I had thought that the MainActivity class would BE the

This is my isConnected() method: if(!checkNetwork(parent)){ return false; } if(!checkConnection(url)){ return false; } return true; Now, I check the connection by just using if(isConnected()) but I'm getting the exception. So what I need to do is move the above method into an
