"using Android" doesn't recognizable on Unity

[Astroni]

Hello, it’s me again. As last time I write something with Unity for Android. Now the problem is, that I want to use functions tipical for Android (not only for C#, like last time) and I discover that I can’t. Though I’ve installed Android SDK and I can build project for this device, something is wrong, cause when I try to write using Android.content or something like that, editor and compilator does not recognize it, the type or namespace name ‘Android’ could not be found. As I said, I have SDK installed (Android 4.2 precisely), I have Unity3D able to create Android apps (what’s mean that the program know where the SDK is), and I don’t know what to do else. I supose I could do something in MonoDevelop in Tools > Add-in Manager and Install from file, but… I don’t know what exactly should I install… It looks like I need some packages. But where get it?

I’ve, like always, searched for answear in Google, but there is information just about Java or about MonoDevelop without Unity (as here, where I would had to install MonoDevelop from begin). Indeed I start to doubt, is actually connection Unity+Android+C# realizable?

Somebody know what to do? I’m too confused already. I hope I didn’t forget about something important.

Thanx

With Unity you don’t do native Android programming. Unity uses Mono as “scripting language”. The only namespace that comes with Unity is the UnityEngine namespace. You can use other .NET stuff as well, but nothing that doesn’t exist in the linked .NET libraries.

You should use mainly what Unity provides via it’s own API. You can write native code plugins in Java (yes Java, not JavaScript) for example and use those in your C# scripts.
