Android app crashes on rotation to landscape

[inclement]

My kivy app crashes when rotated from portrait to landscape via phone rotation with the 'orientation=sensors' option. An example logcat output is at https://gist.github.com/inclement/6245730

I've tested with another (much simpler) app and got the same behaviour, and tshirtman reports also seeing it.

I'm a bit confused, i compiled a debug distro yesterday to track it
down, and building toutchracer/showcase with orientation=sensors with it
got me two fully working apk, no crash when rotating. My debug build
mostly changes -O3 to -O0 and removes stripping of libs in python and
libs building in the distro.

The rotate crash will happen if you use a target SDK higher than 12. The default in py4a is 8, so you will not notice this problem unless you specify --sdk in the build command.

To fix this, we need to figure out what change in SDK 13 is causing the rotation to fail. Change information is at http://developer.android.com/reference/android/os/Build.VERSION_CODES.html#HONEYCOMB_MR2

[tshirtman]

"New FEATURE_SCREEN_PORTRAIT and FEATURE_SCREEN_LANDSCAPE features were introduced in this release. Applications that target previous platform versions are assumed to require both portrait and landscape support in the device; when targeting Honeycomb MR1 or greater the application is responsible for specifying any specific orientation it requires"

Doh, maybe we just need to add these flags to the xml? >_>

Did you try this fix with API <= 12 ? With API 13 and 14 it works, but with API 8,11, and 12 I get results like http://pastebin.com/7CZLwXZB

[brousch]

#8f4d23a allows the APK to compile on API <= 12, but the resulting app crashes if you rotate the screen.

Is this still open on API < 12?

This happens to me too.

orientation = all in buildozer.spec. Rotating device crashes the application without very meaningful debug information. Buildozer default minapi settings.

Below is adb logcat.
