I was using httpclient module in ionic_V3 when I try to migrate to ionic_V4. The Httpclient is working fine in browser (ionic serve). When I build the app the Httpclient is not working in real device. Kindly suggest me what changes I should do" ?
It isn’t an
Httpclientissue as far as I feel. It’s mostly the URLs (as in APIs) you hit that are not accessible.
To get the error logs, you need to connect to an emulator or a device(enabling USB debugging). Once you have any of these in place, launch the app and open chrome browser’s console(click 3 dots on top right) “More tools => Remote devices => Your device name => Inspect”.
Now, you should see the messages on Chrome console itself.
I just installed the apk in marshmallow its working fine. But not working only on Pie version mobiles.
Found the solution.
I was building app on Pie version (ANDROID - 9).
On the code I changed the HTTP to HTTPS (For secured communication)
Android has introduced App Transfer Security (ATS) like in Apple IOS 9. Android also introduced ATS.
Which means from version - 9 Pie we should use HTTPS (secured connection).
That solved my problem.
Thanks for the reply
