Hi @Marion15,
Thank you for your first post here in the Roku Community!
We want to investigate your concern further. Are you trying to install the Roku application on your Android phone? If yes, what type of application are you trying to access? Is it the Roku mobile app or the Roku smart home app?
Please be advised that Apple iOS will not support the Android operating system since this is a separate software.
We look forward to hearing from you soon and gathering your details.
Thanks,
John
