In `@app/src/main/java/app/gamenative/ui/model/MainViewModel.kt`:
- Line 601: Update launchAppWithArgs and the MainUiEvent.LaunchApp handling so
each launch request carries its own appId and execArgs, rather than relying on
shared state.execArgs read later by PluviaMain when creating XServerScreen;
preserve the existing launch behavior while preventing overlapping requests from
overwriting one another.
In `@app/src/main/java/app/gamenative/ui/screen/xserver/XServerScreen.kt`:
- Line 3977: Update the drive-remapping logic around finalExecArgs so
replacements match complete host-path prefixes only, preserving boundaries such
as requiring a path separator or end of string after the matched path. Order the
available drive mappings from longest host path to shortest before applying
them, ensuring nested paths use the most-specific mapping.
- Line 3984: Update the command-to-argv handling around
ProcessHelper.splitCommand() and finalExecArgs to strip grouping quote
delimiters from parsed arguments before passing them to ProcessBuilder or
Runtime.exec(String[]), while preserving spaces within quoted paths.
In `@app/src/main/java/app/gamenative/utils/IntentLaunchManager.kt`:
- Line 84: Update the executable matching logic around executablePath to
normalize and compare basenames, allowing an exe value such as pico8.exe to
match paths like Games/pico8.exe, while preserving exact-path matching when the
caller supplies a full executable path. Retain case-insensitive comparison
behavior.
- Line 60: Update the URI parsing logic in IntentLaunchManager to read the
documented EXTRA_EXEC_ARGS parameter first, while retaining the existing
execArgs query name only as a backward-compatible fallback if it was previously
published.
- Around line 59-66: Validate external execArgs values in IntentLaunchManager
for both the Uri.getQueryParameter("execArgs") path and the EXTRA_EXEC_ARGS
path, rejecting the launch request when either contains a NUL character before
returning LaunchRequest. Preserve the existing argument normalization for valid
values and ensure invalid requests do not proceed to XServerScreen or
GuestProgramLauncherComponent.

Preserve drive-path boundaries during remapping.
replace(drive[1], "${drive[0]}:") also replaces path prefixes. For example, a mapping for /storage/emulated/0/ROMs converts /storage/emulated/0/ROMs2/cart.p8 into B:2/cart.p8. Nested mappings can also select the first mapping instead of the most-specific mapping.
Match complete path prefixes only, and apply mappings from longest host path to shortest.

I think it is okay. It is not like somebody is going to pass dozens of overlapping paths in execArgs.

@lennyomg, understood. The current implementation is acceptable for the expected execArgs inputs. No change is required in this pull request.

Description
Added new parameters to the intent launch.
exe- find a container to launch by exe name, expico8.exeexec_args- override existing exec args, ex-run "/storage/emulated/0/ROMs/pico8/pico dino.png"The existing
app_idparameter works fine withexec_argstoo.This feature was implemented specifically for Pico-8 to enable starting cartridges from ES-DE or other launchers, but it should also work with other applications.
ES-DE integration example:
Paths are translated automatically; however, you should first add an extra drive and map it to the folder containing your files. For example:
B:->/storage/emulated/0/ROMs//storage/emulated/0/ROMs/pico8/pico dino.pngbecomesB:\pico dino.pngRecording
run2.mp4

Adds two optional intent extras so external launchers can start a specific executable with custom arguments.
New Features
exeresolves the target container by executable name, so launchers can launch games without knowingapp_id.exec_argsoverrides the container's default exec args and translates Android paths using configured drive mappings.app_idflow and withgamenative://URIs.exec_argsare unescaped before the command is built.exec_argskeeps the container's existing exec args unchanged.Written for commit db106e3. Summary will update on new commits.
