Hi @vbresults,
I tested your scenario in a sample project on Android device, however, was unable to recreate the issue. For your convenience, I am attaching the project. Please review it and make the needed changes, that will help us in recreating the problem.

Meanwhile, make sure that you have added keyboard|smallestScreenSize|screenLayout|locale|uiMode options in the configChanges in your AndroidManifest.xml file.

For example:

android:configChanges="keyboard|keyboardHidden|orientation|screenSize|smallestScreenSize|screenLayout|locale|uiMode"

Hi @xlmnxp,
I found out that the crash in the project is related to the custom login implemented inside of the TabView's loaded event(disableFocusSearchBar callback method in your code) in posts.component.ts. In disableFocusSearchBar, you are using the removeViewAt native method to remove one of the TabView's child views(this.tabview.nativeElement.android.removeViewAt(1);). This method will remove the needed child view successfully when the page is initially loaded. However, when you make forward and them backwards navigation, you will try to remove the non-existing native child view again. To solve your case, you need first to check if the child view exists and then try to remove it. For example:

disableFocusSearchBar() {
    var searchBar: SearchBar = <SearchBar>this.searchBar.nativeElement;
    if (isAndroid) {
      searchBar.parent.android.setFocusableInTouchMode(true);
      searchBar.parent.android.setFocusable(true);
      searchBar.nativeView.setFocusable(false);
      searchBar.nativeView.clearFocus();
      if(this.tabview.nativeElement.android.getChildAt(1)){
        this.tabview.nativeElement.android.removeViewAt(1);
      }
    } else {
      this.tabview.nativeElement.ios.tabBar.hidden = true;
    }

    ad.dismissSoftInput();
  }

reopen issue because it important to fix
I think error come from GridLayout.java:229 and GridLayout.java:142 when page destroyed

xlmnxp on 2 May 2019

@xlmnxp
Check out the above-given solution ->

_make sure that you have added keyboard|smallestScreenSize|screenLayout|locale|uiMode options in the configChanges in your AndroidManifest.xml file._

_For example:_

android:configChanges="keyboard|keyboardHidden|orientation|screenSize|smallestScreenSize|screenLayout|locale|uiMode"

```

tsonevn on 6 May 2019

@tsonevn same thing
problem come in iOS too (take long time to back)

xlmnxp on 6 May 2019

I think problem not in split view
It's come when gridlayout removed from page ( when page destroy )

Hi @xlmnxp,
Can you send us a sample project and the exact steps, that you are using for recreating it?

tsonevn on 6 May 2019

@tsonevn I have private project, I invited you

xlmnxp on 10 May 2019

Hi @xlmnxp,
I just checked, but I haven't received any invitations yet in GitHub by you.

tsonevn on 10 May 2019

@tsonevn visit https://github.com/xlmnxp/sa.sy.yahmini/invitations

xlmnxp on 10 May 2019

Hi @xlmnxp,
I reviewed your project and noticed that you are using an old tns-core-modules, tns-ios, tns-android and nativescript-angular versions. Try to upgrade your project to the latest available versions(tns-core-modules v.5.3.2, tns-ios v.5.3.1, tns-android v. 5.3.1, nativescript-angular v.7.2.3, NativeScript CLI v.5.3.4) and check if you will be able to recreate the issue. For further help, you can review the upgrade instructions here.

Hi @xlmnxp,
Excuse me for the delay in reply.
I checked yesterday the project from the repository that you have attached, however, I am still not able to build the project for Android. For iOS I there is no problem with the Split view functionality. Check out the attached GIF.
Screencast 2019-05-28 at 1 52 29 PM

On that matter, I noticed that some of the plugins are not the latest version(e.g. nativescript-photoviewer, nativescript-web-image-cache, etc.) and this might be related to the crash. Try to upgrade also all plugins to their most recent version and check if the issue will be resolved.
