How should I handle “No internet connection” with Retrofit on Android

Question

I\'d like to handle situations when there is no internet connection. Usually I\'d run:

ConnectivityManager cm =
    (ConnectivityManager)context.getSystemSer         


        

Answer 1

just do this you will notified even for issues like

UnknownHostException

,

SocketTimeoutException

and others.

 @Override public void onFailure(Call> call, Throwable t) {  
if (t instanceof IOException) {
    Toast.makeText(ErrorHandlingActivity.this, "this is an actual network failure :( inform the user and possibly retry", Toast.LENGTH_SHORT).show();
    // logging probably not necessary
}
else {
    Toast.makeText(ErrorHandlingActivity.this, "conversion issue! big problems :(", Toast.LENGTH_SHORT).show();
    // todo log to some central bug tracking service
} }
