i found this error after i build to apk
with this https://ionicframework.com/docs/intro/deploying/

#4

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

#5
cli packages: (C:\Users\UserID\AppData\Roaming\npm\node_modules)

    @ionic/cli-plugin-proxy : 1.5.8
    @ionic/cli-utils        : 1.19.2
    ionic (Ionic CLI)       : 3.20.0

global packages:

    cordova (Cordova CLI) : 8.0.0

local packages:

    @ionic/app-scripts : 3.1.11
    Cordova Platforms  : android 7.0.0
    Ionic Framework    : ionic-angular 3.9.2

System:

    Node : v8.9.3
    npm  : 5.5.1
    OS   : Windows 7

I tried it with an Android device

#6

Of course you did, you posted a screenshot from an Android device.

But what device model and which Android version is installed on it?

#7

my android version is 5.1.1
but I also tried with the Android 6 version the same problem

#8

Ok. Try these two things:

Your Cordova tooling seems to be out of date, which might be causing all kinds of problems.
You can read about how to figure out the current Cordova versions and how to update CLI, platforms and plugins here: https://ionic.zone/cordova/update

And create a new app with ionic start and see if it all works there.
