Android update its repository android.support to androidX, so Nordic sample code of nRF_UARTv2.0 must do some editing to be a exectable code with the App,
Now we have met a trouble while migrating, ie, nRF_UARTv2.0 project fail to synchronize with Gradle because its API_level is much lower then the current SDK version, and result in build error, will Nordic provide a newly version nRF_UART to resolve the problem while migrating nRF_UARTv2.0 to androidX
Thank you!!
