There's a piece of software called Waydroid[1] that allows you to run Android applications on GNU/Linux platforms - including the PinePhone. Sxmo, despite its name, can run Wayland instead of X and therefore supports Waydroid.
Personally, I haven't managed to get Waydroid to work, a task hindered due to some massive initial downloads which are required to set it up. However, I haven't tried particularly hard, and there are videos online by those more successful than me[2].
