I still have the same problem: ionic serve work fine, even uploading the app on ionic view works fine, but when I build the app and put it on the Play Store, I get no internetā€¦ I tried all the solution above, but nothing worked so far.

Change your code at project\resources\android\xml like above

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

Hey guys,

Iā€™m developing an application with Ionic/Angular as frontend and Java Spring boot as backend.

When theyā€™re both running om my laptop the communication between them works perfectly. Currently iā€™m trying with the APK (both debug and signed) on my mobile phone, but it cannot make any calls to my backend. I have tried all the above suggestions but with no success.

Whitelist plugin is added, permissions are set, access-origins (*) is set and allow-navigation (set to wildcard). Am I missing something?

Thanks in advance!

Are you missing HTTPS?

I had similar symptoms, changing my API from HTTP to HTTPS solved it right away.

From Android 9 Pie and up, all requests need to have encryption. The SO answer below shows how to get around it if you need http.

kkraus, thank you so much. I would have wasted even more days looking for the cause of the problem.

I think it also depends on the Android version. The missing intermediate cert didnā€™t cause a problem on my phone with Android 8. But on another phone with Android 10 it failed.

I could confirm with https://www.ssllabs.com/ssltest/ , that the intermediate cert was missing on the server. In my case it is an IIS7.5. Steps to install the missing certs are described here: https://www.xolphin.com/support/IIS/IIS_-_Install_root_and_intermediate_certificates
