# Android examples

The Android sample programs and code snippets are available in _sample/android/_ in the
TrulyNatural installation directory.

See _~/Sensory/TrulyNaturalSDK/7.9.0-pre.0/sample/android/_

The samples are written in Java; the same `@aar` and APIs work
unchanged from [Kotlin][] (see
[API overview § Kotlin on Android](https://doc.sensory.com/tnl/7.8/api/overview.md#kotlin-on-android) for interop notes).
