unity3d 獲取內存 android Used PssMemory
廢話不多直接上代碼

 public static int GetUsedPssMemory()
    {
        int memory = -1;
#if (UNITY_ANDROID && !UNITY_EDITOR) || ANDROID_CODE_VIEW
        try
        {
            using (AndroidJavaClass unityPlayer =  new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
            {
                using (AndroidJavaObject currentActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity"))
                {
                    using (AndroidJavaObject curApplication = currentActivity.Call<AndroidJavaObject>("getApplication"))
                    {
                        using (AndroidJavaObject am = curApplication.Call<AndroidJavaObject>("getSystemService", "activity"))
                        {
