Saving .anim file at runtime

I am generating AnimationClip's in my project, and I want to reproduce them later. I know I can use:

 AssetDatabase.CreateAsset(yourAnimClip, "Assets/MyAnim.anim");
 AssetDatabase.SaveAssets();

The problem is this works only in Unity editor, not in the builds. Is there any way to save the AnimationClip besides figuring out the format of the .anim file? Maybe serializing it into a binary file?

Thank you
