Instructions to add the screen params of new iOS devices to the Cardboard SDK
Stay organized with collections
Save and categorize content based on your preferences.
Each year, new iOS devices are released. In order to make the Cardboard SDK
work with these new devices, it is required to update screen_params.mm.
What needs to be updated
Take a look at the history of screen_params
to ensure that the correct lines are being updated.
Update the XR Plugin with the new screen param files
If the XR Plugin is being used, it is required to generate a new
GfxPluginCardboard.a with the updated screen_params.mm file.
Follow the steps in the "Download and build the demo app" section from the
Quickstart
up to step 2 to open Cardboard.xcworkspace workspace in XCode. Select the sdk
module and then Generic iOS Device as the target device (or choose to build
for a specific phone if that suits your needs better). Build the sdk module,
copy the generated .a file and replace the GfxPluginCardboard.a file in
cardboard-xr-plugin/Runtime/iOS/.
