If there is an infinite loop inside a coroutine in Android (for example, using Kotlin Coroutines), then when the application terminates, this loop usually stops because the application process ends, and all its threads and coroutines are destroyed.

However, if the coroutine is launched in a global scope (for example, GlobalScope), and the application is not properly terminated, then the coroutine may continue to run, leading to memory leaks or other issues.

Therefore, it is recommended to launch coroutines within the lifecycle of components (for example, ViewModelScope or lifecycleScope) so that they are automatically canceled when the component is destroyed.

Example of canceling an infinite loop in a coroutine:

val job = CoroutineScope(Dispatchers.Default).launch {
    while (isActive) { // isActive checks if the coroutine is canceled
        // work
        delay(1000)
    }
}

// When the application or component is finished, call
job.cancel()

Thus, the infinite loop inside the coroutine will be interrupted when the application is properly terminated or the coroutine is canceled.
