Two issues prevented the app from running on the Karoo 2 (armeabi-v7a, Android 8.1):
1. Debug builds loaded the JS bundle from Metro (localhost:8081) rather than
embedding it. Fixed by setting debuggableVariants = [] in the react {} block,
which tells the RN Gradle plugin to bundle JS for all variants including debug.
2. splits.abi only included arm64-v8a, so the CMake/NDK build (which generates
libappmodules.so — the TurboModule registry) never ran for armeabi-v7a.
Result: PlatformConstants TurboModule not found, app stuck on splash.
Fixed by adding armeabi-v7a to the splits.abi include list.
