Keepassdx: Fingerprint hardware not detected.

[p3yot3]

When attempting to use the fingerprint feature, I get a message saying: "Can not start this feature. The hardware is not detected".

All other apps work fine with fingerprint.

Android 6 (Mediatek)
Homtom HT20 Pro running Magisk 16.4

Typically, when the fingerprint recognition hardware is not recognized, the phone does not use the google recognition API but a proprietary system. Can you tell me the name of another downloaded application (preferably open source) for which the fingerprint works? (to see how it works)
I have to solve other problems related to the fingerprint keys, I'll do everything at the same time. #114

Magisk fingerprint works fine for SU confirmation & is also open source:

Other apps that work but are not open source are Authenticator Plus & Revolut. Let me know if you need any more info.

Working open source apps:
AndOTP - this one uses "Device authentication" which includes fingerprint if activated
Nextcloud (auth only)
Magisk (auth only)

I was able to use the fingerprint feature when running LineageOS but when I went back to OxygenOS (OnePlus 2 Official ROM) I see this error.

The Magisk code uses regular FingerprintManager and not FingerprintManagerCompat, I changed the compat classes. Tell me if this version works for you ? :
KeePassDX_TEST_2018071001.apk.zip

Yup - that works perfectly!

EDIT: When using the fingerprint feature, the app doesn't seem to remember/store the passcode, so I have to re-enter the passcode again to access the DB.

The change has been implemented in the new version 2.5.0.0beta12, tell me if it's OK.

[p3yot3]

Yup, that's got it. It now remembers the password when fingerprint is used - great work!

Will test some more......
