I encountered this issue, too. The short answer is that the version of the game engine Adastra uses is old enough (circa 2018) that recent versions of Android and Android devices don't support the files it builds.
The long answer is that recent versions of Android require developers to target new versions of the Android SDK for security permissions purposes. Also, recent Android devices are 64-bit using the ARM v8 instruction set. I think the Adastra 17 APK targets an SDK for Android 5 or 6 and is building for 32-bit ARM v7.
I had to use the Windows zip version of Adastra with Ren'Py's 8.2 SDK to recompile the code and build a new Android APK targeting a much newer version of the Android SDK. I have no idea if it's 100% compatible where it's moving from RenPy 6.99 to 8.2.1 and thus Python from 2 to 3, but playing through the recompiled APK, I didn't encounter any crashes or significant jank, so it seemed reasonable enough as a stopgap.
