Android Question BiometricManager failing after restart App

[Markos]

Hi All,

Something very peculiar happened today I launched my App like on many occassion and used the BiometricManager module however when I restarted the App the Biometric.show does not display. I reverted to the FngerPrintManager and it works flawlessly

What I realise is if I wait a 30 to 60secs it works again whereas FingerPrintManager does not need that delay to work in quick succession, can we investigate that delay if it can be reduced? if not truly required.

Possibly some library/function in memory is blocking until it is closed completely.

Are you using B4XPages?

Nothing is retained when you restart the app, assuming that the process was actually killed and restarted.

No using the standard b4a. template

Correct app was properly exited by swiping off the screen unless there is some temporary hold in memory for the BiometricManager, about 10 to 20 secs, I only noticed because I had some testing that required to kill and restart quicklly otherwise I would never have noticed this difference in readiness between this and FIngerPrintManager

You should switch to B4XPages. It will fix many lifecycle related issues.

I know I would have to eventually, you know the old dog new tricks kinda thing. , Next App I will use to adapt to that framework
