I see about 500 crash-reports in the Google Play console of our live-app and all of them look like this:

In our app, we set the markingMode-flag is set to 'none'.
As all the logs contain 'com.tns.gen.com.lambergar.verticalviewpager...', I guess this issue is related to the nativescript-pager plugin.

Which platform(s) does your issue occur on?

  • Android
  • device

Please, provide the following version numbers that your issue occurs with:

  • CLI: 5.4.0
  • Cross-platform modules: 5.4.2
  • Runtime(s): tns-android 5.4.0
  • Plugin(s): 9.5.4

Please, tell us how to recreate the issue in as much detail as possible.

Describe the steps to reproduce it.

It is really hard to reproduce this issue. Sometimes it takes 2 minutes, sometimes it does not occur while testing for about 10 minutes.

Is there any code involved?

Right now, it is pretty hard to extract this scenario in a sample app, where you can reproduce this issue.
As all of the crash reports are related to the setPrimaryItem method, I hope you can figure out what is happening here without any sample projects.

@triniwiz we released an update of our app using the latest pager plugin v.12.0.0.alpha-8 and we still see many crash reports in the Google Play Console, like this:

We also see some newer crash reports (that we did not see using pager plugin v. 10.0.0), that also seem to occur randomly (not reproducable on our side).

As I already mentioned, we cannot reproduce this ourselves on our test devices and we do not know if one of those crashes occur when changing the page within the pager or if it occurs only when the users navigate away from the page containing the pager component and then navigate back to it or navigates forward to the page with completely different data (different amount of pages, different content,...).

Do you see any chance that this might be fixed soon?

I don't use FragmentPagerAdapter also this is mentions the v1 of the pager which is used by {N} tabs androidx.viewpager.widget.ViewPager.dataSetChanged(ViewPager.java:1070) my guess is you are using one of the tabs component .... related issue NativeScript/NativeScript#7904

@triniwiz thanks for your reply. I double checked those crash reports in Firebase Crashlytics and indeed, during most of those crashes, the user was not active on the page containing the Pager component, in addition Firebase was showing me some older crash reports, even when filtering only the latest ones... and also the crash logs looked very similar.. very confusing :D
