Back button on Android quit application about fries

[jaunesarmiento]

Hi there @aboudard, no I believe this is not "normal". What version of Fries are you using?

[aboudard]

I use 1.0.0 according to the readme, I juste downloded the master.
I tried just now to catch the backbutton with phonegap, but with no success, I try harder :D

[jaunesarmiento]

Alright. Can you try doing a console.log() inside the code where you try to catch the back button? I'm very willing to help you with your problem. :)

[aboudard]

I am right now :)
I can't load any console at all on new-contact.html ...

Added this in the bottom of the page (works perfect in index.html)

<script src="js/cordova-2.7.0.js"></script>
<script>
    window.addEventListener('load', init, false);
    function ready(e){
        console.log("Loaded");
        document.addEventListener("backbutton", onBackKeyDown, false);
    }

    function onBackKeyDown() {
        window.history.go(-1);
        console.log("Back");
    }

    function onError(error) {
        console.error(JSON.stringify(error));
    }

    function init(e){
        document.addEventListener('deviceready', ready, false);
        console.log("Init Loaded");
    }
</script>

But will the app still exit if you press the back button on index.html?

Edit: I currently don't have an Android phone right now that's why I'm asking. xD

[aboudard]

Well, it seem like there is really a problem with the back button, when I have activated multiple tabs, it looks like application is freezing, and sometimes I see the pages with no style at all ... pretty bad ... I try to see if this behavior is caused by the webview component, I'll install Fries on a http server to be sure.

[jaunesarmiento]

Hmm. That's odd. Is there any particular reason why you're catching the back button functionality? Cause when I tested this, I never had to catch the back button and still it works fine.

By the way, the style on other pages does not load if stack.js fails to load properly in index.html.

[aboudard]

Yes, that's very strange. here is what I did :

• I see that pressing back button on the device makes me go out of application even when I am on new-contact.html for example.
• I think "hey let's see what phonegap says in the backbutton event"
• I plug phonegap.js, set the listener (in new-contact.html)
• no luck, absolutely no javascript is loaded, native or phonegap event ... none
• I plug phonegap.js and listeners in index.html > events work just fine
  ...
  I keep on :)

@aboudard I just tested your code for the back button issue on a phonegap project with Fries, the problem is non existent. In addition to that I highly doubt that the problem is stemming from stack.js , I suggest trying on the side a new Phonegap project without Fries and implement dynamic page loading (which is similar to how Stack.js does) and test the app on the same device.

[aboudard]

Well there is no "code of mine" to test, my simple test was to install both on a device and an emulator a simple Android / Phonegap app with fries demo pages.
I will try to work on a brand new project like you say, thanks for the advice.

[aboudard]

Ok, I made a new Phonegap app with phonegap build, starting from both sample project from Fries and Phonegap-start, and the problem doesn't happen !

My first phonegap project (with the bug) was built with the Android dedicated ant command line "create" ... I will try to reproduce, that might be a good advice ... not using this build ... :|
that would be more relevant than saying "non existent" ;)

[jaunesarmiento]

Thanks @aymanfarhat. I couldn't test the problem.

@aboudard you could also try to build and install https://github.com/jaunesarmiento/HelloFries on your device. That project was made using ./create <project_folder_path> <package_name> <project_name> command from the Cordova Android distribution.

Back button seems to be working fine on v2.0.0
