Code samples for testing with an Android feature and without

I am looking for an existing code sample which demonstrate a mobile native app testing which can work on a device which supports a specific feature while run OK on a device which doesn't. Let me explain: In the Android Manifest.MF file there would be a "uses-feature" section where developers would define "support Touch ID" as an example - i would like to see a test (TestNG/Junit) who can run on a Samsung S7 with this feature while run without it (using else/if etc.) on a Samsung S6

Thanks Ahead Eran
