The official Roku app for Android primarily provides an app you can use to control Roku devices connected to the same local network as the device running the Roku app. It also can display The Roku Channel.
Some individual channels, including a separate The Roku Channel app, have their own Android apps you can install and run on an Android device. Otherwise you cannot stream content from your Roku to Android devices.
Owners of the program content sell licenses to distribute their material to various regions, via various providers, for various periods of time. All Roku devices can be used anywhere but the content available to view will vary from region to region and may be very sparse in some locations.
In addition the owners of the various channels must create Roku-compatible versions of their channel apps and supply them to Roku, specify the regions in which they may be used, and maintain a carriage agreement with Roku.
If your Roku account is based in your home region you may find that some of the programming you can receive at home is not available to you in other regions. Likewise you may not be able to view material that is available to people with accounts based in that region.
