No physical button input when launching from other frontends on android #485

I hope this is the right repo. Sorry if it aint.. I'm having an issue with Parallel-n64. Whenever I launch this particular core from a frontend different from retroarch. I sometimes don't have have input.

Expected behavior
core launched from command runs the game with buttons working

Actual behavior
core launched from command core runs the game without buttons working. Not even retroarch overlay's and such can be opened.

Steps to reproduce:
Launch an instance of parallel using the following config::

-n com.retroarch.aarch64/com.retroarch.browser.retroactivity.RetroActivityFuture
-e ROM {file.path}
-e LIBRETRO /data/data/com.retroarch.aarch64/cores/parallel_n64_libretro_android.so
-e CONFIGFILE /storage/emulated/0/Android/data/com.retroarch.aarch64/files/retroarch.cfg
-e IME com.android.inputmethod.latin/.LatinIME\n  -e DATADIR /data/data/com.retroarch.aarch64
-e APK /data/app/com.retroarch.aarch64-1/base.apk
-e SDCARD /storage/emulated/0
-e EXTERNAL /storage/emulated/0/Android/data/com.retroarch.aarch64/files
--activity-clear-task
--activity-clear-top

CANNOT reproduce this on the following device
OS: Google Pixel 3A with Xbox controller. works perfectly there..

Start by reproducing the launch through RetroActivityFuture with the provided Android configuration and affected ROMs, comparing it with a direct RetroArch launch. Investigate the parallel_n64_libretro_android.so entry point and the frontend-provided input path. Done means physical buttons and the RetroArch overlay work reliably across the listed frontends and affected games.
