Failed to find configured root that contains ...

[UnbreakCode]

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 https://github.com/crazecoder/open_file/issues/94

I used this filepaths.xml:

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

[crazecoder]

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

[UnbreakCode]

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

[MJ12358]

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]

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

[UnbreakCode]

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]

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]

same issue.

[JosephNK]

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]

@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]

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]

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

I completely agree.

[bretbas]

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]

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]

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]

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]

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]

@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.

Same issue

[wuweijian1997]

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"?>

cool.can work

[sherwin]

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]

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>
