I have developed an app in Nativescript Angular for Android and IOS. When I send push notifications to the Android app, and the app is in background, the first notification can be opened without any issue. However if I try to open the second notification, the app crashes with the following error

System.err: An uncaught Exception occurred on "main" thread.
System.err: Unable to destroy activity {myapp/com.tns.NativeScriptActivity}: com.tns.NativeScriptException: Calling js method onDestroy failed
System.err: Error: View not added to this instance. View: Frame(274) CurrentParent: undefined ExpectedParent: AppHostView(1)

It looks the app goes to onDestroy and restarts fully when it tries to open the notification. But I only have issues when the second notification is being opened.

My app is using 

Nativescript 6.3.0
tns-core-modules has 6.3.2 version
tns-android has 6.3.1 version 
tns-ios has 6.3.0 version

Any idea on how to fix this?

  • It looks it works when I added android:launchMode="singleTask" to my AndroidManifest – jht Feb 04 '20 at 14:00

  • "singleTask and singleInstance — are not appropriate for most applications, since they result in an interaction model that is likely to be unfamiliar to users and is very different from most other applications." https://developer.android.com/guide/topics/manifest/activity-element#lmode – Przemo May 11 '20 at 06:03

I think you should wrap your page-router-outlet inside a StackLayout, I encoutered this one, was fixed by doing this:

in your app.component.html:

<StackLayout> 
    <page-router-outlet></page-router-outlet>
</StackLayout>
