Merge lp:~mterry/unity-mir/no-focus into lp:unity-mir

If no app has focus when we get a un-actionable onSessionFocused event, still re-set focus to the shell.

If no app has focus when we get a un-actionable onSessionFocused event, still re-set focus to the shell.

During testing of split greeter, Saviq noticed that the volume up/down buttons didn't work. Some digging discovered that the android input layer thought nothing was focused and that it only happens after maliit-server is running.

Digging into unity-mir, it seems we discard onSessionFocused events that don't relate to an application (like maliit-server was generating). But apparently, android-input is a little confused at that point, and there is code in the function for re-setting the focus for the focused app.

But if no app has focus, we did nothing. In the case where no app has focus, we should also re-set the focus onto the shell. This fixed the volume bug for me.

I disagree. It means discarding the request to focus the new app. The code that follows is just rolling back any side effects of handling the request. I only added a special case to that code anyway, rather than change its meaning.

I could change the comment to "refocusing previous focus" or something like that. But it sounds like a wordier version of the "not doing anything" meaning we already have.

Done.

> "Oo" <- as before please just make empty string
