Android Studio + AMD Hyper-V

[rottenkiwi]

Máte niekto kombináciu AMD CPU a Android Studio ?
Ako zapnúť virtualizáciu, aby mi išiel simulátor, keďže mám len Windows 10 Home
a tá Hyper-V nepodporuje ?
Dá sa to aj ináč, ako kúpením Win 10 Pro ?

Bohužel, já mám Intel a Windows 10 Pro.
Co tak použít místo Hyper-V VMware Workstation nebo to udělat ve VMware Player/Fusion?

Workstation stojí ranec, ale Player a Fusion bývaly zadarmo.

Tak zatiaľ to robím na starej i7 + Ubuntu + 8 GB RAM, no ale to tam nesmie nič bežať.
V novej mašine je AMD Ryzen + 16 GB RAM, ale tam AVD nespustím.
A keď sa pokúšam na Ryzene spustiť Ubuntu, tak Kernel Panic.

Ja to na AMDecku nerozjel vubec, jen na Intelu

Keď sa snažím do databázy vložiť riadok, tak mi vypíše toto chybové hlásenie:
Viete mi niekto poradiť, kde mám preklep ?

SQLite nepozna datovy typ number.
A tymto stylom sa s db uz dlho nerobi v androide.
Pouziva sa Room, alebo Realm, kde je to ovela jednoduchsie a staci menej kodu
