Out of Memory when running CameraXTfLite for 25 minutes

I'm tring to write an App similar to the TfLite example but am running into out of memory problems. I see the same or similar problems with the TfLite sample:

After ~ 25 minutes I get the following creash on my Moto G5 (Another One plus device appears unaffected but maybe this has more memory?)

I've tried profiling but this shows nothing odd to me

```

WIth my App it fails in a similar manner after 20 minutes or so e.g:

```

```
The memory heap debug reports suggest that there is plenty of memory available. Maybe it becomes too fragmented?

Any ideas suggestions?

Inizia riproducendo l’esempio CameraXTfLite sul Moto G5 e analizza il percorso CameraDetector$getAnalyzer insieme ai log segnalati di heap, GPU e allocazione dei thread. Verifica se le risorse della fotocamera, dell’analyzer o delle immagini si accumulano durante un’esecuzione di 20–25 minuti; il lavoro è completato quando l’esempio non raggiunge più il crash Out-of-Memory segnalato sul dispositivo interessato.
