Rotation on Android

[joel.epsteinBUS31vi]

Hi all -

I'm fairly new to Android development and could use a quick pointer.

I'm building an app in which almost all the cards need to be portrait, but a couple need to be in landscape.
In iOS, in my "on OpenCard" script, I put either mobileSetAllowedOrientations "portrait" or mobileSetAllowedOrientations "landscape left"
This works great, and the orientation of the app flips just like I want when I navigate from screen to screen.

However, under Android, things aren't working like that at all.
In fact, I'm actually quite puzzled by how it's working.
Seems like if I rotate the device right when I'm on a portrait orientation screen, the app will rotate to the right and shrink to fit the screen. But then it seems to be locked in that orientation until I force quit the app.
And it seems as if the app does nothing whenever I rotate the screen in any direction whenever I'm on a screen that has the "landscape left" orientation set.

I'm sure that I'm probably missing something fairly basic, but I'm not sure what it is.

I'd appreciate any advice you might be able to provide.

Thanks so much.

Hi Joel,
Do you use accelerated rendering? Try turning it off and see if that helps.

Some Android devices don't follow the rules, my Kindle Fire reverses landscape right/left
I have to use "the machine" to lock it in one mode if it's a Fire.

Work arounds.. all over the place.

Thanks, again, Simon.

I'm not using accelerated rendering.

What's confusing me is that on the Android (Galaxy 5 & Nexus 7) when the
mobileSetAllowedOrientations "portrait"
is set for a card, and I rotate the device into a landscape orientation, the app does indeed rotate - when, in fact, it shouldn't. And what's worse, it seems to get stuck that way.

Surely I'm doing something wrong here. Can't quite figure it out though.

Any ideas?

OK...
Try moving ...AllowedOrientations to preOpenCard
If not there then on closeCard from the previous card.
Or maybe a combo of both.

Yes, I am just guessing, I do not know specifically why it isn't working.

Code: Select all

on orientationChanged
   answer mobileDeviceOrientation()
end orientationChanged

Maybe that will give you a clue as to what the device thinks.

Fantastic. Thanks for those tips. I've got to head to bed - but I'll check it out in the morning...

Hi all -

I believe there may be a bug with rotation on Android devices. I've attached a sample.

RotTest.livecode.zip

(63.4 KiB) Downloaded 369 times

I'm using LiveCode 7.0

if I have the following code in a preOpenCard script of one card:

Code: Select all

   if the environment is "mobile" then
      mobileSetAllowedOrientations "portrait"
   end if

and then this code in the preOpenCard script of another:

Code: Select all

   if the environment is "mobile" then
      mobileSetAllowedOrientations "landscape left"
   end if

on iOS devices, the screen will appropriately rotate as I navigate between the two screens.

However, on Android, I do not see this behavior.

Furthermore, on Android, when I have that code and I'm on the initial card, I actually can rotate the device and the orientation of the card will change (which it should not). Even more strange is the fact that if I do not include that script, and rotate the device, then the orientation of the card does not change.

Perhaps I'm missing something, but it seems like a bug to me.

Can anyone confirm? And if this is indeed a bug, can you please remind me how to submit?

Thanks so much.

Hi Joel,
Yep, tested on my Kindle and it does as you say, but... only when I changed cd 2 to landscape right. Landscape left nothing happened and it all just stayed in portrait mode.

It works in 6.6.1.

Thanks for checking, Simon. I appreciate your ongoing support.

And thanks, Andy. I appreciate you pointing this out to me. I'll definitely check it out.
