Unity 生成 Android App Bundle(aab) （三）
aab命令手机安装
aab转apks
C:/g/Java/jdk1.8.0_231\bin\java.exe -jar "插件下载地址\UnityProj\Assets\GooglePlayPlugins\com.google.android.appbundle\Editor\Tools\bundletool-all.jar" build-apks --bundle="D:\aab.aab" --output="D:\aab.apks" --ks=F:\keyStore\keystore.keystore --ks-pass=pass:pass --ks-key-alias=alias --mode=persistent --local-testing
apks安装
C:/g/Java/jdk1.8.0_231\bin\java.exe -jar "插件下载地址\UnityProj\Assets\GooglePlayPlugins\com.google.android.appbundle\Editor\Tools\bundletool-all.jar" install-apks --adb="D:\android-sdk-windows\platform-tools\adb.exe" --apks="D:\aab.apks"
AssetDeliveryErrorCode错误返回
AssetBundles 流程
1、用PlayAssetDelivery.IsDownloaded判断是否下载完毕
2、下载完毕的，加载assetbundle
PlayAssetBundleRequest bundleRequest = PlayAssetDelivery.RetrieveAssetBundleAsync(assetBundleName);
//这里会调用 ProcessPackStateUpdate，就是一直报错的地方，资源加载中(这里应该是加载资源到指定位置（资产包正在下载并转移到应用程序的存储），因为例子中有 installtime，这个没有触发ProcessPackStateUpdate，fastfollow触发了ProcessPackStateUpdate)
while (!bundleRequest.IsDone)
{
yield return null;
}
Debug.Log($"LoadAssetBundlesFromAssetPacks assetBundleName:{assetBundleName} bundleRequest.Error:{bundleRequest.Error.ToString()} bundleRequest.Status:{bundleRequest.Status.ToString()}");
if (bundleRequest.Error == AssetDeliveryErrorCode.NoError)
{
gameAssetManager.AddAssetBundle(assetBundleName,
bundleRequest.AssetBundle);
3、没有下载的手动下载
先获得包大小 PlayAssetDelivery.GetDownloadSize(assetPackName);
请求下载
PlayAssetDelivery.RetrieveAssetBundleAsync(assetPackName);
触发下载进度值 ProcessPackStateUpdate，这里会修改assetBundleRequest.DownloadProgress
更新下载进度 assetBundleRequest.DownloadProgress
下载完成清除 gameAssetPack.FinishBundleDownload()
AssetPack 流程
1、是否下载完毕 PlayAssetDelivery.IsDownloaded
2、下载完毕的，加载
PlayAssetDelivery.RetrieveAssetPackAsync(assetPackName);
while (!packRequest.IsDone)
{
yield return null;
}
if (packRequest.Error == AssetDeliveryErrorCode.NoError)
{
3、没有下载的手动下载
先获得包大小 PlayAssetDelivery.GetDownloadSize(assetPackName);
请求下载
PlayAssetDelivery.RetrieveAssetPackAsync(assetPackName);
这里需要检测下载状态，是否下载异常和蜂窝网络assetPackRequest.Status
触发下载进度值 ProcessPackStateUpdate，这里会修改 assetPackRequest.DownloadProgress
更新下载进度 assetPackRequest.DownloadProgress
下载完成清除 gameAssetPack.FinishPackDownload();
