make_frame_tile.py reads the release tile from the git-ignored
assets/background, takes the Quest help off it, draws the Frame's, and
writes it into build/frame-assets. The frame build type's assets override
the release tile with it, a gradle task runs it before mergeFrameAssets.
Quest and Pico builds are untouched. If the tile or Pillow and numpy are
missing, the Frame build goes on with the release tile and a warning.
The Frame runs Android apps in a container (Lepton) that has no OpenXR
loader broker, so the APK needs its own loader. This adds a "frame" build
type: ./gradlew assembleFrame.
It's release plus:
- applicationId .frame, minSdk 30 (the container is Android 11)
- a manifest overlay that drops the headtracking requirement and the
Quest/Pico metadata, since the install fails with it
- the Khronos loader 1.1.63, fetched from Maven Central at build time,
checked against a SHA-256 and unpacked into build/ (not committed)
- L1VR_STEAM_FRAME for the native code, BuildConfig.STEAM_FRAME for Java
Quest builds don't see any of this. I also added the gradle wrapper script
to Projects/Android, since the wrapper jar and properties were already
there, and -Wall for the VR sources.
Haven't run it on the headset yet.
