A few questions about WiFi states: I am starting this service from an component which is invoked periodically by the AlarmService. This service attempts to connect to a remote server and fetch the data. Assuming that a device goes to sleep and Wifi connection is dropped, how should I code my remote connection setup and data transfer calls? Will the device still try to connect via WiFi, timeout and then try to connect via GPRS or whatever? What checks should I be doing? Should I listen to WiFi state changes and use it somehow? Presently, I have wrapped the remote connection call with a predicate that checks the Network State. If the device is not connected to the network(via any medium), an attempt is not made to connect to the remote server. If the official documentation details on this or If you've written about it somewhere please share and oblige me.
