save to shared preferences

[r3l4x-pt]

hi. whe a device is selected is it possible to save it to shared preferences so when the app is opened again it will try to connect with out scanning?
ive tried saving the device and then assign it to device but get app crash.
thank you

if u don't scan, u can save the device address and use BleManager#connect(String address, BleConnectCallback callback) to connect target devcie
