In Android development, multi-threaded programming is an inevitable part. As a modern programming language, Kotlin provides a wealth of tools and syntax to simplify the complexity of multi-threaded programming. One of the important concepts is thread lock, which is used to ensure synchronized execution between multiple threads. This article will introduce in detail the method of using Kotlin for thread synchronization in Android and provide corresponding source code examples.
In Kotlin, we can use the synchronized keyword to implement thread locks. The synchronized keyword can be applied to member functions or code blocks of a class to ensure that only one thread can access locked code at the same time. Here is a simple example that demonstrates how to use the synchronized keyword to ensure thread safety:
class Counter {
private var count = 0
fun increment() {
synchronized(
