Is it possible to default the screen to Portrait mode?

[Lewis Z.]

I have Android developement board and it doesn't have screen rotation
feature. When it boots up, it always show landscape. Is it possible to
default the screen to Portrait mode?

I do have all the BSP source code and I can flash all the images.

Thanks a lot!

I believe it defaults to whatever the native orientation of your screen is.  If you want it to start out rotated, you will need to change PhoneWindowManager to implement the policy you want.

The screen rotation default value is consistent with the framebuffer
mode.
If fb mode is landscape, android show UI with landscape.

Thanks.

Dianne & Xinyu, thank you for replies.

But where can I this framebuffer mode parameter so I can modify it?

It's whatever your driver reports the screen size to be.  Sorry I can't help you more than that, I don't know anything about your driver.

Hi,I met the same problem,
now I could change the launcher by chaing manifest.xml:
android:screenOrientation="portrait"
But I could not change the rotation of screen lock.

Change the code in the lock screen -- it is down in frameworks/policies/base/phone/...  The orientation here is set in the code, not in a manifest (the lock screen is not an activity).
