getTheme not working on app startup

[erjdriver]

Using the latest release 2.3.3 of theme and NS.

On Android platform, Theme.getMode() doesn't work on app startup.

I've got my phone Display settings in Dark theme.

When the app starts up (before run) - I do a getMode() and it returns ns-light.

Shouldn't it return ns-dark.

The app does start up in Dark theme.

This seems to be related to issue #232

I'm also intercepting systemAppearanceChangedEvent callback - when this event is called has the app already changed to the new theme or do I have to call Theme.setMode().

Thank you.

Weird bug!

This is using NS 6.5 w/ latest ns-theme plugin and Android platform.

Create a new project using

tns create testproject --tsc template

run on device and toggle the device theme - works fine.

Now go to app.ts and add the following line before application.run

Theme.getMode() along with the import.

The colors no longer change on device theme toggle.

Can you check if this works with the latest @next version?

No.

Returns the wrong result and now crashes.
