Doesn't that break security if you store your own fingerprint information?
I'm reading https://source.android.com/docs/security/features/biometric since it's a good project and primer on Android Biometrics.

biometric HAL guidelines to ensure that biometric data is not leaked and is removed when a user is removed from a device:

At first reading of your subject it appears you are attempting to break the basic security system.

Sorry but I was unclear. If you read the article noted it notes that by design the systems do not allow storing the fingerprint in external databases.

Now it's quite possible you have your reasons to do this but the system is designed to stop you. The times I encounter folk that want to break the security like this often has them very upset they can do what they want to do.

-> Moving on. Since a smartphone is a personal device, why would we need the biometric data in the external database? It's not like it will be useful in other phones.

I do have a background in the design and more for access systems such as what you might see at HID Global and more. I did design and coding for various surveillance equipment companies for many years.

But you are fighting a system that isn't supposed to allow export of the fingerprint data. As such you have chosen a dead end.

And then you write a comment but the sentence is cut off so I can't guess what you are trying to do. Try making a complete sentence so I can get a good grasp of what the project is about.

-> But let's also cover MDM which https://en.wikipedia.org/wiki/Mobile_device_management spells out well enough. If you are trying to make your own MDM then you have a few years to build such a thing (I hope!)

You may want to do something but the stock fingerprint API (biometrics) doesn't appear to offer such.

If you did manage to get around all that, someone will report the exploit and soon, Google will patch it out.

However if you want to make your own Access Control system with the usual fingerprint readers such as https://www.ibm.com/docs/en/samfess/8.2.0?topic=authentication-integrating-digitalpersona-fingerprint-reader (one of dozens of readers out there) then you won't be fighting with the Android concepts of biometrics.

Fingerprints (and other metrics) should be leak-proof. Thats basic security.

The hypocrisy of Google is horrendous, though. They say things likme biometrics should be leak-proof and at the same time they store this kind of data in least secure way possible.

Good riddance.

You will need a OkHttp library and server side API to handle database operations. and some additions in AndroidManifest.xml file. thats a bit lengthy process i specific expert would more guide you better on this
