I have a self developed app for Android and I need your help:
The App has to detect the "online status" of a (internal) webiste (IP), which is for circa 20 seconds online after pushing a button on the website. It is irrelevant, how long the smartphone stays before the button-push occurs in standby mode. It has to be RELIABLE!
In non-standby-mode, that phone detects every online status of the website correctly, but it ignores it in the "non-standby"mode (after pushing ON/off-Button of the phone -> black screen).
I think it is a small help for a experienced android developer.
