Why do webviews multiply?

Question

phonegap

Good afternoon, colleagues! I tried to build applications for recording gps tracks on cordova. I wrote a simple code using the cordova-plugin-geolocation plugin, everything seems to be fine, but there was one problem.
I've noticed before in chrome://inspect that an application can run several webviews at the same time, but I didn't pay attention to it. But now when I turn on track recording, if the applications are put in the background (open another), then the recording goes on (data goes to my server), but sometimes if I try to return to the application, for some reason, a new webview opens that does not know anything about the current recording ( which is logical for me to write the flag in window. *). At the same time, in chrome://inspect, I see that my first webview lives on and works, sends data to the server, but I can’t make it active on the phone.
I tested on android, one of these days I will test it on iOS.
The next question is, what is the point of cordova to produce a webview at all? And is there any way to make it work with a single instance? If not, then maybe there are some mechanisms for communication between webviews of one application other than localStorage?
