For those like me who need a custom domain. You need to change the host file of the device to point to
197.168.1.101 backend.test
** 197.168.1.101 api.backend.test**
With:
adb pull /system/etc/hosts /myfolder
Edit the file
adb remount
adb push /myfolder/hosts /system/etc/hosts
As for the ionic build…
ionic cordova platform rm android
cordova platform rm android
ionic cordova platform add android
