Application is crashing on android 7


#1

Hi,
We created mobile app using cordova and ionic. The main part of application is map which is implemented with openlayers3. On map there is one raster layer and pretty many vector layers. Those vector layers geoemtries are loaded from local spatialite database. After playing for some time with map (zooming,panning, switching off/on layers) app crashes. It didn’t happen on previous Android 6. The direct error says “out of memory” and probably comes from webview. I tried diffrent webviews => crosswalk, chrome, system component, app is always eventually crashing.
I am not sure if this the right place to write (I am not sure what is the correct cause of crash) but I am out of ideas at the moment, so maybe here someone faced similar problems.
I am using cordova 6.2.0 (however did try also with 6.5.0 and also crashing),cordova android 6.1.2. I made my tests on S7 Edge 935F Android 7.0.

So, it means your app is doing so much that you’re running out of allocated ram so it’s forcing it to quick instead of crashing the entire OS.

The only things I can think to recommend are:
1- Don’t do so much in the app, see what you can optimize
2- Make sure you don’t have plugins that you don’t need
3- Use some android debugging tools to monitor memory usage and that may help identify what specifically is causing it to go so high

If this is happening on a new flagship phone, it’s sure to almost instantly crash on any other android that has less available memory.

Hi, thanks for suggestions. I will try some of those.

Hi,

Did you find any solution for your issue ? I am facing the same kind of issue. i’ve used ionic’s infinite scroll to load text/image/video in a list. App works fine on all ios and android devices but it crashes on Nexus 6(7.1.1) while scrolling. It crashes on real device only not emulator. Below is the logcat of the crash:

Hi,
in our case problem was related with map and layers rendering .We had to optimize our rendering engine , we started with stopping recreation of some objects. It wasn’t any configuration or plugin issue.
Maybe in your case similar thing is happening, some objects are recreated when scrolling.

Hi,

Yes, this might be the case. But, what’s surprising is that the crash is only happening on Nexus Devices(7.1.1) and now i can’t decide if it is a device issue or there’s something wrong in the code.

Thanks
