What does {isTrusted: false} event message means?

Event.isTrusted is a part of the Web API, false indicates that the event was created or modified by a script or dispatched via dispatchEvent().

Why does the "close button" on my interstitial not work?

Sometimes you can't close an interstitial by using the "close button" and this can be caused by several both serverside and clientside issues.

One of the most common reasons for this unwanted behaviour is a setting in your config.xml preferences file.

Be sure to have the KeepRunning preference set to true (default), becausing turning this off (false) can freeze an interstitial when viewed.

The reason for this is that those type of ads are layered "above" the main app and can't be "reached" (interacted with) when the app stops running after leaving it's view.

Setting KeepRunning to true resolves the issue, but can have some negative inpact on battery usage and ofcourse all the existing (java-)scripts keep running in the background when the app is tombstoned.

Why do old browsers / devices throw an "Uncaught SyntaxError"?

The examples for this plug-in are using a syntax introduced in ES6 (ECMAScript version 6).

Some of those ES6 features are async, promise and await which makes development a lot easier and result in a more stable product. Almost every browser or device since 2015 does support ES6, but older versions don't.

So if you are targetting devices like Android 4.x or even Android 5.x a syntax error in the script can occur and throw messages in the console like Uncaught SyntaxError: Unexpected token function (async).

If you need to support those older devices, you can savely rewrite the example code to basic Javascript, without any of those asynchronous functions.

How to use different adUitId for Android and iOS?

It is best to replace adUitId during build time for different platforms, to avoid putting both adUitIds in the final app binary.

However, if that is not a concern, cordova.platformId can be used to determine which platform is running on.

Here is a simple example function to get adUnitId depends on the current platform,

function getAdUidId(android, ios) {
switch (cordova.platformId) {
case 'android':
return android
case 'ios':
return ios

Should I use Apple’s ATT prompt?

As part of iOS 14, you may choose to employ the new AppTrackingTransparency (ATT) framework by calling admob.requestTrackingAuthorization().

If your app is not using ATT, you need to state that during submission or your app may be rejected.

If your app integrates AppTrackingTransparency, please indicate where in your app we can find the AppTrackingTransparency permission request.

If your app does not integrate AppTrackingTransparency, please indicate this information in the Review Notes section for each version of your app in App Store Connect when submitting for review.

How to fix error Origin null is not allowed by Access-Control-Allow-Origin?

Add the following to config.xml,

<preference name="scheme" value="app" />
<preference name="hostname" value="localhost" />
