Hi there i have convert angular 17 project into android app by using capacitor, and i want that app can connect to my local iis server which will be in same network. i have made provision to set iis server IP address on login page as SetURL button, but still app not connecting to iis server. but when i tried same connection from mobile chrome browser it got connected …please help me out for this issue.

i have make changes in capacitor.config.ts file as follows.

server:{
hostname: ‘com.example.app’,
allowNavigation:[‘*’],
cleartext:true,
}

You need to explain some more what you are trying to do. Are you making API calls to this IIS server?

3

Yes…i have deployed dotnet core API on iis and im trying to access it through angular application. it works when i;m calling those api through angular app (chrome browser), but as soon as i convert that application into apk file that application is not able to connect…

4

Is the API endpoint HTTP or HTTPS? By default, Android blocks HTTP requests.

5

Ok…its HTTP only…let me check with https…

6

If you have to use HTTP, you can create an exception using network_security_config.xml. See Unable to carryout HTTP post on Android - #2 by twestrick

7

I have tried by changing HTTPS but still…android app not connecting.

8

Have you checked for errors? You can use DevTools by going to chrome://inspect/#devices in Chrome. Also check LogCat in Android Studio. It could be a CORS issue.

Hey …This is the logCat i’m getting after sending request to iis through apk,

This is the xml file ‘network-security-config’

<?xml version="1.0" encoding="utf-8"?> localhost com.example.app

what we can do next…

No idea what you are trying to say here but appears you didn’t follow Unable to carryout HTTP post on Android - #2 by twestrick

Your network_security_config.xml should look like this:

<?xml version="1.0" encoding="utf-8" ?>
<network-security-config>
   <domain-config cleartextTrafficPermitted="true">
        <domain>192.168.0.100</domain>
   </domain-config>
</network-security-config>

Then make sure that config file is registered in your AndroidManifest.xml file.

Hi sorry if i missed any thing in reply…now below i’m sharing all the files related to this issue.

This is the - network-security-config

<domain-config cleartextTrafficPermitted="true">
  <domain includeSubdomains="true">localhost</domain>
  <domain includeSubdomains="true">192.168.0.100</domain>
</domain-config>

I have mension into android.menifeast.xml file
android:networkSecurityConfig=“@xml/network_security_config”

but still apk file not able to connect to iis server.

12

Not sure. You could try setting server -> androidScheme to http in your Capacitor config just to see if that works.

Hurrey… :grin: , it works and now i can connect to iis through apk app. thanks a lot for you valuable time and support. Thanks…twestrick
