Android Question Error with fingerprint manager - hardware detected

AHilberink · Apr 10, 2019

Hi,

I got an error on using fingerprint_manager on a Samsung TabA with v8.1.0 android.

fingerprintmanager_gethardwaredetected (java line: 112)
java.lang.RuntimeException: Object should first be initialized (JavaObject).
at anywheresoftware.b4a.AbsObjectWrapper.getObject(AbsObjectWrapper.java:50)
at anywheresoftware.b4j.object.JavaObject.getCurrentClass(JavaObject.java:258)
at anywheresoftware.b4j.object.JavaObject.RunMethod(JavaObject.java:118)

It is the same I found in:
https://www.b4x.com/android/forum/t...rint-manager-hardware-detected.97650/#content

This was v4.4.2 of Android.
The solution works also for me, but can I do this also on my v8.1.0?

Best regards,
André

It is safe to change the code to:

B4X:

Public Sub getHardwareDetected As Boolean
   Return sensor.IsInitialized AND sensor.RunMethod("isHardwareDetected", Null)
End Sub

I will update the class code.
