[Android] SD Card permissions. #332

Lion4K · 2017-12-31T21:13:25Z

Hi, as I believe you devs already know, theres a issue with the SD Storage access on Kit Kat or later android versions.
However I'm here to present a possible solution.

I've seen some apps bypassing this, by using android's internal file picker, and some others have implemented something that makes the app asks the system for SD Card privileges, which in its turn asks the user about it.

This may provide some help.
https://source.android.com/devices/storage/

Again, I'm not a developer, I have little to no knowledge on android developing, the most I know is to use ADB / Fastboot to custom rom procedures, and logcats.
I'm just trying to be helpful.

Happy new year!!

It does not work for native code and it is very slow. Yes, we may wrap filesystem to java, but it is hard task, it will not be compatible with mods, it will be slow and increase memory usage. 0.5s hanging on save,download,changelevel,graph write, reducing connection time 2-3 times because of demoheader. And it may crash/hang because of buggy implementations.
Use "rodir" feature in test versions, it is fast enough and compatible with half-life game code (but not with aghl, xdm, etc...).

mittorn · 2017-12-31T21:39:26Z

P.S you yell about file picker method which does not work, but android 6.0 method with /mnt/runtime may work. I do not have android 6.0+ devices to check if it useful.

Lion4K · 2017-12-31T21:43:56Z

I can test that for you if you want. I can also point to some apps that uses that method that you may be able to take a look at and idk, make sense out of something there, idk jack about that.

a1batross · 2017-12-31T21:56:07Z

It does not depends, request you SD card privileges or not, it will not available from native code.

Rodir is seems to be best solution here.

Lion4K · 2017-12-31T22:06:12Z

Solid Explorer is one of the apps that Uses that. I made a video showing how that happens.
heres the link to it: EDIT wrong video uploaded. please stand by

Lion4K · 2017-12-31T22:06:23Z

BTW whats Rodir? And how to get it?

Lion4K · 2017-12-31T22:07:17Z

Also, how ironic is that, Solid Explorer, a file explorer that relies on android's own file explorer to work. lol;

mittorn · 2017-12-31T22:29:31Z

Does Solid Explorer performing file operations in native code?
If it uses documents api, this method unuseful for xash3d.

Lion4K · 2017-12-31T22:29:47Z

Here's the correct Link:
https://www.youtube.com/watch?v=EP20YbnZBc4

Lion4K · 2017-12-31T22:30:13Z

No I belive it's not native, at least if I understood what native is.

Lion4K · 2017-12-31T22:30:48Z

I mean, I have no idea.

mittorn · 2017-12-31T22:32:23Z

Use /sdcard/xash as game folder, but leave it empty and place game data to /storage/sdcard1/xash and add -rodir /storage/sdcard1/xash to command-line arguments.

mittorn · 2017-12-31T22:35:42Z

Documents API is only availiable in java code. It is different from classic filesystem. It is similar to downloafing files from network Instead of reading.

mittorn · 2017-12-31T22:37:49Z

File managers "uploads" files to sdcard, and does nlt write it directly.

Lion4K · 2017-12-31T22:39:13Z

So "Path to game resources" I set what?

mittorn · 2017-12-31T22:48:17Z

To /sdcard/xash which should be empty. Xash3D will write all changed files there. It will be used as overlay to read-only /storage/sdcard1/xash

Lion4K · 2017-12-31T22:54:47Z

could not found directory valve.

Lion4K · 2017-12-31T22:55:25Z

like, my sdcard path is /storage/F2ED-255F/

Lion4K · 2017-12-31T23:05:56Z

so my Advanced Tab should be:

Command line ar(...)
-dev 3 -log -rodir /storage/F2ED-255F/xash

Path to game resources:
/storage/emulated/0/xash

Pixel format (...)
32Bit

Keyboard does not resizes

Check updates Tick

Update to unstable Untick

enable immersive mode (...) Tick

a1batross · 2018-01-01T08:27:39Z

Forgot to say, it works only on test versions.

Lion4K · 2018-01-02T03:17:05Z

Oh. Where do I get this version?

mittorn · 2018-01-02T08:24:27Z

Lion4K · 2018-01-02T17:33:17Z

Sorry, its probably like, "bitting me at the ankle" but I can't find it. can you please point the link to the apk file?

a1batross · 2018-01-02T18:44:26Z

Read READMR.md file. Use "travis-latest" branch.

