In the modern world of mobile development, the term APK (Android Package Kit) typically conjures images of compiled Java or Kotlin code—static, binary, and difficult to modify. However, a powerful niche has emerged that flips this paradigm on its head: the Scriptable APK .
Create a simple Activity that reads a script from assets/script.lua and executes it.
class MainActivity : AppCompatActivity() override fun onCreate(savedInstanceState: Bundle?) super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) val button = findViewById<Button>(R.id.runScriptButton) button.setOnClickListener runLuaScript()
