Root filesystem unavailable when root permissions granted. about simple-file-manager HOT 63 CLOSED

Hey, can you shoot me a mail at [email protected] , so I can send you a test version please? It works fine on my device :p

from simple-file-manager.

I also can confirm that after granting root privileges there's nothing in the root folder.

from simple-file-manager.

@tibbi any idea on this bug?

from simple-file-manager.

the guy reported this issue right after releasing it, his problem was that "awk" package was missing and I couldnt use the required command. I guess that will be your issue too. Root folders could be listed without that too, but its currently not a high enough priority to rewrite it.

from simple-file-manager.

That's weird because I have busybox installed and:

# adb shell
X1_Max:/ $ su
X1_Max:/ # echo $PATH
/su/bin:/sbin:/vendor/bin:/system/sbin:/system/bin:/su/xbin:/system/xbin
X1_Max:/ # which awk
/su/xbin/awk

Should I install it in some other place?

from simple-file-manager.

Aha, can you then try this version Im attaching? You will probably see some messages appear as you select the root folder while having Root Access enabled in app settings, whats written on them? Uninstall the current one and allow installing apps from unknown sources at the security settings of your device. Remove the ".zip" appendix from the attachment, its just because github doesnt allow uploading .apk files. Thanks
app-release.apk.zip

from simple-file-manager.

I did what you asked for, but it looks like there's no messages when I select the root folder. I have root access enabled and removed the previous version of the app.

from simple-file-manager.

how about this one? Also what if you disable Root Access, do you see any files there?
app-release.apk.zip

from simple-file-manager.

When I start the app, now I can see this message (with root):

check: simple mobile tools

Still no root content. What is the "simple mobile tools"?

from simple-file-manager.

its just a simple echo to see if the console works at all, and I see the output. How about now? What do you see?
app-release.apk.zip

from simple-file-manager.

Now it says:

path:

from simple-file-manager.

Alright, this should do something more then. It apparently somehow got to trimming the slash of the root folder, which is not happening on my device.
app-release.apk.zip

from simple-file-manager.

Now it's

path:/

from simple-file-manager.

and nothing else after it? No files or other messages appear?

from simple-file-manager.

No other message, no files.

from simple-file-manager.

ok, here is hopefully a last one
app-release.apk.zip

from simple-file-manager.

It's still the same message and no files.

from simple-file-manager.

weird... Ill try a simple "ls", do you see anything?
app-release.apk.zip

from simple-file-manager.

Wow, now it worked :D

from simple-file-manager.

can you send me some screenshot? Maybe the values are in a different order than on my device, so it parses it wrong.

from simple-file-manager.

I think it's not what it supposed to be. But at least it displays something :)

from simple-file-manager.

tomorrow I will compare it with the output on my device and figure out whats wrong. Thanks for now

from simple-file-manager.

Ok. :)

from simple-file-manager.

So, how about this one? Ive changed something. You shouldnt see any popups, it should just work in theory.
app-release.apk.zip

from simple-file-manager.

I've just tested it, and still no files.

from simple-file-manager.

oh cmon, how about this one? The first message will be "index ", is the number 4 or 5? What about the next messages, can you give me a screenshot of one again? Thanks
app-release.apk.zip

from simple-file-manager.

Index 5

from simple-file-manager.

How about this? It should print out a weird command.
app-release.apk.zip

from simple-file-manager.

from simple-file-manager.

You should see some "Output xxx" messages now, do you? Do you maybe see some "RETURN xxx" or "ERROR xxx"?
app-release.apk.zip

from simple-file-manager.

No messages this time.

from simple-file-manager.

wow, how about now?
app-release.apk.zip

from simple-file-manager.

Now it says:
Completed 0

from simple-file-manager.

ok Ill try removing parts of that command, hope it wont last much longer. Do some messages appear now?
app-release.apk.zip

from simple-file-manager.

No messages.

from simple-file-manager.

now?
app-release.apk.zip

from simple-file-manager.

Still nothing.

from simple-file-manager.

this?
app-release.apk.zip

from simple-file-manager.

Yes, now I have something.

from simple-file-manager.

the file/folder permissions? letters like d/r/w/x/- ?

from simple-file-manager.

Yes:

from simple-file-manager.

now?
app-release.apk.zip

from simple-file-manager.

No messages.

from simple-file-manager.

I dont know man, looks like there is something wrong with the system command inside awk. Its strange that it doesnt even give some error, I dont know how to fix it without having a broken device. Ill give up now as it apparently doesnt affect anyone else, but thanks a lot for the testing and feedback.

from simple-file-manager.

Maybe it's because of Android 7.0?

from simple-file-manager.

Im not sure. There just arent enough people using the file manager yet, especially with root access. I will have a rooted xiaomi where I want to install Android 7, I just have to wait 2 more days before they allow unlocking it...

from simple-file-manager.

Ok, so if you had something to test, just ask. :)

from simple-file-manager.

you could test Amaze File Manager at https://play.google.com/store/apps/details?id=com.amaze.filemanager , or its at f-droid too. Its an opensource file manager, it has root access hidden somewhere inside settings too. Ive checked their code already, but it looks weird. I might have to rewrite my way of handling root folders too so it wont use awk at all. The File manager just isnt a priority for now tho, there are more popular apps too.

from simple-file-manager.

I've just checked it, and its root feature works fine. BTW: it's a really nice app :)

from simple-file-manager.

ok thanks. Guess you can use it if you need root :D

from simple-file-manager.

Root handling will be rewritten in 3.2.0, check if is better. You still cannot really do any operations, just hopefully browse the items.

from simple-file-manager.

I just checked and I don't have good news. When I grant root permissions and select the "root" storage, the app thinks a few seconds and then crashes.

from simple-file-manager.

Ok, I see your crashdump, it shouldnt be anything difficult. Just to know for sure whats wrong, can you try this version? It shouldnt crash, can you send me the message that will appear? Thanks
file-manager-release.apk.zip

from simple-file-manager.

Here's the message:

from simple-file-manager.

alright cool, thanks. Can you try this, if it works? You wont see any error messages in case it goes wrong. Try browsing between folders etc.
file-manager-release.apk.zip

from simple-file-manager.

It looks like it's working now (at least I get the file list), but files have 0-byte size.
I got 1 crash while switching the dirs.
And also switching dirs takes a really long time, and sometimes the app hangs.

from simple-file-manager.

ok thats good enough, I will be improving it over time step by step :) I will update the playstore version in a couple days, i dont want to update it too frequently. Get version 3.2.1 from playstore whenever it gets available so you wont miss the updates. Thanks

from simple-file-manager.

Ive just released 3.2.1, it should fix that crash

from simple-file-manager.

I had that crash only once, and I wasn't able to reproduce the issue after that.

I just checked whether changing dirs works without a problem, and it does, but it's a little bit slow -- I wasn't able to enter a dir that has 100+ files in it, but there was no crash, so I think it's good. :D

from simple-file-manager.

alright. Ye it will be improving over time, step by step :) Root file handling is done in a whole different way than normal files so I basically have to implement everything from scratch.

from simple-file-manager.

Hello, I am encountering a different but probably related issue with v3.3.2 running on Android 5.1.1.
Please see the attached screenshot.

from simple-file-manager.

heh, ye Ill take a look at it someday, thanks

from simple-file-manager.

some rooting related things changed since then, open a new clean issue if some reproducible issues still happen
