StartActivity? That is as far as I know related to B4A. Are you sure you did post your question in the right forum? This is about B4J. Once this is sorted out it will be easier to help you. Erel can help you move your question in case it concerns B4A. For B4J you can use a backend service like PHP on serverside to perform this, and use OkHTTP library or later to communicate with the script. I hope this solves your problem.
