Can you include a logcat with console enabled set?

That doesn't look good:

Andrea, is this an IPC issue?  The error message in the logcat seems to come code you added to make DataStore certified-only in bug 942639.

Comment 8

[Andrea Marchesini [:baku]]

yep. it seems so. I'm debugging it.

Comment 9

[Andrea Marchesini [:baku]]

Part of the problem was related to bug 962516. Now this is landed on m-c.
The app still has a wrong behaviour. I'll continue to investigate it.

Comment 10

[Peter Dolanjski [:pdol]]

Is this critical to fix for 1.3?  Will it affect multiple apps?

To my understanding, this was originally marked as a blocker since this impacts a target preinstalled partner app. Since it's a gecko bug, this can potentially impact multiple apps if they happen to trigger the same workflow that this app does. baku could provide a tech perspective on this if need be.

The issue was in part related to bug 962516. With that patch landed, I don't see this issue. But I'm still debugging it to be 100% this issue is fix.

If someone wants to help to debug it, would be nice if you can reproduce this issue or something else. Thanks.

Can we get ETA to fix this bug? Thank you.

Comment 14

[Andrea Marchesini [:baku]]

The index.html of this app creates an <iframe mozbrowser> point to this URL: http://vds.vivo.com.br/ This URL, returns a WAP page. Unsupported by B2G. I guess the problem is in the app itself.
Could it be that they are expecting a different user-agent? Can we ask info to the author of this app?

Comment 15

[Andrew Overholt [:overholt]]

Maria, do you have any contacts at Vivo that can help with this?

I think Diego can help us here, setting ni for him

[Jason Smith [:jsmith]]

Wait a second - before we assume this is TE, I'd like to know why this works fine on 1.1.

Can we an explanation of the behavior on 1.1 on a Buri device?

Comment 18

[Beatriz Rodríguez [:brg]]

Jose Enrique or Simon, Could you please in parallel check this issue with the app developer?

It seems a user-agent detector problem. When I use ffos 1.1 user agent I get an HTML page:

curl -L http://vds.vivo.com.br/  -i -A "Mozilla/5.0 (Mobile; rv:18.1) Gecko/18.1 Firefox/18.1"

but with 1.3/1.4 (and desktop too) I see a WAP page:

curl -L http://vds.vivo.com.br/  -i -A "Mozilla/5.0 (Mobile; rv:29.0) Gecko/29.0 Firefox/29.0"

Ah ha. It's a UA issue. Thanks for the help - that makes this is a TE issue. Switching to the TE product & removing the blocking flag.

(Agreed with José Enrique that he is taking this over to Vivo who are developers of the app)

Comment 22

[joseenrique.alvarezfernandez]

Notified to Vivo the bug. They are working on it

Comment 23

[joseenrique.alvarezfernandez]

This was solved time ago. Nevertheless I've checked it out and works for me

Mass closing on Tech Evangelism::Preinstalled B2G App as Firefox OS is no longer a thing.
