Android POS (Pax A920) does not allow native/dual debugger.

[mbsy...@gmail.com]

I use Android Studio 3.1 to run a JNI Hello program on Android Phone (Samsung A5) then Native, Dual and Java debugger work normally.

But when I run the same program on Android POS (PAX A920), only the java debugger is working normally, but Native/Dual debugger does not work and I get error as follows. How to resolve this problem?
