Question

Android - Orientation Change - exits app but w/o crashing

Answer 1

A:

Did you try to add android:configChanges="orientation" to your activity declaration in the manifest? Normally when the configuration changes, the activity is shut down and restarted. Adding this "flag" prevents this and calls the onConfigurationChanged() method instead.

Thanks. Yes, I tried it several times, including placing it in each activity tag. And, as mentioned, also tried using the sensor tag. That's what's so odd about it. The configChanges has always seemed to work in my other app's. The only other odd thing about what I see from the logCat is the duplicate finish request in the warning.

Added: I locked in the portrait orientation, ran the app in landscape then, toggled to portrait and noticed that just before the app exited, the layout displayed. This almost suggest is is related to the duplicate finish cited in the logcat. My code, however only calls finish in the different activities, not in onCreate. Puzzling...

Answer 2

+2 A:

If you use the above code, make one modification:

android:configChanges="keyboard|keyboardHidden|orientation"

using only "orientation" will handle orientation changes driven by accelerometers and such, but on devices with a physical keyboard and a slide-out screen the activity will still be shut down and restarted any time a user slides open their keyboard.

Thanks! That sort of did the trick! It stopped it from dying but, it retains the portrait layout and never changes to landscape. Actually, I'll live with that for this app. I would like to know why adding the keyboard stuff took care of it (just orientation, as suggested by Juri, didn't). My device doesn't have a physical keyboard. I've never before needed to do that and I suspect it must have something to do with the app's menu/sub-menu's needing user keyed input.Thanks again!

:D cool, I had the keyboard stuff in my activities, but removed it in my post since it didn't make sense for me :)
