Hello,

We had a bit of vacation situation in here. Hope you are doing fine.

Please, check out nRF Blinky app for a reference how to set up BLE Library. In app's build.gradle it sets dependency to ble library:
https://github.com/NordicSemiconductor/Android-nRF-Blinky/blob/2f3a06bf0e0c62a8172ac7fe2d872ac62ec19d84/app/build.gradle#L53 (actually to ble-livedata, which is an extension to it).

Then, follow this class: https://github.com/NordicSemiconductor/Android-nRF-Blinky/blob/master/app/src/main/java/no/nordicsemi/android/blinky/profile/BlinkyManager.java where the manager is implemented.

We recommend using the latest version of the BLE library, which is now 2.2.3 (https://github.com/NordicSemiconductor/Android-BLE-Library/).

If you need more assistance, please state your problem more clearly and provide some logs.
