Reference TV App Building

[ByteEvo Ltd.]

The documentation here states that when building the Live TV app, one needs to:

1. use the master branch when targeting Android 7.0 or newer. 

2. use the android-live-tv when for targeting Android 6.0.

Question:  Should I be able to build the Live TV app using android-live-tv branch on Android 10?  i.e., use newer Android but still the old branch, android-live-tv.

Here is error I am getting when building:
