So on a phone it will be trickier, but possible. The general idea is that you install RetroArch, then in it install DOSBox-Pure, then you install Win98 and then you install AoE2. All this can be done on Android phone. I can guide you through the details if you would really be interested.

On laptop it becomes much easier. E.g. just follow https://aoe2.arkanosis.net/linux/
