unity3d android 獲取是否安裝app
廢話不多直接上代碼

    public static bool IsInstallApp(string packageAndroidName)
    {
#if (UNITY_ANDROID && !UNITY_EDITOR) || ANDROID_CODE_VIEW
            try
            {

                {
                    using (AndroidJavaObject currentActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity"))
                    {
                        using (AndroidJavaObject packageManager = currentActivity.Call<AndroidJavaObject>("getPackageManager"))
                        {
                            try
