Hi,
I'm from israel and want to purchase a Roku device.
I searched in roku TV & Channels and did not found my TV provider app.
Roku did not include Android App Store?
This is my TV app provider link:

First, Roku is not Android. Second, Roku is not officially supported in Israel, so channel/app availability will be severely limited. A Roku device will work anywhere, but what you can access will vary by location. Honestly, if you're not located in a supported region there are probably much better alternatives to a Roku device.
