getting `Unable to destroy activity: Cannot read property 'getIntent' of undefined`

[Liooo]

I installed my app on a device, opened the app which triggers location tracking, leave it for like a day, and the app crashed when I opened the app again. I haven't found the exact way to reproduce it so far, but the error content seems that it's coming from the plugin and that it's possibly enough to identify the reason. Sorry for the lack of the information.

I am also getting this on nativescript 4.1, tns-android 4.1.2. For me, I can only reproduce when I modify the display size under the android settings. Changing this from largest to default and back (and focusing the app each time) will eventually trigger this. Have not been able to reproduce otherwise.

[christocracy]

I have a significant refactor coming tomorrow built against latest nativescript.

[Liooo]

@christocracy is it done?

[christocracy]

Working on it right now. I'm going to do a final field-test soon with my batch of test-devices.

[christocracy]

1.9.0-beta.3 released. Be sure to do this

[Liooo]

awesome I'll check it, thanks!

[bradseefeld]

FYI, I have not seen this in our production build since upgrading to beta3.

[Liooo]

@christocracy been running the app for a few weeks straight but still working without any problems, thanks 👍

[christocracy]

Glad it's working. Thanks for the update.
