Random crash when tap on Marker

PrasadPotale — Wed, 06 Jul 2016 19:53:52 GMT

Found few crashes on Crashlytics, with following details, any help about the cause of issue, its occurring when we tap on map.

I get the same thing in a few scenarios. It seems to happen when I push or present a new view controller and usually only when I have GPS turned on.

Have you found any solution to this?

Re: Random crash when tap on Marker

PrasadPotale — Mon, 18 Jul 2016 13:09:11 GMT

No I've posted this question on Stack overflow as well, but didn't get any response yet.

I'll update you, if I found any solution for it. Also let me know if you found any solution.

Marius UrsacheRyan OlsonDivesh Goyal Hey guys, can you please help us to identify this issue.

Re: Random crash when tap on Marker

RyanOlson1 — Mon, 18 Jul 2016 16:05:51 GMT

Can you try turning hit-testing off on a per-layer basis to narrow down what layer is causing the crash?

Re: Random crash when tap on Marker

ChristopherMilack1 — Mon, 18 Jul 2016 16:23:24 GMT

Hey Prasad/Ryan,

Sorry to hijack this thread but I've run into a similar issue and had some detailed repro cases that might be helpful.

This was my workflow:

Show view controller with AGSMapView in navigation controller (Location Display turned on) -
- Do not interact with the map view at all
Push a new view controller on the navigation controller
Click back to return to the map view controller

At this point, if GPS is still on and the users location is offscreen, I will get a similar crash when I tap the map. However, if I pan the map first, then tap, I have no issues.

As a workaround, I started shutting off the GPS before pushing the new view controller and that resolved my issues. It's been a while since I did that work but I did the exact test you described (removing layers), and the crash did not seem to correlate to any specific layer. I can run these tests again if it would be helpful.

Here's another post I made when this first happened. The crash output was slightly different but the issue seemed to be the same. This frame buffer exception was consistent and repeatable but the _platform_memmove crash that Prasad was seeing was more intermittent for me. Both occurred when tapping on the map after returning from another view controller.

Frame_buffer_OGL::init_ FAILED when tapping map

Hope that is helpful.

Chris

Hello Ryan Olson,

Thanks for replying, following is the code which I have used to add Picture Marker Symbol, the issue is random and when I tap on the marker the above crash issue is occurring,

self.markerGraphicsLayer = AGSGraphicsLayer(fullEnvelope:envelop ,renderingMode:AGSGraphicsLayerRenderingMode.Dynamic)

self.agsMapView.addMapLayer(self.markerGraphicsLayer, withName:Constants.graphicsLayerNames.MarkerGraphicsLayer)

func createMarkerGraphicsWithBadgeCount(point:AGSPoint,image:UIImage ,graphicAttributes :[NSObject:AnyObject] )

{

var graphicPoint:AGSPoint!

var graphicSymbol:AGSPictureMarkerSymbol!

graphicPoint = AGSPoint(x: point.x, y:point.y, spatialReference:self.agsMapView.spatialReference)

graphicSymbol = AGSPictureMarkerSymbol(image:image)

let graphics = AGSGraphic(geometry: graphicPoint, symbol:graphicSymbol, attributes:graphicAttributes)

self.markerGraphicsLayer.addGraphic(graphics)

}

//Delegate method to handle tap on marker

func didTapOnGraphics(graphic:AGSGraphic, coordinate:CLLocationCoordinate2D)

{

//Here new controller will be presented

}

Hi Chris, I'll try the scenario you have mentioned, and let you know, if I can reproduce it.

Re: Random crash when tap on Marker

RyanOlson1 — Tue, 19 Jul 2016 16:25:07 GMT

can you try AGSGraphicsLayerRenderingMode.Static?

Re: Random crash when tap on Marker

PrasadPotale — Tue, 19 Jul 2016 19:44:31 GMT

Now I've changed it to Static mode but now if I rotate map, markers also getting rotated, I'll test more on it and let you know, if it fixes that crash or not. Thanks.

Re: Random crash when tap on Marker

ChristopherMilack1 — Wed, 27 Jul 2016 16:18:39 GMT

Did that fix work for you?

Re: Random crash when tap on Marker

PrasadPotale — Tue, 02 Aug 2016 09:43:27 GMT

No Chris, it didn't work for me, the issue is still occurring.

DiveshGoyal — Tue, 02 Aug 2016 21:19:17 GMT

Is it possible you're tapping on the map to hittest the graphic before the graphics layer or other layers have finished drawing? I don't know if that would cause this problem, it's just a shot in the dark. If you have a repro case that can reliably produce the problem it'll be easier to troubleshoot.

Re: Random crash when tap on Marker

PrasadPotale — Wed, 03 Aug 2016 14:53:00 GMT

Thanks Divesh, for replying.

We have verified it on app, layerDidLoad getting called properly for all layers,

In app we have AGSMapView on two View controllers

ViewController1 : On which it loads map with multiple polygons
On tap of polygon from ViewController1, it pushes ViewController2
ViewController2 : it loads map with a single polygon and some markers on it.
On tap of marker it presents ViewController3

5. App is getting crashed when ViewController3 presentation is in progress with following crash logs.

We are getting two different type of crash logs, but for both cases crash reproduction steps are same.Following is another one, posted another question for this

https://community.esri.com/thread/179502

Complete Crash Logs: 1.https://www.dropbox.com/s/g08og9sfmkgqr2z/AGSMapRenderer_drawRequested_Crash_Log.txt?dl=0

2. https://www.dropbox.com/s/dim1fcx17bdwtro/AGSMapView_singleTap_Crash_Log.txt?dl=0

Here are some queries:

We are creating separate instances of AGSMapView, separate layers instances on both view controllers ViewController1 and ViewController2,

so will it create a issue?

2. On both ViewController1 and ViewController2 we are calling self.agsMapView.locationDisplay.startDataSource()

On ViewController3 we need users current location so we are checking for it by using CLLocationManager, any chances that this will create a issue.

Let me know if you need any more details.
