Player checking in Android via pm list packages

[Rem01Gaming]

Is your feature request related to a problem? Please describe.
There is a way to check players in Android, we can retrieve package list from command pm list packages and then check if MPV or VLC is installed.

Describe the solution you'd like
Example of checking installed player in Android:

if pm list packages | grep is.xyz.mpv >/dev/null; then
	echo "MPV Android installed"
fi

if pm list packages | grep org.videolan.vlc >/dev/null; then
	echo "VLC Android installed"
fi

Additional context
Instead of completely disabling the player checking on Android, this is much more better solution.

You think I haven't tried that? I know that it won't work.

[Rem01Gaming]

Hmm try /system/bin/pm list packages

[CoolnsX]

Interesting, it works now, earlier it used to not work. The same binary path u mentioned.

I have Android 14 btw

I have Android 14 btw

Android 14 is a bit weird on some case like this
In case it still failing, we can disables the player checking only if the pm command returns an error.

[CoolnsX]

Ye, the first pm is from termux. And this one is from system.

Ye, the first pm is from termux. And this one is from system.

It's actually the same pm from system, just how to call it that diff

[CoolnsX]

That calling via termux's pm is not working properly.

[Rem01Gaming]

Ye

@CoolnsX wanna do sth with this or should we omit this?

[CoolnsX]

We need more devices to confirm this, we can implement it but it should not be blocking

@CoolnsX I think you're right, after some research Google have been restrict QUERY_ALL_PACKAGES permission access since Android 11.
I'm also found this discussion on termux packages repo which talking about the same thing, however somehow pm list packages working some ROMs (yes it's not device dependent). About why it was working on some ROMs is either device maintainer or ROM developer have been bypassed or skipped this particular security changes.

Since this was working on some ROMs, I recommend to disables the player checking only if the pm command returns an error.

androidPlayerCheck() {
	package_list="$(/system/bin/pm list packages)"

	if echo "$package_list" | grep -q Failure; then
		echo "Checking of players is disabled due to selinux restriction"
		return 1
	fi

	if echo "$package_list" | grep -q is.xyz.mpv; then
		echo "MPV Android installed"
		return 0
	fi

	if echo "$package_list" | grep -q org.videolan.vlc; then
		echo "VLC Android installed"
		return 0
	fi
}
androidPlayerCheck

But yeah we probably need to think twice to implement this, it's up to you.

I think the reason why /system/bin/pm list packages doesnt work is because of SELinux related stuff. It depends on kernel or SELinux status and rules

It really only works if there is a workaround to get around the SELinux restriction, or by setting the SELinux to Permissive (which is a security flaw that is not recommended to do, and requires root)
