Let me explain you what's happening, when running the app, the debug session is starting, everything is okay, then, at the moment when the app is loading and opening on the android emulator, it's freezing and closing directly. Then you have : 'lost connection to device'

Hi @Tanelo,

I have found the reason for your issue.

Are you running the example on an emulator? It seems like this package is no longer compatible on android emulators.

Do you have an android device by any chance? if yes, can you run it on that device in the meantime?

When i have time, I will provide an update.

Tanelo commented 3 years ago

Hi @Caldarie, i will ! Thanks. That would be dope if you'd provide an update !

cmalbuquerque commented 3 years ago

I had the same problem before I run in a physical device and after some research I think it is an architecture incompatibility with your emulator.

Caldarie commented 3 years ago

@cmalbuquerque Many thanks for letting me know.

Yeah, it may seem so. Technology does change fast. Haha!

pierremotard commented 3 years ago

Even on physical device I still have this error (both on simulator and on device): error: package org.tensorflow.lite does not exist Even though it works on ios device now.

Caldarie commented 3 years ago

@pierremotard can you provide a full log please?

Here is the full log, running on Samsung S10

@pierremotard When you run the example given in this repository, do you still get the same error?
