Unity3D从Android里拿包名（Bundle Identifier）

public class BundleIdentifierTest : MonoBehaviour {

// Use this for initialization
void Start () {
using (var unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
{
using (AndroidJavaObject activity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity"))
{
using (AndroidJavaObject assetManager = activity.Call<AndroidJavaObject>("getApplicationContext"))
{
text = assetManager.Call<string>("getPackageName");
}
}
}
}

string text;
void OnGUI()
{
GUILayout.Label(text);
}
}

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

String e = getApplicationContext().getPackageName();
}
