMap: customMap,
localParams: localParams);
TPInterstitialManager.loadInterstitialAd("your unitId", extraMap: extraMap);

Parameter Description

unitId：The unitId created in the TradPlus backend#
  • Developers must fill in the information correctly. For example, if there are spaces before and after the unitId setting, the ad request will fail because the configuration cannot be pulled.
extraMap：Additional parameters#
  • customMap：Set Traffic Grouping Related attribute parameters
  • localParams：Set local parameters. Parameters that need to be set for individual advertising platforms.

2、Check if ads are available#

  • Developers call this method after listening to the onAdLoaded callback.
  • It is recommended that developers call this API to determine whether there are available ads before displaying ads, and then call the show method if there are ads.
  • true means there are available ads, false means there are no available ads for the time being
  • When calling interstitialAdReady and returns false, the sdk will request ads again, and the developer does not need to call the load method again.
bool isReady = await TPInterstitialManager.interstitialAdReady("unitId");

3、Enter the Ad scene#

TPInterstitialManager.entryInterstitialAdScenario("unitId", sceneId: "sceneId");

Parameter Description

sceneId ：ad scene ID#
  • Developers can create it in the TradPlus backend at the following location: Application Management - ad Scene.
  • For details on how to call, please refer to Description of the timing and purpose of calling advertising scenes。
  • When entering the advertising scene, pass in the sceneId. When displaying the advertisement, you also need to pass in the sceneId, otherwise it will affect the statistics.

4、Display ads#

TPInterstitialManager.showInterstitialAd("unitId",sceneId: "sceneId");

5、Listening callback#

Parameter Description

Basic callback#

listener = TPInterstitialAdListener(
onAdLoaded: (adUnitId, adInfo) {
// Ad loading successful
// You cannot call the show method to display ads in this callback
// V1.1.2 callback mechanism optimization, developers will call load once to get a corresponding loaded callback, no call will result in no callback
},
onAdLoadFailed: (adUnitId, error) {
// Ad loading failed
// You cannot call the load method again to request an ad in this callback, which will result in multiple invalid requests
},
onAdImpression: (adUnitId, adInfo) {
// Ad display
},
onAdShowFailed: (adUnitId, adInfo, error) {
// Ad display failed (partial ad support)
},
onAdClicked: (adUnitId, adInfo) {
//Ad clicked
},
onAdClosed: (adUnitId, adInfo) {
//Ad closed
},
oneLayerLoadFailed: (adUnitId, adInfo, error) {
// Ad source loading failed
// Do not call the load method again to request ads in this callback, which will result in multiple invalid requests
// During testing, developers can monitor this callback and obtain the reason for the failure to load each ad platform through error
}
);
TPInterstitialManager.setInterstitialListener(listener!);

other callback(optional)#

...
onAdStartLoad: (adUnitId, adInfo) {
// The callback returned each time the load method is called
},
onBiddingStart: (adUnitId, adInfo) {
// Bidding starts loading
},
onBiddingEnd: (adUnitId, adInfo, error) {
// Bidding loading is finished
// Configure bidding ad source to listen
// During testing, get the reason why bidding loading failed through error
},
oneLayerStartLoad: (adUnitId, adInfo) {
//Callback triggered before each layer of waterfall initiates a request to the third-party advertising source
},
oneLayerLoaded: (adUnitId, adInfo) {
// Configure multiple ad sources in the background, and each ad source will be called back once after loading successfully
},
onVideoPlayStart: (adUnitId, adInfo) {
// video start（supported by some ad sources）
},
onVideoPlayEnd: (adUnitId, adInfo) {
// video end（supported by some ad sources）
},
onAdAllLoaded: (adUnitId, isSuccess) {
// Status of the ad slot
// isSuccess returns true, indicating that an ad source has been successfully loaded for this request
// isSuccess returns false, indicating that all ad sources under the ad slot adUnitId have failed to load for this request
},
onAdIsLoading: (adUnitId) {
// New in V1.0.5
// If this callback is received after calling load, it means that the ad slot is still in the loading state and cannot trigger a new round of ad loading.
}

Download Kuaishou, ByteDance support (optional) (only supported by Android)#

...
onDownloadStart: (adUnitId, totalBytes, currBytes, fileName, appName) {
// Start download callback
// totalBytes: total file size (unit: bytes)
// currBytes: currently downloaded size (unit: bytes)
// fileName: file name
// appName: application name corresponding to the file
},
onDownloadUpdate: (adUnitId, totalBytes, currBytes, fileName, appName, progress) {
// Download progress update callback
// progress: download progress
},
onDownloadPause: (adUnitId, totalBytes, currBytes, fileName, appName) {
// Pause download callback
},
onDownloadFinish: (adUnitId, totalBytes, currBytes, fileName, appName) {
// Download completed callback
},
onDownloadFail: (adUnitId, totalBytes, currBytes, fileName, appName) {
// Download failed callback
},
onInstall: (adUnitId, totalBytes, currBytes, fileName, appName) {
//Apk installation completed callback
}
