nix android.sh

FFmpegKitNext uses these Android entrypoints:

• Recommended Nix wrapper: ./nix-android.sh -p PROFILE [OPTION]... [VAR=VALUE]...
• Direct script: ./scripts/start-android.sh [OPTION]... [VAR=VALUE]...

The build options are the same for both entrypoints. The Nix wrapper also supports -p, --profile and --list-profiles.

By default, the Android build enables five architectures: armeabi-v7a, armeabi-v7a-neon, arm64-v8a, x86 and x86_64. No optional external libraries are enabled by default.

When compilation ends, an Android Archive (.aar) is created under prebuilt unless --no-archive is used.

Usage with Nix:

./nix-android.sh -p android-r27d [OPTION]... [VAR=VALUE]...

Usage without Nix:

./scripts/start-android.sh [OPTION]... [VAR=VALUE]...

Specify environment variables as VARIABLE=VALUE to override default build options.
