I would like to maintain a central list of the battery status of my devices. For my Linux laptops, I will write a small shell script that reads the battery information from the kernel and uploads it to my webserver.
I have no idea how to do this for Android devices, though. Basically I would like them to open
http://example.com/tracker.php?id=cell&battery=0.67 every 30 minutes or so.
Is there an app that can do that? Although I have never programmed on Android yet, I have experience with Java and Linux. Is it possible to program something like that with reasonable effort?
