Network Type may not be being verified

[caev03]

Dear Developer!

My name is Camilo Escobar, I am a PhD Student at Universidad de los Andes, Colombia. I am part of a research on the usage of network libraries within android apps. As a result of this we identified that there is a missing validation of network type within a method since some network operations are being performed in it. As you might know, a device can have various types of network connections. For the full list of possible network types, see https://developer.android.com/reference/android/net/ConnectivityManager. Therefore it is recommended for the app to identify the type of network available before performing a network operation.

Note: Wi-Fi is typically faster. Also, mobile data is often metered, which can get expensive. A common strategy for apps is to only fetch large data if a Wi-Fi network is available.
