Runtime Exception beim Ausführen von Cordova App

Question

Ich habe ein Problem mit Cordova Anwendung sowohl auf Emulator und einem Android-Gerät ausgeführt. Es ist eine App mit Phonegap-Vorlage-Reagieren-Hot-Loader-Vorlage erstellt.

Hier ist ein adb log:

Answer 1

Das Problem war, dass NPM-Skripte aus der Vorlage Config geändert. xml und geändert <content src="index.html" /> bis <content src="http://10.0.2.2:8080" /> so Android Gerät/Emulator wurde nicht mit der Datei index.html serviert.
