My name is Alejandro Mazuera-Rozo, I am a PhD Student at Universidad de los Andes, and at Università della Svizzera italiana. I am part of a research on the usage of network libraries within android apps. As a result of this we identified that there could be a missing validation of network connection within the project since some network operations are being performed in the application.
As you might know, a device may not be connected to a network. In order to get such information see https://developer.android.com/reference/android/net/ConnectivityManager. Therefore it is recommended for the app to identify whether the device has a network connection available before performing a network operation.
In order to address this issue we recommend you to visit:
Note:public NetworkInfo getActiveNetworkInfo () returns details about the currently active default data network. When connected, this network is the default route for outgoing connections. You should always check NetworkInfo#isConnected() before initiating network traffic, it requires Manifest.permission.ACCESS_NETWORK_STATE
However isConnected() was deprecated in API level 29, one should instead use the ConnectivityManager.NetworkCallback API to learn about connectivity changes, to be more specific the onAvailable() method.