Lion4K · 2018-01-02T18:50:23Z

thanks, gonna copy the files one more time, as google play music keeps playing the media files on the game folder.

Lion4K · 2018-01-02T20:47:09Z

works nicely. thanks.

mittorn · 2018-01-03T12:27:54Z

@a1batross
No, just add .nomedia after mediascanner adds files to database

a1batross · 2018-01-03T13:35:21Z

Nope. It's a bug. I don't even think it exist on modern Android. (Yes, I think 4.x branch isn't a modern). 3 янв. 2018 г. 3:27 ПП пользователь "mittorn" <notifications@github.com> написал:

mittorn · 2018-01-03T13:40:04Z

I do not know if ti is bug or feature, but i do not recommend to use it as Samsung devices may have it enabled.

Lion4K · 2018-01-03T16:50:42Z

im using androis 7.1.1, waiting motorola release oreo.

Lion4K · 2018-01-03T16:51:56Z

but yeah the .nomedia file worked like a charm. not only stopped music but also pictures.

Lion4K · 2018-01-03T16:55:31Z

for the mods. lets say i wanna use Crack-Life.
What should I use?
folder name is cracklife.

r/n i'm using:

advanced:

cmd args
-dev 3 -log -rodir /storage/F2ED-255F/xash -game cracklife

Path:
/storage/emulated/0/xash

should I add cracklife to both lines?

nekonomicon · 2018-01-03T17:13:10Z

You must place cracklife folder to xash folder.

Lion4K · 2018-01-03T17:20:05Z

yeah, it is.

all my mods are there

cracklife
clcampaign
cstrike
czero
czeror
valve
ricochet
dmc
etc etc etc

Lion4K · 2018-01-05T02:48:57Z

Would be this one the native thing you were talking about?
It sure does look different from the one I showed on the video.

Lion4K · 2018-01-05T02:50:10Z

It asks directly to the folder and not the whole card.

mittorn · 2018-01-05T07:17:58Z

rewrite xash3d to java and it will work

Lion4K · 2018-01-05T11:09:38Z

When you mean rewrite, isn't it already in Java?
I mean I thought everything in Android was Java, actually Dalvik something idk. I saw something on college but didn't pay attention.

nekonomicon · 2018-01-05T12:45:34Z

Xash3d was written on pure C(menu and game libraries on C++).
Only launchers(black windows) was written on Java.
You can write apps for android on any programming language in combination with Java.
Dalvik - just Google's JVM implementation for android.

Lion4K · 2018-01-05T13:08:42Z

I see, I guess I should had payed more attention to college lol

Lion4K · 2018-01-06T20:11:25Z

Well, about the other mods, I still can't get them to work, how should I fill both lines, like, for example for CrackLife.

cmd args
-dev 3 -log -rodir /storage/F2ED-255F/xash

Path:
/storage/emulated/0/xash

Should I use "-game cracklife" on both of them?

a1batross · 2018-01-06T20:16:14Z

Everything is just like Half-Life, except you need to pass -game cracklife to command line arguments. And also you may have "cracklife" on your " /storage/F2ED-255F/xash"

Lion4K · 2018-01-06T20:51:42Z

but the -game comes after or before -rodir? or it doesn't matter?
because it didn't worked.

I've used exactly like this:

cmd args
-dev 3 -log -rodir /storage/F2ED-255F/xash -game cracklife

Path:
/storage/emulated/0/xash

a1batross · 2018-01-06T21:26:39Z

It doesn't matter at all.

Lion4K · 2018-01-06T21:36:24Z

hm, yeah, it does not work at all.

Lion4K · 2018-01-06T21:38:28Z

BS Launcher doesn't work either.

Lion4K · 2018-01-06T21:40:46Z

Both CrackLife and BlueShift reaches main menu, but does not load any maps. you keep clicking the example "hazard course" and doesn't do anything.

In BS Launcher I used the line -dev 3 -log -rodir /storage/F2ED-255F/xash and it did load the main menu blue background. but still not loading any maps.

a1batross · 2018-01-07T06:19:54Z

Thanks, it seems bug of RoDir. It doesn't adds basedir from rodir before everything.

glad i could help somehow.
