Get File Extension on Samsung Android

Question

I want to get the File extension from a Chooser Intent on an Samsung Galaxy S5.

The first returns an empty string and for the second one i get an empty string aswell.

The uri I get from the Chooser intent is

content://com.android.providers.downloads.documents/document/12537

string test = MimeTypeMap.GetFileExtensionFromUrl(uri.ToString()); // empty
string fName = uri.LastPathSegment.Split(new char[] { '\\', ':', '/' }).Last(); // Empty aswell

Try this:

    Uri yourUrl; //your uri
    ContentResolver contentResolver = getContext().getContentResolver();
    String mimeType = contentResolver.getType(yourUrl);
    MimeTypeMap.getSingleton().getExtensionFromMimeType(mimeType);

mimeType is application/something, but this solves my problem somewhat but not completely. Thanks though in advance. – joachim Aug 04 '18 at 12:49

so when you you log the variable mimeType it logs application/"filetype"? – Mr.O Aug 04 '18 at 14:22
Yes but that is still not the Extension – joachim Aug 04 '18 at 14:39
