Is there a way to reconnect to Wi-Fi whenever an application accesses the network?
Background: I have a rooted e-book reader that runs Android 2.2 (Sony Reader PRS-T1). The system offers an option to automatically enter Wi-Fi standby mode when the connection is idle, which I like: This behavior saves a lot of battery juice when reading an e-book.
Some of the preinstalled apps know how to reconnect the Wi-Fi whenever they need network access. Unfortunately, conventional Android apps do not know how to do this and fail. For example, I have installed the Kindle for Android app, and it fails to sync reading positions unless I have manually re-enabled the the Wi-Fi before trying to do so.
Is there a method to leave Wi-Fi standby mode and reconnect to Wi-Fi whenever there is demand?
