The latest version of the NCID Android app has been released into the Play store.
Newer Android versions (Oreo+) have had changes to increase battery life, so the stay-awake features have been removed because they were no longer doing anything.
Call logs will stay visible while disconnected, so that you can view them as long as the app stays in memory.
The Keep Alive function does a round-trip test on the server connection to make sure it is still working.
This release supports Android 4.2 to Android 10. For older devices, and to get the Call/SMS add-on, see the NCID Sourceforge repository.
