I have crash reports from users. I have not been able to reproduce, but I can see in the code how the problem can occur.
Is there any code involved?
See file: @nativescript-community/ui-material-core-tabs/tab-navigation/index.android.js
'createNativeView' calls 'handleTabStripChanged'. Crash occurs via 'handleTabStripChanged'... nativeView.removeView(this.mTabsBar);
'nativeView' was just created by caller, therefore it does not contain 'mTabsBar'. So if 'createNativeView' is ever called when 'mTabsBar' exists, then I expect it will crash. My hack-fix is to set "this.mTabsBar = null;" in 'createNativeView', prior to calling 'handleTabStripChanged', but I have not been able to verify.
