 public sealed class AdUnionContext : MonoBehaviour
    {
 
        private AndroidJavaObject currentActivity;

        private static readonly AdUnionContext _AdUnionContext = new AdUnionContext();

        /*
         * 获取当前实例

        public AndroidJavaObject GetActivity()
        {
            if (null == currentActivity)

        /*
         * 运行在主UI线程       
         */       
        public void RunOnUIThread(AndroidJavaRunnable runnable)
