Flutter-permission-handler: FileSystemException: Cannot open file....(OS Error: Permission denied, errno = 13)

[prasantco]

I cannot select image from gallery. This is my logcat
FileSystemException: Cannot open file, path = '/storage/emulated/0/DCIM/s9camera/Pic_2020_06_04_19_36_15.jpg' (OS Error: Permission denied, errno = 13).
I'm using permission_handler package for handle permission. Storage and Access Media Location permission has already granted by user but the issue is generated every time when pick image or video from external storage. Inside manifest file we have added android:requestLegacyExternalStorage="true"
Suddenly i get issue on the production app , please support us

This is a file system permission issue, not a user consent permission issue (which is what the permission_handler is trying to solve). Please also have a look at issue #145, #190 and #275.

[prasantco]

I had already gone through issue #145, #190 and #275 but the issue is genearting also,

[mvanbeusekom]

Like I said, this is not something related to the permission_handler but to the file system and is not something I am familiar with.

[prasantco]

Can you suggest to us how we can resolve this issue as soon as possible?
because it's a product app issue.

The only thing I can think of is to check if the correct permissions are in the AndroidManifest.xml file:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.xxx.yyy">
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
...
</manifest>

Otherwise I would try and have a look at the phone it self maybe, check if it is the hardware (maybe SD card is protected, formatting error, ...).

I'm finding the issue please upgrade your library with Android 29.
Upgrade
compileSdkVersion 28 to compileSdkVersion 29 in build file
targetSdkVersion 28 to targetSdkVersion 29 (It's optional) in build file
android:requestLegacyExternalStorage="true" in Manifest file

How is this related to the library? This should be set in your Application right?

I mean I can update the Example app, but this is simply the example and should not effect your application. Please correct me if I am wrong.

The build.gradle part of the Android library code is set to compileSdkVersion 29 (see here)

[prasantco]

Add
android:requestLegacyExternalStorage="true" in Manifest file

@visual-velocity there is not AndroidManifest.xml file, this belongs to your App so there is nothing I can do on the library side. You will need to add it yourself, just like you need to add the <uses-permission /> tags to your AndroidManifest.xml.

Again I can add it to the example app, but it is just an "example" app which will not affect your application.

[prasantco]

I'm so sorry Please ignore my last message or comment. Thank you for your
support. It's really appreciated.
