how to access to the fingerprint sensor
since this is possible in android studio (at least i've found the permission "use_fingerprint") i would like to know if it's possible to access to the sensor with processing

@erwrow===
add the permission to your manifest uses-permission android:name="android.permission.USE_FINGERPRINT"
I expressed myself wrong, how can i access what is scanning the sensor?
@erwrow -- I don't understand what you mean. The sensor does the scanning; nothing is scanning it.
Can you explain more, or use an example?
@erwrow===
supposing that your screen is locked, that permissin has been granted, that one fingerprint was registered, you have only to generate a key and a cipher, then use the android API for managing what you want: FingerPrinterManager and its callbacks about authentification.
Be conscious that all "suppositions" can and must be verified by code.
more details about this API:

thanks @akenaton, i'll investigate that link!
