Failed to find configured root that contains ... #255

UnbreakCode · 2023-06-15T15:14:08Z

used version: 3.3.2
flutter version: 3.10.4
anodrid 12

I cannot open my image with open_file. The app has permission (permission_handler) and I added everything to Manifest.xml.
The interesting thing is that I define a different path to the file than specified in the exception. I'm using '/data/user/0/xxx/images/1.jpg'

Seems to be the same issue as #94

I used this filepaths.xml:

<?xml version="1.0" encoding="utf-8"?> <resources> <external-path name="external_storage_directory" path="." /> </resources>

The text was updated successfully, but these errors were encountered:

crazecoder · 2023-06-16T01:40:51Z

Make sure this file is app private directory, then determine whether public directory, if not, you need to usePermission.manageExternalStorage.request()

UnbreakCode · 2023-06-16T07:00:15Z

Make sure this file is app private directory, then determine whether public directory, if not, you need to usePermission.manageExternalStorage.request()

I already did this before opening the file with this path now: /data/user/0/com.example.app/1.jpg

MJ12358 · 2023-06-17T03:27:51Z

I'm also having this issue.

The requested directory looks like this:

/data/user/0/com.example.app/app_flutter/files/my_folder/my_file.jpg

I am using path_provider getApplicationDocumentsDirectory to achieve this.

But when using OpenFile, it attempts a directory that looks like this:

/data/data/com.example.app/app_flutter/files/my_folder/my_file.jpg

Is this correct or are we missing something here?

Here is the filepath.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <external-path name="external_storage_directory"
    path="." />
  <external-path name="files"
    path="Android/data/com.example.app/" />
</resources>

Here is the stacktrace:

OpenFile: 3.3.2
Flutter: 3.10.4
Tested on Android 8.1

crazecoder · 2023-06-20T06:52:26Z

I tried it in the example, and it didn't report an error, it just couldn't find the file

UnbreakCode · 2023-06-20T09:12:24Z

I tried it in the example, and it didn't report an error, it just couldn't find the file

but the file is definitely there, I checked it via device explorer

MJ12358 · 2023-06-24T03:45:05Z

I've put together a simple test app to recreate this issue.
We are creating files within our app's directory, yet OpenFile does not work, permissions aside it continues to fail via:
PlatformException(error, Failed to find configured root that contains...).

Tested on Android 7 and 8.1

JosephNK · 2023-06-24T15:55:24Z

same issue.

JosephNK · 2023-06-24T16:37:28Z

I don't know why, but when I add the code as below, it works fine.

Hope you can help me in any way.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <root-path name="root" path="."/> <-- added
    <external-files-path name="external_storage_directory" path="." />
</resources>

MJ12358 · 2023-06-26T00:11:53Z

@JosephNK This works...
But I'm concerned with the implications of this.
I thought the "root-path" tag allows access to any file or directory within the device's file system.
What does this mean for permissions?

Edit: looks like using "READ_EXTERNAL_STORAGE" is all that is necessary for this tag.
Edit2: just uploaded an app to Google with "root-path" set and they don't seem to care, so maybe I won't either...

I'm more interested in using "files-path", which should represent the internal storage area specific to your app.
In this scenario, "root-path" and "external-files-path" shouldn't even be necessary, correct?
This way external storage permissions wouldn't be required.

UnbreakCode · 2023-06-29T09:40:50Z

Edit2: just uploaded an app to Google with "root-path" set and they don't seem to care, so maybe I won't either...

sometimes they do due to security reasons. But this is still not the real solution for this issue.

EDIT: this fix does not work for me

MJ12358 · 2023-07-02T20:34:44Z

But this is still not the real solution for this issue.

I completely agree.

bretbas · 2023-07-05T20:05:03Z

The same:
PlatformException(error, Failed to find configured root that contains /data/data/com.example.farm/app_flutter/ProtocolFileCache/52b62d73-2053-4e67-8a95-8522eb915e88.docx, null, java.lang.IllegalArgumentException: Failed to find configured root that contains /data/data/com.example.farm/app_flutter/ProtocolFileCache/52b62d73-2053-4e67-8a95-8522eb915e88.docx

but file was:
/data/user/0/com.example.farm/app_flutter/ProtocolFileCache/93eaffaf-6635-4e67-87b5-fb807f7deba2.docx

MJ12358 · 2023-07-06T02:33:49Z

This is definitely an issue when using internal directories like this:

getApplicationDocumentsDirectory aka /data/user/0/com.example.app/app_flutter
vs:
getExternalStorageDirectory aka /storage/emulated/0/Android/data/com.example.app/files

When using "OpenFile", the former produces the directory of: /data/data/... (which is incorrect).
The latter will correctly open the file.

This issue stems from this line FileProvider.getUriForFile (OpenFilePlugin.java:170).

There must be some association between the "FileProvider" and the resources/paths within "filepaths.xml" that is not working.

MJ12358 · 2023-07-06T22:30:25Z

Configuring filepaths.xml with the following works for me when opening files via getApplicationDocumentsDirectory:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
  <files-path name="files-path"
    path="../" />
</paths>

The important bit is path="../".

I think what is happening is that "files-path" assumes a directory of /data/user/0/com.example.app/files and what we really need is /data/user/0/com.example.app/app_flutter.
Therefore we back out of the "files" directory and into our app's root directory.

However, this still seems to require "READ_EXTERNAL_STORAGE". Is this correct?

Exactly, but this requirement is acutally not really needed because it's an app internal storage while runtime

praveenverma720 · 2024-02-06T12:03:36Z

Just replace your fileprovider.xml or any name you have set for file-provider.xml code with below code

<?xml version="1.0" encoding="utf-8"?>

<paths xmlns:android="http://schemas.android.com/apk/res/android">

  <files-path name="files-path"

    path="../" />

</paths>

mzeqirii · 2024-02-14T18:36:20Z

This is a question and not a solution. It seems like this is the solution to the problem. However what I don't understand it, where to find the fileprovider.xml in my project. Any help would be appreciated.

<?xml version="1.0" encoding="utf-8"?>

<paths xmlns:android="http://schemas.android.com/apk/res/android">

  <files-path name="files-path"

    path="../" />

</paths>

MJ12358 · 2024-02-15T00:45:16Z

@praveenverma720 If you look at the previous two comments directly above yours, you will see that this has already been suggested.
You have not provided any new information.
If you have novel information on the permissions issues mentioned above please report. Thanks.

@mzeqirii The location for this file is: android/app/src/main/res/xml. This information is in the readme of this repository.

cool.can work

sherwin · 2024-04-28T08:30:44Z

I use this configured in working. android\app\src\main\res\xml\filepaths.xml

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
  <files-path name="files-path"
    path="../" />
</paths>

And , Save file use await getTemporaryDirectory(); .
Open file example

OpenFile.open('/data/user/0/com.xxxx.android/cache/image.png');

I can also help you.

tanvir-robin · 2024-06-29T15:26:06Z

Replacing the filepath.xml with this finally worked for me.

<?xml version="1.0" encoding="utf-8"?> <paths xmlns:android="http://schemas.android.com/apk/res/android"> <files-path name="files-path" path="../" /> </paths>
