I am building an Android Accessibility Service. While debbuging it, it shows the following warning:

W/AccessibilityInteractionClient: old interaction Id is: -1,current interaction Id is:372

(The current interaction Id is increasing with 1 for every warning) AccessibilityInteractionClient is not my message tag and I do not invoke this log message anywhere

I could not find any hints towards the origin of this message nor did I find out what the interaction Id represents.

class AccessibilityAutofillService : AccessibilityService() {

    override fun onAccessibilityEvent(event: AccessibilityEvent) {
        when (event.eventType){
            AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED -> {
                handleAccessibilityEvent(event)
            }
            AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED -> {
                handleAccessibilityEvent(event)
            }
            AccessibilityEvent.TYPE_VIEW_FOCUSED -> {
                //ignore for now
            }
        }
    }
}

private fun handleAccessibilityEvent(event: AccessibilityEvent) {
    val packageName = event.packageName
    val root = rootInActiveWindow
    Log.d(_logTag, "event: " + event.eventType + ", package = " + packageName) 
}

Log: Warning appears before my log. Warning appears not only for one of my three selected types but probably all accessibility events

W/AccessibilityInteractionClient: old interaction Id is: -1,current interaction Id is:232
D/MyTag: event: *someEventType*, package = *somePackageName*
W/AccessibilityInteractionClient: old interaction Id is: -1,current interaction Id is:233

  • Maybe it can be useful see the stack to intercept the warning cause https://stackoverflow.com/questions/21071960/android-studio-where-can-i-see-callstack-while-debugging-an-android-app – Roberto Manfreda Apr 12 '19 at 12:32

    How can I use the Threads to find the origin of the warning message? Since it is connected to the Accessibility Service IMO the relevant Threads are the Binders, Thread-3 and Thread-4. – Noah Studach Apr 15 '19 at 12:11
