What methods can ensure synchronization of actions in coroutines?

To synchronize actions in coroutines in Android (Kotlin), several approaches can be used:

• Mutex — provides mutual exclusion, allowing only one coroutine to execute the critical section of code.

• Channels — enable data transfer between coroutines and synchronize their work.

• SharedFlow and StateFlow — for reactive exchange of state and events between coroutines.

• withContext(Dispatcher) — switches the execution context to manage execution order.

• Job and CoroutineScope — manage the lifecycle of coroutines, canceling and waiting for completion.

Example of using Mutex:

val mutex = Mutex()

suspend fun criticalSection() {
    mutex.withLock {
        // Code that should be executed by only one coroutine at a time
    }
}
