I'd like to get the full file path, from a URI. The URI isn't a Image, but it's a music file, but if i do it like the MediaStore Solution, it won't work if the app user selects eg Astro as browser, instead of Music Player. How do I solve this?

The PathUtil method will be only working in below oreo and if it is oreo than it is likely to crash because in oreo we will not get the id but the entire path in data.getData() so all u need to do is create a file from uri and get its path from getPath() and split it.below is the working code:-
Uri uri = data.getData();
File file = new File(uri.getPath());//create path from uri
final String[] split = file.getPath().split(":");//split the path.
filePath = split[1];//assign it to a string(your choice).
The above code will work in oreo and if it is below oreo than PathUtil will work.Thanks!
String filePath=PathUtil.getPath(context,yourURI);

one of the answers that exist on the current page (this), is correct but it has some mistakes. for example, it won't work on devices with API 29+. I'll update the above code and post its new version. I think this post should be marked as the final answer.
Updated code: (Added WhatsApp support)

But now according to the android latest guideline, you could not direct access getExternalStorageDirectory(). You need to implement a workaround for this

Try this.
public String getRealPathFromURI(Uri contentUri)
{
String[] proj = { MediaStore.Audio.Media.DATA };
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}

You can use get File path from diffrent SDk versions
Use RealPathUtils for it
public class RealPathUtils {

String wholeID = DocumentsContract.getDocumentId(uri);
// Split at colon, use second item in the array
String id = wholeID.split(":")[1];
String[] column = { MediaStore.Images.Media.DATA };
// where id is equal to
String sel = MediaStore.Images.Media._ID + "=?";
Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
column, sel, new String[]{ id }, null);
int columnIndex = cursor.getColumnIndex(column[0]);
if (cursor.moveToFirst()) {
filePath = cursor.getString(columnIndex);
}
cursor.close();
return filePath;
}

For Kotlin:
Just create a new file with name URIPathHelper.kt. Then copy and paste the following Utility class in your file. It covers all scenarios and works perfectly for all Android versions. Its explanation will be discussed later.

After that, you can call this method passing context and uri objects
FileUtils.getReadablePathFromUri(context,uri)

I prefer using Simple Storage:
// For document file
val documentFile = DocumentFileCompat.fromUri(context, uri)
val path = documentFile.absolutePath // e.g. /storage/emulated/0/Music/Torisetsu.mp3
// For media file
val mediaFile = MediaFile(context, uri)
val path = mediaFile.absolutePath // e.g. /storage/emulated/0/Music/My Love.mp3
To check whether the URI is media file or document file, use isMediaDocument extension function:
val isMediaFile = uri.isMediaDocument

val selection: String?

if (uri.path!!.contains("/document/image:")) {
databaseUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI
selection = "_id=?"
selectionArgs = arrayOf(DocumentsContract.getDocumentId(uri).split(":")[1])
} else {
databaseUri = uri
selection = null
selectionArgs = null
}
try {
val column = "_data"
val projection = arrayOf(column)
val cursor = context.contentResolver.query(
databaseUri,
projection,
selection,
selectionArgs,
null
)
cursor?.let {
if (it.moveToFirst()) {
val columnIndex = cursor.getColumnIndexOrThrow(column)
realPath = cursor.getString(columnIndex)
}
cursor.close()
}
} catch (e: Exception) {
Log.i("GetFileUri Exception:", e.message ?: "")

val path = if (realPath.isNotEmpty()) realPath else {

I had a hard time trying to figure this out on Xamarin. From the suggestions above I came up with this solution.
private string getRealPathFromURI(Android.Net.Uri contentUri)
{
string filename = "";
string thepath = "";
Android.Net.Uri filePathUri;
ICursor cursor = this.ContentResolver.Query(contentUri, null, null, null, null);
if (cursor.MoveToFirst())
{
int column_index = cursor.GetColumnIndex(MediaStore.Images.Media.InterfaceConsts.Data);//Instead of "MediaStore.Images.Media.DATA" can be used "_data"
filePathUri = Android.Net.Uri.Parse(cursor.GetString(column_index));
filename = filePathUri.LastPathSegment;
thepath = filePathUri.Path;
}
return thepath;
}
