Can you tell how you implemented restrictions and limitations within the service?

Restrictions in Android services can be implemented in several ways:

• Access restrictions to functions: through user rights or app state checks.
• Rate limiting: for example, using timers or counters to prevent too frequent actions.
• Using database constraints: such as cache size limits or the number of stored objects.

Example of limiting button clicks to prevent multiple triggers:

var lastClickTime = 0L

button.setOnClickListener {
    val currentTime = System.currentTimeMillis()
    if (currentTime - lastClickTime > 1000) { // 1 second
        lastClickTime = currentTime
        // Handle click
    }
}

This approach helps avoid errors and service overload.
