Android wifi background check

Question

I started about a month or two, and I need to develop an internal hosting system based on Wifi fingerprint. I need an application that periodically scans the Wi-Fi AP and sends the result data to the server.

So far, I have created an application that allows you to scan a Wi-Fi AP and get results when it detects different connections. I am doing this in the main action using a broadcast receiver. The application can also send data to the server.

Now I want to transfer this process to a batch process in the background, even when the smartphone is in sleep mode.

I already read several topics on how to do this, but none of them was clear. My question is the best way to do this? Using a service / IntentService with a timer / timer?

Thank.

Edit: Thank you! AlarmManager and services are working fine!

Answer 1

I think that AlarmManagersuits your needs, use setRepeatingto set something, to repeat every time X

Schedule a repeating signal. Note: for synchronization operations (ticks, timeouts, etc.), it is easier and more efficient to use Handler. If an alarm is already set for the same IntentSender, it will be canceled first.
