Application.OpenURL() alternative for Android API level > 23

Hello fellow developers, I need your help.

I used to be able to open PDFs through my Unity App with the command:

Application.OpenURL(filepath/filename.pdf);
But now I can't use it anymore and in the Unity documentation it says to use the FileProvider.

For me it has been an unmitigated disaster. I am not able to get it to work.
As soon as I try and modify the Android.manifest, the app crashes as soon as it opens.

Code (CSharp):

1. <provider
2.     android:name="android.support.v4.content.FileProvider"
3.     android:authorities="${applicationId}.fileprovider"
4.     android:exported="false"
5.     android:grantUriPermissions="true">
6.     <meta-data
7.         android:name="android.support.FILE_PROVIDER_PATHS"
8.         android:resource="@xml/file_paths" />
9. </provider>

Just putting this inside the <application> </application> makes it crash.
I also put in the 'file_paths.xml' in Assets/Plugins/Android/res/xml/ folder.
Even without the meta-data, it just crashes.

The worst part is, even if I was able to make it work so it doesn't crash, I don't know which command I could use in Unity to make it open the PDF.

What should I use instead of Application.OpenURL()??
Thank you for your time. Any help is very much appreciated.

 

I'm trying to do the exact same thing. I'd love to hear if anyone has a solution.

 

I think I've stopped the application from crashing on open. It's working on the Android emulator at least. The trick was to copy AppData\Local\Android\Sdk\extras\android\m2repository\com\android\support\support-v4\24.1.1\support-v4-24.1.1.aar to my Unity project's folder Assets/Plugins/Android. That's annoying. Shouldn't resources like this have been detected and bundled automatically? It's outline here on stackoverflow: https://stackoverflow.com/questions...e-content-fileprovider-classnotfoundexception
