Hi Minh,
Thank you for getting back to us on this.
With regard to the use case that you're describing, I'm afraid this is not yet supported by the SDK. By default the SDK will open a browser (advertiser's landing page) once the Clickthrough URL has been triggered.
Just to clarify, since you're using the IMA SDK for Android, are you referring to Play store for Android and not the App store for iOS?
Regards,
