如何在Android(kotlin)中访问资产打包数据 [英] How to access assets-pack data in Android (kotlin)

问题描述

我使用资产打包库在Android kotlin应用程序中打包了一些资产:

现在根据文档( https://developer.android.com/guide/playcore/asset-delivery/integrate-java )，我可以像这样访问资产:

  import android.content.res.AssetManager;...上下文context = createPackageContext("com.example.app"，0);AssetManager assetManager = context.getAssets();InputStream是= assetManager.open("asset-name")； 

我将软件包名称更改为我的软件包名称.但是资产名称是什么?！不是我的 models 资产文件夹中文件的名称.我试过了我想到的是 assetManager.list(p)和 p ，但是我找不到资产的存储位置.

对于 p =''， assetManager.list(p)的结果为

 <代码> hw_pc_white_apps.xmlhw_pc_white_apps_pad.xml图片Permission_grant_policy.xmlPermission_grant_policy_oversea.xmlPFWsfpconfig.jsonukeyapp.xml水碎片水网页套件wifi_policy.xmlwifipro_regexlist.xml 

这对我也没有意义.如何从资产包访问资产?

解决方案

好，我找到了解决方案:Android Studio默认不提供资产包，需要在 Run->下调整配置.编辑配置->从应用程序包中交付APK ( https://developer.android.com/指南/应用程序捆绑/测试)以交付资产和应用程序.

现在可以像主应用程序的资产一样访问这些资产.

I packed some assets in my Android kotlin app using the asset-pack library: https://developer.android.com/guide/app-bundle/asset-delivery/build-native-java

Not I should be able to access the assets using the AssetManager via context.assets. However, I have no clue what the correct path is.

My assets pack is called models and correctly created in the root folder of the .aab file, so I guess it is also installed correctly.

Now according to the documentation (https://developer.android.com/guide/playcore/asset-delivery/integrate-java) I can access the assets like this:

import android.content.res.AssetManager;
...
Context context = createPackageContext("com.example.app", 0);
AssetManager assetManager = context.getAssets();
InputStream is = assetManager.open("asset-name");

where I chane the package name to my package name. But what is the asset name?!? It's not the name of the files in my models asset folder. I tried assetManager.list(p) with p as anything I could think of, but I could not find where my assets are stored.

For p='' the result of assetManager.list(p) is

 hw_pc_white_apps.xml
    hw_pc_white_apps_pad.xml
    images
    permission_grant_policy.xml
    permission_grant_policy_oversea.xml
    pfw
    sfpconfig.json
    ukeyapp.xml
    water.frag
    water.vert
    webkit
    wifi_policy.xml
    wifipro_regexlist.xml

which also makes no sense to me. How can I access assets from asset packs?

解决方案

Ok, I found the solution: the Android Studio does not deliver the asset packs by default, the configuration needs to be adjusted under Run -> Edit configuration -> Deliver APK from app bundle (https://developer.android.com/guide/app-bundle/test) to deliver assets and the app.

Now the assets are accessible as if they were assets of the main app.
