Hi Dave,
Please refer below steps to force orientation to landscape:
1. Make sure only landscape permission is available on your build environment
Only add android.hardware.screen.landscape.xml to your makefile by below
command:
PRODUCT_COPY_FILES +=
frameworks/native/data/etc/android.hardware.screen.landscape.xml:system/etc/permissions/android.hardware.screen.landscape.xml
\
Remove android.hardware.screen.portrait.xml if it exists
2. Add an overlay to force landscape mode
Assume you have device/company/device_x
Create a config.xml file and put it in
device/company/device_x/overlay/framework/base/res/res/values
Contents of config.xml:
<resources>
<bool name="config_forceDefaultOrientation">true</bool>
</resources>
3. Make sure your overlay in config.xml is used
PRODUCT_PACKAGE_OVERLAYS += device/company/device_x/overlay
Done! Your system is always landscape!
Note: This solution only works on Android P or older Android version. From
Android Q, Google changes to use new solution.
Limitation: The app which sets portrait as orientation in AndroidManifest.xml
can’t display properly! Ex: Antutu Benmark.
By the way, I had found solution for above limitation by creating a broadcast
service which tried to convert rotation of the application. But i just forgot
the reference. I will try to find it and share you later!
Best Regards,
KHA Tran
