I want to use android fingerprint scanner to store fingerprints of my own in my android application not in device OS and later I want to compare them. and use them for other purposes. If there is a way to use android fingerprint scanner like this please let me know. Thanks.
The answer is NO. Fingerprints are highly confidential and Android does not allow users data or any form of processed or raw fingerprint data to leave the trusted environment (Mobile hardware). for more information you can read about Fingerprint HIDL.
