You will need to create a launcher app or create an alternative way to launch a fullscreen URL when a SmartTV with Android P is powered on. To do this, you will need to create an app or launcher that is compliant with Android P and run normally on a SmartTV with the said version. You can also modify or build upon the existing source code, provided the valid license requirements are complied with. Depending on the Android API requirements necessary for the purpose, you will need to ensure that the API level meets those requirements. Additionally, you should also include the compatibility of the technical elements with the existing hardware configuration on the SmartTV. You can also include a fully customized user interface which is suitable for the purpose of the app/launcher. To ensure the full-screen display of the URL, it should be made sure that the code is designed in such a way that the URL can be launched in full-screen mode on the SmartTV. Once the app/launcher is completed, extensive testing should be done to ensure the reliable user experience.
