The generated scaffold was a Views-based Material 2 shell with no activity,
no Kotlin sources, and a placeholder package. Replace it with the real base
the conversion work builds on.
Build configuration, with three AGP 9 specifics that contradict most
tutorials still in circulation:
- AGP 9 has built-in Kotlin. Applying org.jetbrains.kotlin.android now fails
the build, so the absence of that plugin is deliberate, not an oversight.
- The Compose compiler plugin is still separate and must be applied, pinned
to 2.2.10 to match the kotlin-gradle-plugin AGP 9.3.1 brings transitively.
Pinning it to the newest Kotlin release instead would mismatch.
- android.kotlinOptions {} was removed; jvm configuration moves to a
top-level kotlin { compilerOptions {} }.
Java compatibility goes 11 -> 17 (AGP 9 requires JDK 17), abiFilters
restrict packaging to arm64-v8a and x86_64, and jniLibs packaging is set
uncompressed so the APK zip-aligns native libraries on 16 KB boundaries.
Every dependency version in the catalog was checked to resolve against
Google Maven rather than copied from documentation. Note that KSP has moved
to standalone versioning (2.3.11) and no longer uses the old
<kotlin>-<ksp> scheme; it is catalogued but left unapplied until Room lands.
Set applicationId to dev.jasonmross.mediaconverter. com.example.* is
rejected by the Play Console, and the application ID is permanent once
published, so it has to be right before the first upload. The display name
is just a string resource and stays changeable.
Document the split license posture: source is MIT, but the distributed
binary will be GPL-3.0 because it bundles FFmpeg built with x264/x265.
LICENSES/README.md records why, including that libass is ISC rather than
GPL, so subtitle burn-in is not what forces the GPL choice.
