There are still two things I'm not sure how it'll work:

1. mesa provides libgbm. How would OBS know whether it needs to Prefer mesa
libgbm or Renesas libgbm?
2. how do you ensure Renesas libEGL a) provides the same so version and b)
that specific
RPM gets installed in the image instead of mesa-libEGL

Re: [IVI] [Tizen Application-dev] how to back to previous page

[VanCutsem, Geoffroy]

Hi Bray,

There is no such mechanism in Tizen that I'm aware of. That's due to the fact 
there is no restrictions on what the UI should look like (as such it's up to 
the UI designer to decide whether having a back button, hard or soft, is even 
desirable).

Thanks,
Geoffroy

Hi,

Thank you for your reply.

In andriod,the system back key pressed,the running app will back to previous 
page. (app does not do any operation for the back )
Does TIZEN IVI have the same mechanism?

Hi Bray,

There is no official native API in Tizen 3.0. It's possible of course to use 
the core APIs of the various middleware components but I would advice to 
architect it carefully so as to work nicely within the Tizen architecture (esp. 
regarding multi-seat/multi-user and the security framework).

Having said that, if you can give some more details on what APIs you intend to 
use there may be folks on this mailing list that could help with your question 
regarding a 'back' button.

Hi everyone:

I'm developing a native app on Tizen IVI 3.0.

When I press the back button,I want to back to previous page.
Is there any API I can use or I must memory the flow history?
any examples can be  send to me.

thanks!
