I am connecting to a remote server in my Android application. I have noticed that when the device goes to sleep/standby WiFi is disconnected and that when the device wakes up, it gets reconnected. A check-Network-Connectivity code has been put before httpClient.execute(..) call.
An assumption is made that when the data transfer is being done and if the device goes to sleep then Android runtime will switch to another medium for connectivity(3G,GPRS etc.). I have a few questions regarding the same: 1. How seamless is the switch from WiFi to alternate cellular service say 3G? Does the developer have to do anything at his end? 2. Sometimes, WiFi are preferred over other channels. Is it possible to wait for WiFi to reconnect? Links to APIs and/or some sample code would be great. 3. Should I make the thread to explicitly hold a wakelock before it performs a network IO? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
