I'm not familiar with the software you're using (on the server side), but if the WebView is going to be invisible, why are you using it? Does the triggering web page/API use some Javascript or something to accomplish the task? If not, I would use a different method. Forgive me, it's been a while since I've done any active coding on Android, but I'm pretty sure there are HTTPConnection classes or something to that effect that take a Url object (or string) that can make the requests much more efficiently if all you need to do is send and receive some data.

    Hello,

    I wrote an (really basic) application to control access for a
    building. This application exists of multiple buttons (10 in total).
    Per door there are 2 buttons. One button acts as an pulse buton.
    When clicking the pulse button a timer function will be enabled
    and after 5 seconds the function will be disabled.
    The other button enables or disables the function manualy (without
    a timer).

    When the function is enabled a URL request is send out to load
    within a WebView. The URL that is requested is an URL trigger for
    a webrelay which will trgger the door to unlock.
    When the function is disabled a URL request is send out to load
    within a WebView. The URL that is requested is an URL trigger for
    a webrelay which will trgger the door to lock.
    For testing the URL request i used URL's like:
    http://www.cisco.com
    http://www, nu.nl <http://nu.nl>

    The URL's requested will appear in a Webview (which will be
    invisible in the final version).
    Each door has it's own door WebView.

    So for short:
    One door has:
    2 buttons;
    1 timer function;
    1 WebView.

    There are 5 doors in total.

    Now the problem coms that after running this error will occure:
    A/libc: Fatal signal 11 (SIGSEGV) at 0x0000001c (code=1), thread
    25881 (WebViewCoreThre)

    After searching on the internet, i learned this could be a memory
    issue.
    But i don't have a clue to how address this, or what the problem
    could be. I tried to eleminate the images that i used, but that
    didn't work.

    The application is develloped for Android 4.1 (Jellybean).

    How can i resolve this problem ??

    Regards.

    Dennie
