MobDev.ReleaseAndroid (mob_dev v0.3.37)

Copy Markdown View Source

Builds the signed release AAB for a Mob Android app.

Called by mix mob.release --android. The pipeline:

  1. Download the Android OTP runtime (arm64) if not already cached.
  2. Copy the OTP tree to a temp staging dir and add:
    • App + dep BEAMs (flattened into {app_name}/)
    • App priv/ → {app_name}/priv/
    • exqlite BEAMs → lib/exqlite-{vsn}/ebin/ (OTP lib structure needed for :code.lib_dir(:exqlite) to resolve correctly at runtime)
  3. Run MobDev.OtpAssetBundle.build/2 — strips unused OTP libs and optional BEAM chunks, then zips the tree to assets/otp.zip.
  4. Run ./gradlew bundleRelease — signs the AAB using the keystore configured in android/keystore.properties.

MobBridge.extractOtpIfNeeded() (Kotlin) extracts otp.zip into <filesDir>/otp/ on first launch. Without this zip the app crashes immediately — the BEAM has no runtime or application BEAMs to load.
