Android Question Using Android API with Basic4Adroid

Hi,
I have the following problem:
I have a bluetooth printer with an Android API.
And I have a Clock, which can connet with bluetooth to an Android device. Also for this device I have an Android API.
I want to use both devices with B4A - is it possible to use a "standard" API for Android in B4A??

if this is possible, may be, a tutorial for this problem exists

Thanks for help
