Android Question Internet Connection

[Derek Jee]

Hi there

I want to send HTTP requests periodically to upload data to my site. I also want to be able to run this process when connectivity becomes available after a period of no connectivity. Is there some way of running some code based on a change of connectivity without having to have a timer checking for a connection? Or can you suggest an alternative if there is one..

Kind regards..

Derek.

Do you want to send the requests when your app is not in the foreground?

If yes then the I would go for the simplest solution which is to start the process every hour with StartServiceAt and try to send the request.

I want to send them periodically AND when connectivity comes back after a period of no connectivity..

 

[Erel]

The best way to check for connectivity is to try to send a request to the actual server. Therefore I recommend you to try to send a request every few hours.

If you want a "smarter" solution then you can add a static intent filter that will listen to this action: android.net.conn.CONNECTIVITY_CHANGE
See this tutorial: Intent Filters - Intercepting SMS messages in the background

Thank you Erel.. The 'smarter' solution will do another day. Will check for connection with a periodical HTTP request,,

the phone library also has a connectivity change event that you can use.

if you use a service with a timer you can check on IP address aswell, when it is 0.0.0.0 or 127.0.0.1 it's offline too.

on the other hand, there's not really a need to use it when combined to a 1 minute timer or so as the request will just spit out an error that you can catch.

You can utilize this for check WiFi / Mobile connection:

'Chekc Internet connection
'Library for check Connect WiFi
Dim connect_wifi As VBConnect
'Library  for check Connect Mobile
Dim ph As Phone
 
'In this case both ( WiFi / Mobile ) isnt connect
If ph.GetDataState = "DISCONNECTED" And connect_wifi.weconnected = "NO" Then
        Msgbox("MSG", "INTERNET CONNECTION LOST")
        Activity.Finish
Else
        .....
End If
