This was fixed in the following commit d20a991.

The reason this didn't work for you is because you need to include the period . in the file extension.
So .tflite rather than just tflite. Doing so means the resulting asset will be stored as you can see from the output below.

 unzip -lv obj/Debug/android/bin/packaged_resources | grep assets
 4183312  Stored  4183312   0% 01-01-1980 01:00 1313ae97  assets/detect.tflite

[dellis1972]

Note this is just the way aapt2 expects the parameter. I'll look at adding a fix which will prepend the . if it's not present.

[matheusouz]

I tried the two ways and didn't work. But is good know it is already fixed.

Thanks.

In case it might be useful to mention, the release status of the original fix from d20a991 can be tracked in the corresponding issue #3675.

In short, with Visual Studio 2019 version 16.4 (currently in Preview), Uncompressed resource extensions will work successfully with AAPT2 as long as the listed file extensions start with ..
