android ChooserActivity ContentProvider Permissions Denial

[olokobayusuf]

Hey @teleportal-andrew, can you try exporting the Unity project to a Gradle project instead of building an APK directly from Unity? If you inspect the generated Android manifest, that will show whether Unity might not be adding the <provider> tag to the final manifest.

however I haven't been able to track down the class name to provide for android:name

Here's what I see in the merged android manifest:

        <provider
            android:name="androidx.core.content.FileProvider"
            android:authorities="my.app.uri.natshare"
            android:exported="false"
            android:grantUriPermissions="true" >
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/filepaths" />
        </provider>

Though it seems here androidx.core.content.FileProvider is used as the "class name" that I was trying to track down above

It may be worth noting that the share chooser is able to share the file - this error message is specifically related to being able to preview the file from the chooser

I spent some time trying different modifications - setting android:readPermissions on the provider, using grantUriPermission(...) from addMedia explicitly, adding FLAG_GRANT_READ_URI_PERMISSION to Intent chooser directly after Intent.createChooser(...) all without results

as far as I can tell from the documentation, provider in manifest file and chooser codebase look correct
Android Version is 11 build number RP1A.201005.004

my only (crude) guess at the moment is that file preview comes from a separate app bundle that also needs permissions granted

This is critical info then. Looks like the issue is that the preview image doesn't show up? If so, it's probably some quirk with Android. Issues like these are pretty difficult to debug, because there's poor documentation on how it is expected to behave.

I believe this is internal to Android. I'm closing this issue.
