}

class MyActivity : Activity() {
    private lateinit var devicePerformance: DevicePerformance
    override fun onCreate(savedInstanceState: Bundle?) {

        devicePerformance = (application as MyApplication).devicePerformance
    }

    override fun onResume() {
        super.onResume()
        when {
            devicePerformance.mediaPerformanceClass >= Build.VERSION_CODES.TIRAMISU -> {
                // Provide the most premium experience for highest performing devices
