Does AssetBundle on Android work well ?

Question

My development enviroment is Unity Pro 3.3, Android Pro, and Windows Xp.

I try to make my own avatar system with CharacterCustomization Sample. But on Android, I can't load data of assets via AssetBundles.

On Windows, I succeeded to load assets via AssetBundles.Load() with WWW class. But on Android, same program does not work well. I can't load data.

How do I load data of assets on Android ?

I've got the answer.

Points are these.

Use the option "BuildTarget.Android".
Describe the path with triple slash "file:///"

I did it with these processes.

Delete directories "Per Texture Materials", "assetbundles", and so on.
Use the option "BuildTarget.Android" to all "BuildPipeline.BuildAssetBundle".
Run these on Editor. Character Generator/Generate Materials Character Generator/Create Assetbundles Character Generator/Update Character Element Database
Copy Assetbundles database to Android device which like "/mnt/sdcard/assetbundles/"
Modify AssetbundleBaseURL. (the point was "

AssestBundles need to be made specifically for the target you want to use them on for it to work. It took a lot of swearing and head banging to figure this out. The docs should specify this. Once you make it for the android (or in this case, re-make them) it should work.

BuildPipeline.BuildAssetBundle(Selection.activeObject, selection, path, BuildAssetBundleOptions.CollectDependencies | BuildAssetBundleOptions.CompleteAssets, BuildTarget.Android);

notice the optional param BuildTarget.Android

Thanks, Victor! You saved the day with that comment! I don't know if I ever would have found that about the BuildTarget.Android if you didn't mention it. I made that one change and then it worked! Awesome!
