Peace of code for network connectivity.
Here is the static method for network related operation like
You can add below static method in your own util class.
Here is the static method for network related operation like
- Check network availability
- Get network information
- Connected to WiFi
- Connected to mobile
- Check connection speed like connectivity is fast, slow or medium
You can add below static method in your own util class.
