Google mentions that “The Android N Preview SDK” is required for a Daydream app, which should use an SDK API later than Android SDK API 23, but Epic claims that this is not possible here and here, even though Daydream support is supposed to be available in UE 4.12.
Should we be still be using android-21 to build UE Daydream apps for Android N Preview, or does the N requirement only hold for Google’s VR SDK? (Google also seems to think this will only work for a Nexus 6P. True for Unreal as well?)
I’ve been trying for about a week setting up a Daydream app, but I don’t know which Android APIs I should be starting with.
