not a real dev, need help with an app to exit to home screen (or exit another application) on wifi disconnect. [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 11 years ago.

Disclaimer: I h开发者_StackOverflow社区aven't done coding or dev work in a very long time, and never on android.

Running in background mode, my app needs to detect when a particular wifi signal gets lost, and then it needs to return the user to the home screen. Bonus if I can get it to kill a specific application/process as the same time.

Is this possible? If so, any tips or help building it in next 24 hours? Working on rooted motorola xoom, android 3.2.

Thus far I can tell tracking network state via either SUPPLICANT_CONNECTION_CHANGE_ACTION or NetworkInfo.DetailedState DISCONNECTING/DISCONNECTED should be viable options for monitoring the network status. What I haven't been able to yet find is how to get the app (without user action) to then return to home screen and/or exit the currently in use application... I am going to try and build this out tonight. Any help is greatly appreciated!

Use the KISS principle. It's rooted, so install Busybox or create a very simple script with the available tools which can be invoked from init.rc, something along these lines:

while :
do
if ping -c 1 www.google.com
then
   # there's connectivity, do whatever you want
   :
else
   # no connectivity
   # kill the app
   kill the-app-i-want-to-kill
   # return home
   am start -a android.intent.action.MAIN -c android.intent.category.HOME
fi
sleep 30
done

Ahhh, and use the other 15h 45m to find somebody that could do this app correctly.
