将屏幕方向锁定为仅一种风景和一种肖像模式

Question

Let's say my app has two activities A and B . And, also, let's call the posible screen orientations landscape-1 , portrait-2 , landscape-3 and portrait-4 .
I would like to lock the orientation of A to landscape ( 1 and 3 ), and B to both landscape and portrait ( 1 , 2 , 3 and 4 ). So, to do this, I used sensorLandscape . Later I realized that sensorLandscape is for API 9 or greater, and I want to support older versions. I searched for a way to emulate sensorLandscape behaviour, but I didn't find anything. So I'm now going for a simpler approach: I would like to use landscape mode on activity A (this is, just 1 ), but I don't want the user to be able to use landscape-3 on activity B (so there's no weird turning when going back to activity A ).
To sum up , the idea is the following:
Posible screen orientations for activity A : landscape-1 .
Posible screen orientations for activity B : landscape-1 and portrait-3 .
Any ideas on how to accomplish this behaviour?

Answer 1

Use it and don't support api <13 just because no need to make extra work

Done is better than perfect

Don't worry you are still targeting 97% of Android Users with Api >=9.
