问题
I am using Qt 5.13 with Qt Creator 4.9.2. I can successfully build the Debug version of my application for Android, but when I try to compile the Release version I get:
16:57:35: The process "/opt/Qt/5.13.0/android_armv7/bin/androiddeployqt" exited with code 15. Error while building/deploying project Notizie2 (kit: Android for armeabi-v7a (Clang Qt 5.13.0 for Android ARMv7)) When executing step "Build Android APK"
I am not even sure where to begin to fix this, there are no errors other than this in the compilation log. This are the ending output of the comilation log:
