This maps to this Google package:

android-libraries/config.json

Lines 5058 to 5067 in d3b5c00

	{
	"groupId": "org.tensorflow",
	"artifactId": "tensorflow-lite",
	"version": "2.16.1",
	"nugetVersion": "2.16.1.7",
	"nugetId": "Xamarin.TensorFlow.Lite",
	"frozen": true,
	"type": "androidlibrary",
	"mavenRepositoryType": "MavenCentral"
	},

There is a newer version:

• https://mvnrepository.com/artifact/org.tensorflow/tensorflow-lite

@moljac do you know why this particular one is "frozen"? Was there an issue updating it?

OK.

1. TL&DR;

TensorFlow is deprecated replacement is Xamarin.Google.AI.Edge.LiteRT
https://www.nuget.org/packages?q=litert

2. deeper

   tensorflow-lite pom.xml should REDIRECT to LiteRT, but binderator does not have that support. I did add it to some of my APIs nugets and I was able to use them locally, but never had a chance to add it to Binderator.

Oh yes!! It is RELOCATION

[deepamhatre]

What should I use now? Keep using the version 2.16.1.7 for Xamarin.TensorFlow.Lite? Or should I use the package Xamarin.Google.AI.Edge.LiteRT?
Are there any code changes required to use the new package Xamarin.Google.AI.Edge.LiteRT?

No. It is deprecated and replaced with Xamarin.Google.AI.Edge.LiteRT.*

Or should I use the package Xamarin.Google.AI.Edge.LiteRT?

Correct.

Are there any code changes required to use the new package Xamarin.Google.AI.Edge.LiteRT?

I don't think so. Or maybe minimal. not sure 100%

[deepamhatre]

@moljac Thanks for this. I have managed to get rid of the Android 16 KB page sizes warning by using the new package 'Xamarin.Google.AI.Edge.LiteRT (1.4.0.1)'

No code changes are required

[jonathanpeppers]

Thanks, sounds like that is the solution!
