I have noticed that there is no props for the StatusBar component (React Native) to include an icon or logo of any kind as in this documentation: https://facebook.github.io/rea
There are 2 kinds of icons in Android status bar.
One kind is system icons that come from framework-res.apk and extracted to the /system/framework , you can't change those without having some elevated privileges on the device and mounting the system image read/write.
The other kind is the notification icons as mentioned here before. For iOS you can't really change much.
Your screenshot shows both kinds and you want to put your icon next to the Network bars icon but those are system icons (on Android)
Here is a plugin that deals with notifications (and notification icons) both platforms and wraps everything, easy to use with react You can find a sample native code for iOS notification here and Android here:
