玩家死亡時(shí),我已經(jīng)在游戲中捕獲了屏幕截圖.我正在按照以下代碼捕獲屏幕快照.

RenderTexture rt = new RenderTexture (800, 600, 24);    MainCamera.targetTexture = rt;    Texture2D texture = new Texture2D (800, 600, TextureFormat.RGB24, false);    MainCamera.Render ();    RenderTexture.active = rt;    texture.ReadPixels (new Rect (0, 0, 800, 600), 0, 0);    MainCamera.targetTexture = null;    RenderTexture.active = null;    Destroy (rt);    byte[] bytes = texture.EncodeToPNG ();    Directory.CreateDirectory (Application.persistentDataPath   "/GameOverScreenShot");    File.WriteAllBytes (Application.persistentDataPath   "/GameOverScreenShot"   "/DiedScreenShot.png", bytes);

我正在使用以下代碼保存屏幕截圖.

byte[] bytes = File.ReadAllBytes (Application.persistentDataPath  "/GameOverScreenShot"   "/BirdDiedScreenShot.png");Texture2D texture = new Texture2D (800, 600, TextureFormat.RGB24, false);RectOffset tempOffset = new RectOffset (5, 5, 5, 5);texture.filterMode = FilterMode.Trilinear;texture.LoadImage (bytes);Sprite sprite = Sprite.Create (texture, new Rect (0, 0, 800, 400), new Vector2 (0.5f, 0.0f), 2.0f);ScreenShot_Image.GetComponent<Image> ().sprite = sprite;

現(xiàn)在,我想在Android應(yīng)用程序上共享此屏幕截圖.根據(jù)我的研究,我已經(jīng)獲得了以下代碼,但是它返回的是空白圖像.

//instantiate the class IntentAndroidJavaClass intentClass = new AndroidJavaClass("android.content.Intent");//instantiate the object IntentAndroidJavaObject intentObject = new AndroidJavaObject("android.content.Intent");//call setAction setting ACTION_SEND as parameterintentObject.Call<AndroidJavaObject>("setAction", intentClass.GetStatic<string>("ACTION_SEND"));//instantiate the class UriAndroidJavaClass uriClass = new AndroidJavaClass("android.net.Uri");//instantiate the object Uri with the parse of the url's filestring destination = Application.persistentDataPath   "/GameOverScreenShot"   "/DiedScreenShot.png";AndroidJavaObject uriObject = uriClass.CallStatic<AndroidJavaObject>("parse","file://" destination);//call putExtra with the uri object of the fileintentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_STREAM"), uriObject);//set the type of fileintentObject.Call<AndroidJavaObject>("setType", "image/*");//instantiate the class UnityPlayerAndroidJavaClass unity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");//instantiate the object currentActivityAndroidJavaObject currentActivity = unity.GetStatic<AndroidJavaObject>("currentActivity");//call the activity with our IntentcurrentActivity.Call("startActivity", intentObject);

在這方面我應(yīng)該改變什么？請(qǐng)幫助,提前謝謝

解決方法:

只需調(diào)用takeScreenShotAndShare()即可截屏并共享它.如果您已經(jīng)有要共享的圖像,只需調(diào)用StartCoroutine(shareScreenshot(path));.并傳遞圖像的路徑/位置.這僅支持png圖像.要共享jpeg,請(qǐng)更改

intentObject.Call<AndroidJavaObject>("setType", "image/png");

至

intentObject.Call<AndroidJavaObject>("setType", "image/jpeg");

整個(gè)代碼：

void takeScreenShotAndShare(){    StartCoroutine(takeScreenshotAndSave());}private IEnumerator takeScreenshotAndSave(){    string path = "";    yield return new WaitForEndOfFrame();    Texture2D screenImage = new Texture2D(Screen.width, Screen.height);    //Get Image from screen    screenImage.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);    screenImage.Apply();    //Convert to png    byte[] imageBytes = screenImage.EncodeToPNG();    System.IO.Directory.CreateDirectory(Application.persistentDataPath   "/GameOverScreenShot");    path = Application.persistentDataPath   "/GameOverScreenShot"   "/DiedScreenShot.png";    System.IO.File.WriteAllBytes(path, imageBytes);    StartCoroutine(shareScreenshot(path));}private IEnumerator shareScreenshot(string destination){    string ShareSubject = "Picture Share";    string shareLink = "Test Link"   "\nhttps://stackoverflow.com/questions/36512784/share-image-on-android-application-from-unity-game";    string textToShare = "Text To share";    Debug.Log(destination);    if (!Application.isEditor)    {        AndroidJavaClass intentClass = new AndroidJavaClass("android.content.Intent");        AndroidJavaObject intentObject = new AndroidJavaObject("android.content.Intent");        intentObject.Call<AndroidJavaObject>("setAction", intentClass.GetStatic<string>("ACTION_SEND"));        AndroidJavaClass uriClass = new AndroidJavaClass("android.net.Uri");        AndroidJavaObject uriObject = uriClass.CallStatic<AndroidJavaObject>("parse", "file://"   destination);        intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_STREAM"), uriObject);        intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_TEXT"), textToShare   shareLink);        intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_SUBJECT"), ShareSubject);        intentObject.Call<AndroidJavaObject>("setType", "image/png");        AndroidJavaClass unity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");        AndroidJavaObject currentActivity = unity.GetStatic<AndroidJavaObject>("currentActivity");        currentActivity.Call("startActivity", intentObject);    }    yield return null;}
