@rakeshgirase which controls are used in your application - is it possible to provide a sample demo that can reproduce the issue in production?

rakeshgirase · 2018-03-06T09:58:29Z

Thank you for your response @NickIliev. My application can be found at https://github.com/rakeshgirase/QSB. I don't really have much details for reproducing this issue. I just got an email from Google highlighting this Fatal Issue. I have forwarded that email to you just in case if it helps.

NickIliev · 2018-03-23T11:50:20Z

@rakeshgirase I am not able to reproduce the issue - do you have any specific steps that I can follow to throw the error?

gsmedley · 2018-03-24T14:23:20Z

Same issue here. Started running monkey tests on our application. Usually after about 10/15 min we'll see this:

rakeshgirase · 2018-03-24T15:10:59Z

@NickIliev I too dont know how to produce that error. Thought of raising it just because I got this info from google.

VladimirAmiorkov · 2018-03-24T22:05:05Z

Hi @rakeshgirase ,

The #128 issue was related to the RadGauge component which I was not able to find to be used inside your app so I would guess this is not the same issue. Looking at what @gsmedley provided he is actually not using the nativescript ui components at all so this might be an issue with one of the tns-core-modules components. Al tho doing a random monkey test on an app for 15 minutes straight and after that getting an error may be an issue regarding GC in the android run time.

This needs to be research further so if you can provide any additional information please do so. @gsmedley can you share your app with is that you ran the monkey test on of possible?

gsmedley · 2018-03-25T10:55:44Z

Hi @VladimirAmiorkov,

Thanks for the reply. That wasn't a full list of the components we are using, I'll add that to the end of this message.

I can't share the app, it's an in-house application that relies on a private server. But I will share all of the results of my stress testing. Currently I am seeing 4 different crashes that happen within about 15/20 minutes

#561 - This one.
#1048 - Related to using the back button with a "clearHistory"
#1151 - Also related to the back button with a "clearHistory"
OutOfMemory - This was with the graphing component, could be the app caching data, need to investigate further.

Full list of components. Note that I've excluded the custom components from the tests: nativescript-anyline, nativescript-idscanner & nativescript-medicalsensors.

Tronix117 · 2018-05-10T14:58:48Z

I got the exact same issue with RadSideDrawer when resuming app and it is kind of really blocking for us.

Here is the layout (NS4+Vue)

(Don't mind the syntax)

RadSideDrawer(
  @loaded="loaded"
  height="100%" width="100%"
)
  Frame('~mainContent')
    component(:is="startingComponent" height="100%" width="100%")
  AbsoluteLayout('~drawerContent')

edusperoni · 2018-05-10T17:27:02Z

Yeah, I'm having the same issue. I just got the sidedrawer ng app template and added some components in one of the screens. If I press the back button repeatedly after navigating through the app a bit, this error appears

anuragd7 · 2018-06-04T16:22:26Z

I am experiencing the same error, interestingly also on android Api 23 version 6.0.1.
I am running tns 3.4.2. Not using the drawer template though

Am reproducing the crashlytics log below:
