AndroidRuntime: FATALE AUSNAHME: AsyncTask # 1

Question

Ich habe einen Fehler beim Erstellen meines Codes auf einem Android-Gerät.

Wenn ich auf Start klicke, um die Koordinate zu erhalten, wird die Koordinate auf dem Monitor angezeigt, aber meine Anwendung wurde gestoppt und sendet keine Datenkoordinaten auf meinem Server.

Der Fehlerbericht von Android Studio:

Bitte helfen Sie.

Answer 1

Bitte beachten Sie, dass Ihr URL-Protokoll HTTP und nicht HTTPS ist. Versuchen Sie es mit einem java.net.HttpURLConnection-Objekt oder einer URL "https: // ...".

import javax.net.ssl.HttpsURLConnection;
