Inline functions in Kotlin (commonly used in Android development) optimize function calls, especially when working with lambdas.

When to use inline functions:

  • If a function accepts lambda expressions and is called frequently, inline avoids creating additional objects and calls.
  • To improve performance in critical speed places.
  • To implement higher-order functions with the ability to use noinline and crossinline to control lambda behavior.

Example:

inline fun performOperation(operation: () -> Unit) {
    println("Before operation")
    operation()
    println("After operation")
}

performOperation {
    println("Executing operation")
}

Here, the body of operation is inserted directly into the call code, reducing overhead.

However, do not use inline for large functions, as it will increase the bytecode size.
