Ich versuche, Benutzerregistrierungsformular in Android mit dem aktuellen Standort zu übermitteln. Ich bin neu in der Android- und Java-Entwicklung. Wenn ich versuche, auf myLat und myLan der Methode onLocationChanged in meinem Name-Wert-Paar-Code zuzugreifen, kann sie beide Variablen nicht finden. Wie kann ich auf beide Variablen in meinem Name-Wert-Paar-Code zugreifen?
