The problem with the last version of Da player is when you add a URL, then close the app (kill from recents), then open the app again, the list is empty, and it gives you the dialog popup to enter new url again. Strangely enogh, if you add at this point a local file (m3u for example, it adds the file, and the url that was gone appears again from nowhere => we end up with 2 items in the list, previously 0). Hope that helps (tested on Android P btw)
