Hi I'm working on an Android App which has the possibility of connecting to a server. This application can work online or offline. For connection to the server, I use AsyncTask, which and in doInBackground is where I do all the network operations. Then I create a new instance of the Asynctask when I click a button. What I would like to know is if there is a way of checking if the server is active in order to launch the AsyncTask. I have thought of try and catch but I would like to know if there is a better solution asked 3 mins ago
