Hi, I created a simple ionic app using: ionic start myApp blank. I tried to build the app into my android device. I’m getting an error showing- net::ERR_CONNECTION_REFUSED ( http://localhost:8080/ ) This comes after executing a simple app. Can anyone please help?

What is your ionic info output? What device are you testing on?

ionic cli 4.0.2 node- v10.7.0 Device- Samsung- G360H

[image] supra: ionic cli 4.0.2 node- v10.7.0 This is not the output of running ionic info on the console in the project directory. [image] supra: Device- Samsung- G360H That device is 4 years old. Maybe try with a more recent one.

Ok i will try with latest device and will share my experience. Also i will send complete ionic info out put

Make sure you have internet connection when adding the platform and on first run.

If your device is running Android <5, your issue might be similar to this here: [image] Simple Ionic 3 App Not Working on Android Device ionic-v3 Hello dumdem Which android version has your device? I’m having the same problem (and message) while testing on an Android v.4…

For future readers of this topic: If the device you are testing on is using Android 4.x (e.g. Android 4.4 KitKat), this article might explain what is going on and how to fix it: https://ionic.zone/debug/ionic-and-android-4
