Hey all,

Every time I open a newly built Android app there's a ~10 second delay before I see my app. You can see this on https://github.com/tjvantoll/grocery-list—just run `tns run android` or `tns run android --emulator`.

I see the same delay when I deploy the sample app from the NativeScript CLI, and I haven't messed with any config files. My gut tells me this is related to the splash screen (or lack thereof), but I'm not quite sure. Any ideas?

Thanks,
TJ

Hi TJ,

At present the very first run of every NativeScript for Android application is slow. This is due the technical limitations of the current implementation.

On the very first run we extract (unzip) a lot of files from the *.apk file and it takes time. On ART enabled devices there is yet another step (more specifically AOT compilation) that slows down the application.

The good news is that we are working on another approach which will reduce the initial start-up time. We expect it will be integrated for the first NS Beta release in the first week of February.

Regards,
Mihail
