Solution

android\app\src\main\AndroidManifest.xml Add internet permission

examble :

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.test">

    <uses-permission android:name="android.permission.INTERNET" /> // add this line

   <application
        android:label="test1"
        android:name="${applicationName}"
