I can consistently reproduce the problem on my Android 7.0 emulator.
Tell us about the problem
My App crashes on Android 7.0, if I have switched page and open Android 7.0's split screen.
Which platform(s) does your issue occur on?
Android 7.0
Please provide the following version numbers that your issue occurs with:
- CLI: 2.5.3
- Cross-platform modules: 2.5.2
- Runtime(s): tns-android@2.5.0
- Plugin(s): none
Please tell us how to recreate the issue in as much detail as possible.
- create an angular project with: tns create hallo-world --ng
- set pageTransition="slideTop" on the nsRouterLink-label in app/item/items.component.html
- Run the App on an Android 7.0 emulator
- Tap an item and tap back
- Hold the window-switch-button down until the split-screen comes up.
- The App should now have crashed with the "View already has a parent"-error.
I don't know if it's caused by the same problem, but I've seen the error many times. But I haven't been able to reproduce it, making it hard to write a proper bug report on the issue.

Is there code involved? If so, please share the minimal amount of code needed to recreate the problem.
I've added a test project here:
