[ANDROID] "intent:" protocol to call with arguments retroarch on URL link

Tested with :

• RetroArch: 1.8.9 downloaded on official Google Store ( Play Store )
• OS: Android 9 Pie on non-rooted phone

Hi all,

After reading lots of topics about RetroArch and Intent protocol, I find the following (old ?) command-line :

am start --user 0
  -n com.retroarch/.browser.retroactivity.RetroActivityFuture
  -e ROM /storage/emulated/0/Download/megamindtris.bin
  -e LIBRETRO /data/user/0/com.retroarch/cores/genesisplusgx_libretro_android.so
  -e CONFIGFILE /storage/emulated/0/Android/data/com.retroarch/files/retroarch.cfg
  -e IME com.android.inputmethod.latin/.LatinIME
  -e DATADIR /data/user/0/com.retroarch
  -e APK /data/app/com.retroarch-1/base.apk
  -e SDCARD /storage/emulated/0
  -e EXTERNAL /storage/emulated/0/Android/data/com.retroarch/files
  --activity-clear-top

My Goal : Have the ability to call with arguments RetroArch with "intent": protocol on a URL Link of a HTML / PHP page without rooting a phone in the aim to keep for instance the warranty of the phone .

I tried that for instance but it doesn't work :

<a href="intent:#Intent;component=com.retroarch/com.retroarch.browser.retroactivity.RetroActivityFuture;S.ROM=/storage/emulated/0/Download/$YourFileName;S.LIBRETRO=/data/user/0/com.retroarch/cores/genesisplusgx_libretro_android.so;S.CONFIGFILE=/storage/emulated/0/Android/data/com.retroarch/files/retroarch.cfg;S.IME=com.android.inputmethod.latin/.LatinIME;S.DATADIR=/data/user/0/com.retroarch;S.APK=/data/app/com.retroarch-1/base.apk;S.SDCARD=com.android.inputmethod.latin/.LatinIME;S.EXTERNAL=/data/user/0/com.retroarch;end;">Click Me!</a>

Note : $YourFileName = Name of the file

Do you have solutions / ressources in the aim to understand how to do please?

Thanks in advance,
Jackobo

Start by comparing the listed am start command and the intent: URL targeting RetroActivityFuture, using the stated RetroArch 1.8.9 and Android 9 setup. Done would mean identifying a documented, non-rooted URL invocation that launches RetroArch and passes the ROM and other arguments; the issue provides no repository file or test to begin with.
