Sample code at app-bundle-samples/PlayAssetDelivery/NativeSample/ not generating all standalone apks

I am trying to use the sample code located here - https://github.com/android/app-bundle-samples/tree/main/PlayAssetDelivery/NativeSample to get an understanding of App Bundles.

According to the documentation when the minSDK Version is less than 21, the Bundle shall generate standalone apks for every ABI-DPI combination. In this case when we are generating the standalone apks using the following command -

```
Bundletool build-apks --bundle=Teapot-release.aab --output=output.apks
```

**Bundletool Version - 1.11.0**

The Standalones folder just generates a single standalone apk.

On debugging further it seems like the bundle config has this set for Standalone Dimensions -

```
"standaloneConfig": {
"splitDimension": [{
"value": "ABI",
"negate": true
}, {
"value": "SCREEN_DENSITY",
"negate": true
}, {
"value": "LANGUAGE",
"negate": true
}, {
"value": "TEXTURE_COMPRESSION_FORMAT",
"negate": true
}],
"strip64BitLibraries": true
}
},
```

However when I set the minSdk value >=21, in that case the StandaloneConfig is empty. I donot see a place where these standalone configuration is being set. Am I missing something over here?

Inizia con app-bundle-samples/PlayAssetDelivery/NativeSample/ e riproduci l’output usando Bundletool 1.11.0 con il comando documentato. Confronta gli APK standalone generati e standaloneConfig per valori di minSdk inferiori a 21 e di almeno 21; il lavoro è completato quando si determina se l’esempio o la configurazione spiegano le combinazioni ABI-DPI mancanti e si documenta o corregge tale comportamento.
