Imagine you’re somebody reading your post with no other information. What sorts of questions would you ask? What sort of advice could you give? What else would you want to know?

@rapropos when i logged in my app in devide then

net::ERR_CLEARTEXT_NOT_PERMITTED

this type error show

That error indicates that you are trying to make a HTTP request instead of HTTPS

I have answered this in stackoverflow before, please have a look
https://stackoverflow.com/questions/56261777/i-get-err-cleartext-not-permitted-while-running-on-my-mobile-but-it-is-running/56261901#56261901

In production environment, you might want to have https instead of http.

And by the way, the title is not reflecting the problem I guess.
