This app works with the Live Channels on Android & Google TV , the app will list free news channels that are free and available to the public those streams are legal and free to use but do check the tv laws in your area .
The app scrapes few streams for tv and radio and can add more on request when I have time during playlist updates.

example : https://www.aljazeera.com/live/ and many more

Once installed the app either downloads or open the live channels and select News tv in the source then scan if it fails depending on your version of android go straight to the live channels and do it from there .
