Android 11 : pdf document throw com.android.providers.media.documents throw NullpointerException

When i select a pdf document, the content uri is

content://com.android.providers.media.documents/document/document%3A30

Logcat logs :

D/[FilePath plugin]:: File - Authority: com.android.providers.media.documents, Fragment: null, Port: -1, Query: null, Scheme: content, Host: com.android.providers.media.documents, Segments: [document, document:30]

FilePath.getPath is looking for a media document

       // MediaProvider
        else if (isMediaDocument(uri)) {

The docId is document:30, type is "document"

But doesn't handle "document"

           Uri contentUri = null;
            if ("image".equals(type)) {
                contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
            } else if ("video".equals(type)) {
                contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
            } else if ("audio".equals(type)) {
                contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
            }

=> contenUri is Null

Start with FilePath.getPath and the MediaProvider branch shown in the issue, using the Android 11 content URI and logcat output as the reproduction. Trace how the document type is handled and verify that selecting a PDF no longer produces a null content URI or NullPointerException.
