Hi all,
In my app I need to update MySql when Back Button is pressed.
Then I detect Back Button and do an update:
The problem is that previous page (that is named homepage) starts with Activity RESUME and then, immediately, starts Activity PAUSE.
Then restart the page where I pressed BACK.
This is the log:
This is the code on Homepage:
From the Log we can see that Main.pulisci=1
PAY ATTENTION: If I cancel from code the query update, all works (I tryed with Jobdone and with wait for... same thing)
Why it happens and how can I solve?
Thanks
Marcom

B4X:

If KeyCode = KeyCodes.KEYCODE_BACK Then

Log(messaggio)
jobx.Initialize("Job2", Me)
jobx.PostString(Main.ServerUrl, Main.Qry)

End Sub
Then restart the page where I pressed BACK.
