How can I create a object "android.content.ComponentName" in Unity3D with C#?
"android.content.ComponentName" need 2 args, but new AndroidJavaClass("android.content.ComponentName") can only one arg as class name.

I'd report that as a bug, it seems to be missing. You can bypass the limitation in writing a small plugin yourself:
