Android gets the current type of mobile phone network (2g, 3g, 4g, WiFi) and mobile phone model, version number code _android

Get mobile phone Model: Android.os.Build.MODEL

Get the phone's SDK version number: Android.os.Build.VERSION.SDK

Get the phone's current network type code as follows: This is a tool class that you can save for later use.

}

The above is a small series to introduce Android to get the current type of mobile phone network (2g, 3g, 4g, WiFi), as well as the phone model, version number of all the description, I hope to help you!
