Facing ANR when get identify graphic overlay

MinhPham92

Hi all,

I am facing some ANR with my implement as below and the log for ANR point to our Arcgis map when getting the identify graphic overlay.
Could someone help to check for that?
Please let me know if you need further information

Implementation for touching listener:

onTouchListener =
object : DefaultMapViewOnTouchListener(context, this) {
override fun onSingleTapConfirmed(event: MotionEvent): Boolean {
val screenPoint =
                android.graphics.Point(event.x.roundToInt(), event.y.roundToInt())
val identifyGraphic = mMapView.identifyGraphicsOverlayAsync(
                graphicsOverlay,
                screenPoint,
10.0,
false,
                Int.MAX_VALUE
            )

try {
val identifyGraphicsOverlayResult = identifyGraphic.get()
val graphics = identifyGraphicsOverlayResult.graphics
            } catch(e: Exception){
                // print log here
            }
      return super.onSingleTapConfirmed(event)

Hello! It looks like the ANR is most likely caused by this line:

val identifyGraphicsOverlayResult = identifyGraphic.get()

 ListenableFuture.get() will block the current thread until the result is available. In 100.15 and previous versions of the SDK, we recommend you use a callback pattern instead:

val screenPoint = android.graphics.Point(event.x.roundToInt(), event.y.roundToInt())
val identifyGraphicsOverlayResultFuture = mMapView.identifyGraphicsOverlayAsync(
  graphicsOverlay,
  screenPoint,
  10.0,
  false,
  Int.MAX_VALUE
)

identifyGraphicsOverlayResultFuture.addDoneListener {
  try {
    val identifyGraphicsOverlayResult = identifyGraphicsOverlayResultFuture.get()
    val graphics = identifyGraphicsOverlayResult.graphics
  } catch(e: Exception){
    // print log here
  }
}

For more information, you could check out this sample. It doesn't use MapView.identifyGraphicsOverlayAsync(), but it does use the same pattern.

Hope this helps!
