Android ITrustManager.isDeviceLocked(int)'on a null object reference

[ChristopherAN]

Hello,

I am trying to make an Android application with new version of QT.
NDK used : 20
Java JDK 8
Qt Creator 4.10.1
Qt 5.13.1
Android SDK 28

Compilation went fine but I faced a problem when launching on the device, the app force quit with this exception:

java.lang.NullPointerException: Attempt to invoke interface method 'boolean android.app.trust.ITrustManager.isDeviceLocked(int)' on a null object reference

Strange thing is that I had no problem launching same project compiled with Qt 5.11

I'd try NDK 19 (for me NDK 20 didn't work with Qt 5.12.3)

I just tried with NDK 19 or SDK 29 always same problem.
Even QT Example project didn't work, they compile but don't launch with same exception.
