Flutter useHybridComposition cause crash

[paulVulog]

Environment

• Android OS version: at least API 29 (10)
• Devices affected: Samsung S9
• Maps SDK Version: Flutter Mapbox-gl v0.16.0

Observed behavior and steps to reproduce

When running an app with MapboxMap.useHybridComposition = true; and doing some multitouch on the map, you can easily get some app crashes.

here are the produced logs :

Way to reproduce using the Mapbox Gl sample app:

• Be sure to have the MapboxMap.useHybridComposition = true; correctly initialized in lib/main.dart:

  @override
  void initState() {
    initHybridComposition();
    super.initState();
  }

  /// Determine the android version of the phone and turn off HybridComposition
  /// on older sdk versions to improve performance for these
  ///
  /// !!! Hybrid composition is currently broken do no use !!!
  Future<void> initHybridComposition() async {
    MapboxMap.useHybridComposition = true;
  }

• Using the Full_Screen_Map section of the app, replace the Build method in lib/full_map.dart by :

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
        floatingActionButton: Padding(
          padding: const EdgeInsets.all(32.0),
          child: FloatingActionButton(
            child: Icon(Icons.swap_horiz),
            onPressed: () => setState(
              () => isLight = !isLight,
            ),
          ),
        ),
        body: Stack(
            children: [MapboxMap(
              styleString: isLight ? MapboxStyles.LIGHT : MapboxStyles.DARK,
              accessToken: MapsDemo.ACCESS_TOKEN,
              onMapCreated: _onMapCreated,
              initialCameraPosition: const CameraPosition(target: LatLng(0.0, 0.0)),
              onStyleLoadedCallback: _onStyleLoadedCallback,
            ),
          Center(
            child: Container(
              width: 50,
              height: 50,
              color: Colors.green,
            ),
          ),
        ]
        ));
  }

This will simply add a widget on top of the map to reproduce the crash.

• Run the app, go to the FullScreenMap section
• To get the crash, simply do a multitouch tap as follow :

One digit on the map
The Other One on the green widget
Tap both at the same time.

You will get a crash.

It only crash if you tap a widget (flutter) stacked on top of the map (nativ view because of .useHybridComposition = true)

Expected behavior

We should not get any crash. Minimum requirement is to silently catch the exception. (this is what google maps seems to do - see below)

Notes / preliminary analysis

I have tested the same behavior on the GoogleMap sample app : https://github.com/flutter/plugins/tree/main/packages/google_maps_flutter/google_maps_flutter

I am able to reproduce the same kind of issue, Except that the google map do not Crash. There is only some flutter Error log :

The issue is tracked in this repository - forwarded to the main Android Mapbox repository here:

@paulVulog thank you for reporting, I will transfer this ticket to the appropriate repo.

@ZiZasaurus any status on this ? It is really impacting. Where did you transfer this issue to ?

Hi, similiar backtrace here appxmod/diodict-decompiled@7199009

If I filter out ACTION_POINTER_DOWN，the native crash will become the “pointerIndex out of range” Exception：

if (actionMasked!=MotionEvent.ACTION_POINTER_DOWN) {
	try {
		boolean flingEvent = this.flingDetector.onTouchEvent(event);
		if (flingEvent) {
			// this.flingDetector = new GestureDetector(getContext(), this);
			return flingEvent;
		}
	} catch (Exception e) {
		e.printStackTrace();
	}
}

I resolved this issue by create new Flutter Engine with custom MyPlatformViewController extend PlatformViewController
flutter/engine@991471b

MyPlatformViewController:

class MyPlatformViewsController : PlatformViewsController() {
    override fun toMotionEvent(
        density: Float,
        touch: PlatformViewsChannel.PlatformViewTouch?,
        usingVirtualDiplays: Boolean
    ): MotionEvent {
        val motionEventId = MotionEventId.from(touch!!.motionEventId)
        val trackedEvent = MotionEventTracker.getInstance().pop(motionEventId)

        // Pointer coordinates in the tracked events are global to FlutterView
        // framework converts them to be local to a widget, given that
        // motion events operate on local coords, we need to replace these in the tracked
        // event with their local counterparts.

        // Pointer coordinates in the tracked events are global to FlutterView
        // framework converts them to be local to a widget, given that
        // motion events operate on local coords, we need to replace these in the tracked
        // event with their local counterparts.
        val pointerProperties = parsePointerPropertiesList(
            touch!!.rawPointerPropertiesList
        ).toTypedArray()
        val pointerCoords = parsePointerCoordsList(
            touch!!.rawPointerCoords, density
        )
            .toTypedArray()

        return if (!usingVirtualDiplays && trackedEvent != null) {
            MotionEvent.obtain(
                trackedEvent.downTime,
                trackedEvent.eventTime,
                touch!!.action,
                touch!!.pointerCount,
                pointerProperties,
                pointerCoords,
                trackedEvent.metaState,
                trackedEvent.buttonState,
                trackedEvent.xPrecision,
                trackedEvent.yPrecision,
                trackedEvent.deviceId,
                trackedEvent.edgeFlags,
                trackedEvent.source,
                trackedEvent.flags
            )
        } else MotionEvent.obtain(
            touch!!.downTime.toLong(),
            touch!!.eventTime.toLong(),
            touch!!.action,
            touch!!.pointerCount,
            pointerProperties,
            pointerCoords,
            touch!!.metaState,
            touch!!.buttonState,
            touch!!.xPrecision,
            touch!!.yPrecision,
            touch!!.deviceId,
            touch!!.edgeFlags,
            touch!!.source,
            touch!!.flags
        )

    }

    private fun parsePointerPropertiesList(rawPropertiesList: Any): List<PointerProperties> {
        val rawProperties = rawPropertiesList as List<Any>
        val pointerProperties: MutableList<PointerProperties> = java.util.ArrayList()
        for (o in rawProperties) {
            pointerProperties.add(parsePointerProperties(o))
        }
        return pointerProperties
    }

        properties.toolType = propertiesList[1] as Int
        return properties
    }

    private fun parsePointerCoordsList(rawCoordsList: Any, density: Float): List<PointerCoords> {
        val rawCoords = rawCoordsList as List<Any>
        val pointerCoords: MutableList<PointerCoords> = ArrayList()
        for (o in rawCoords) {
            pointerCoords.add(parsePointerCoords(o, density))
        }
        return pointerCoords
    }

    private fun parsePointerCoords(rawCoords: Any, density: Float): PointerCoords {
        val coordsList = rawCoords as List<Any>
        val coords = PointerCoords()
        coords.orientation = (coordsList[0] as Double).toFloat()
        coords.pressure = (coordsList[1] as Double).toFloat()
        coords.size = (coordsList[2] as Double).toFloat()
        coords.toolMajor = (coordsList[3] as Double * density).toFloat()
        coords.toolMinor = (coordsList[4] as Double * density).toFloat()
        coords.touchMajor = (coordsList[5] as Double * density).toFloat()
        coords.touchMinor = (coordsList[6] as Double * density).toFloat()
        coords.x = (coordsList[7] as Double * density).toFloat()
        coords.y = (coordsList[8] as Double * density).toFloat()
        return coords
    }
}

In MainActivity (your main flutter activity):

    override fun provideFlutterEngine(context: Context): FlutterEngine? {
        return FlutterEngine(
            context,
            null,
            FlutterJNI(),
            MyCustomFlutterEngine(),
            Companion.flutterShellArgs.toArray(),
            false
        )
    }
