Hello and Merry Christmas everyone,

I'm trying to run a QML and Android test application using Qt 5.7 but got stuck with this issue that is coming up every time i try to run:

SDK, NDK settings under Qt Creator seems to be all good:

All smooth under Android Studio, as well.

Already tried downgrading sdk-tools to 25.2.5 based on a stackoverflow answer, but to no avail.

If anyone had the same problem i would really appreciate if you could give me some guidance.

Sorry!
Just a silly issue solved based on the logs: installed openjdk-8-jdk.
All ok!
