Hier möchte ich eine Android-Downcount-App für das nächste Fußballspiel, das Datum aus dem Internet und zeigt die verbleibende Zeit, um das Spiel zu starten. Nach einigen Recherchen habe ich den folgenden Code, aber es zählt nur Datum, nämlich JJJJ-MM-TT, aber ich möchte es Datum und Uhrzeit zählen (JJJJ-MM-TT-Std: Min).Machen Sie einen Android-Countdown
