input tensor 0 is missing TensorMetadata

Question

This article shows how to add meta_data into a tflite model before running in Android. However, it only shows example for Image classification. I am trying to add meta data for Audio classification. How can I get guide.

I am getting error in Android when running a model.tflite which has no meta data.

Error getting native address of native library: task_audio_jni
java.lang.IllegalArgumentException: Error occurred when initializing AudioClassifier: input tensor 0 is missing TensorMetadata.
