问题

I'm trying to build a soundboard app. I have lots of sounds to deploy so I decided to use Play Asset Delivery. I followed the instructions in the Google's guide.

1. I created an asset pack folder in the top level and named it sounds. This is how my project looks

   Project structure:
   

   This is the build.gradle file in the sounds directory:

   apply plugin: 'com.android.asset-pack'
   assetPack {
       packName = "sounds" // Directory name for the asset pack
       dynamicDelivery {
           deliveryType = "[install-time]"
       }
   }

2. Updated my app build.gradle file:

   android {
       ...
       assetPacks = [":sounds"]
   }

   and my settings.gradle file:

   include ':app'
   include ':sounds'

3. Placed the assets in the sounds/src/main/assets.

When I try to build the bundle, I keep getting this error:

Gradle Error:

This is the Manifest in the sounds folder:

Manifest with errors:

I tried cleaning the project, invalidating caches, and restarting, but nothing seems to work.

apply plugin: 'com.android.asset-pack'
assetPack {
packName = "sounds" // Directory name for the asset pack
dynamicDelivery {
    deliveryType = "[install-time]"
}
}

include ':app'
include ':sounds'

After spending so many hours I managed to build the bundle successfully.

Simply remove brackets from your asset folder's build.gradle file

deliveryType = "install-time"

This is Google's example code for Play Asset Delivery

// In the asset pack's build.gradle file:
apply plugin: 'com.android.asset-pack'

assetPack {
packName = "asset-pack-name" // Directory name for the asset pack
dynamicDelivery {
deliveryType = "[ install-time | fast-follow | on-demand ]"
}
}

I thought deliveryType = "[install-time]" would be the correct syntax. After comparing my asset pack manifest with a dynamic feature's manifest I realized gradle produces a wrong dist attribute.

This is what i got for writing deliveryType with brackets

dist:[install-time]/

This is the correct syntax in the dynamic feature's manifest

<dist:on-demand />

Removing brackets did the trick. Hope it helps someone.

deliveryType = "install-time"

// In the asset pack’s build.gradle file:
apply plugin: 'com.android.asset-pack'
assetPack {
    packName = "asset-pack-name" // Directory name for the asset pack
    dynamicDelivery {
        deliveryType = "[ install-time | fast-follow | on-demand ]"
    }
}

<dist:[install-time]/>

<dist:on-demand />
