Depois que eu seleciono o emulador e dou "ok", aparece aparecem as seguintes mensagens:
19:39 Emulator: [12988]:ERROR:android/android-emu/android/qt/qt_setup.cpp:28:Qt library not found at C:\Users\Pierre\AppData\Local\Android\Sdk\emulator\lib64\qt\lib
19:39 Emulator: Could not launch 'C:\Users\Pierre\AppData\Local\Android\Sdk\emulator/qemu/windows-x86_64/qemu-system-i386.exe': No such file or directory
19:39 Emulator: Process finished with exit code 2
Já criei outro emulador e não solucionou o problema.
