Steps to reproduce

1. Open screen that use mapBox i am using SupportMapFragment
2. Lock device for more that one minute without closing the app then open again.
3. App is getting crashed.

Expected behavior

App should not crash.

Actual behavior

App is crashing if user unlock device after few minutes.

Configuration

Android versions: 7.1.2
Device models: Redmi 4
Mapbox SDK versions: 6.3.0

Haven't been able to reproduce this, is this crash specific to Redmi 4?

[rahulabrol]

It might be device specific but I am testing it from last 2 days on Redmi 4 and getting it again and again. I really need some help.

[tobrun]

Would you be able to provide a minimal reproducible example?

[dacheng81]

Hi @tobrun, I have been seeing a similar crash that results in A/libc: Fatal signal 11 (SIGSEGV), code 1, and here's what we do to reproduce this bug reliably:

We have a map with a person marker, which we draw using symbol layer. When the map is ready, we create a symbol layer and we don't remove it.

We would like to show the position and orientation of the person marker, so we set the source layer repeatedly as our location/compass sensors continuously update us. We call map.getSourceAs<GeoJsonSource>(sourceName).setGeoJson(feature). Our feature is created by calling Feature.fromGeometry and we call addNumberProperty("ROTATION", rotation).

It works great until it hits a certain limit -- I've seen the crash consistently on about 4500 setGeoJson() calls. I've also seen it crash at around 6700 calls, depending on device and other background apps, perhaps. But it's always reproducible, and it doesn't seem to be correlated to how fast we call setGeoJson. For instance, If we call it 5 times a second, it would crash after ~15 minutes. If we call it once per second, it would crash after ~75 minutes. Even destroying the map and recreating it seems to not extend the number of sets. e.g. I call setGeoJson() 2000 times then quit the screen which calls map.onStop() and map.onDestroy(), then recreate the fragment, and I get to 2500 sets and it crashes, rather than 4500.

I've also tried creating new source layer and symbol layers but the total setGeoJson seems to be fairly constant.

I've looked for ways to animate our marker but did not find anything.

For the time being we're optimizing our code to set source layer as infrequently as possible, but this only postpones the inevitable it seems.

Any help would be greatly appreciated!

[tobrun]

@dacheng81 why are you creating the source object every time? This is an expensive operation and if possible should be avoided. Store that GeojsonSource as a field in your activity/fragment class and call setGeoJson on that instead.

Fwiw, https://github.com/mapbox/mapbox-plugins-android/tree/master/plugin-locationlayer applies this and we aren't having the issues that you are mentioning.

[dacheng81]

Hi @tobrun, let me see if I understand you correctly. You're saying the map.getSourceAs(sourceName) call is expensive and we should avoid it. So have a geoJsonSource = map.getSourceAs(sourceName) early on and then only call geoJsonSource.setGeoJson(feature).

If that's correct -- I just tried it with our code and no, it still crashes in the same way, after ~ 5000 setGeoJson(feature) calls. (As a side note, if feature is simply derived from FeatureCollection.fromFeatures(ArrayList()), i.e. empty, it still crashes.

I looked up plugin-locationlayer and if I'm not mistaken, this file: https://github.com/mapbox/mapbox-plugins-android/blob/master/plugin-locationlayer/src/main/java/com/mapbox/mapboxsdk/plugins/locationlayer/LocationLayer.java is what you were referring to? In there, refreshSource() calls getSourceAs(LOCATION_SOURCE) every single time. You're saying you don't see a crash even when it does create the source object every time? Is it possible that people who use this plugin don't end up modifying the feature too frequently and thus not refreshing the source into the thousands of times?

Thanks for your help!
