Network Security Configuration for Android platform

Create a DisplayObjects/platforms/Android/res/xml/network_security_config.xml file:

<? xml version= "1.0" encoding= "utf-8"?>
< network-security-config>
  < base-config cleartextTrafficPermitted= "true">
   < trust-anchors>
    < certificates src= "system" />
    < certificates src= "user" />
   </ trust-anchors>
 </ base-config>
</ network-security-config>

Edit DisplayObjects/platforms/Android/config.xml as:

< platform name= "android">
...
< resource-file src= "www/res/xml/network_security_config.xml" target= "app/src/main/res/xml/network_security_config.xml" /> 
 < edit-config xmlns:android= "http://schemas.android.com/apk/res/android" file= "app/src/main/AndroidManifest.xml" mode= "merge" target= "/manifest/application"> 
< application android:networkSecurityConfig= "@xml/network_security_config" /> 
 </ edit-config> 
</ platform>
