Cordova-plugin-ionic-webview: Android 4.4.2 connection refused

[odecharette]

Hi,

I try to run my ionic app on a android mobile having Android 4.4.2
When I run the app (ionic cordova run android) I have "ERR_CONNECTION_REFUSED"

I have seen this article https://ionic.zone/debug/ionic-and-android-4
But I also read that the last version of [email protected] is supposed to give back support for Android kitkat

Could you confirm and help me ?

Thanks

Then it's not the exact same problem as you say the error connection message is fixed but the OP is about it not being fixed.
Create a separate issue about what doesn't work properly.

I'm sorry, you're right. My real problem was that Android 4.4 KitKat do not support the JavaScript Promise functions.
