How do I connect the Xbox app to my Xbox 360, is it even possible?

Hi Ben! I'm Rostom, an Independent Advisor. I will be glad to help you here.

The Xbox 360 support is no longer maintained. The Xbox app doesn't support linking your Xbox 360. It's only for Xbox One and later devices.

But, if I can't connect my xbox 360 to the internet, how do I download the app?

I'm trying to connect to Xbox live on my Xbox 360 to download apps however it's not letting me...even tho I am signed into my avatar on the Xbox? What can I do?

having the same issue. I have searched the forums and used google to try to search for a solution to no avail. my 360 is already set to allow smartglass app connection. I have reinstalled xbox 360 smartglass on my windows 8.1 machine (lenovo lynx K3 tablet).
the xbox 360 smartglass app on my android device (galaxy s3) can connect just fine. (had a similar issue with the xbox one smartglass app on my tablet, but found that to be a software firewall (comodo) issue. with the 360 smartglass app, I have tried disabling
the firewall and I still get a message the app cannot find the console). when I check the properties of the app in the task manager, it points to a folder of where it was installed, and not an executable. not sure if this is what is causing the issue. both
the 360 and the tablet (I have even been prompted by the app to re-sign in and I used the same account information)are signed in under the same account and are on the same wireless network. and again, I can sign into the xbox one smartglass app just fine after
I resolved the firewall issue (to allow the application associated with the app to be allowed connection). I have also reset my router (as I found other suggestions in other posts advise to do. I feel as I have exhausted every conceivable possibility, and
yet, still does not work. HELP!!!!

The Xbox app on windows 10 allows you to stream your Xbox to your Windows 10 PC to play on a local internet connection (LAN) with it.

It is not possible to play xbox 360 games on an android phone or Windows 7 professional. You can't even play them on Windows 10. You CAN play them via streaming to your xbox one that is playing the xbox 360 game and play on your Windows 10 PC though.

The Xbox Live app on your phone is for messages, videos, possibly parties and redeeming codes. That's all that it can do.
