Hi everyone!

I’ve been looking for answers everywhere but I couldn’t find it.

I’m trying to take a screenshot and upload it to apps. Here’s my code

public void TakeScreenShot(GameObject a){
		Vector3 ScreenShotPos = new Vector3(1.7f,-6.95f,0f);
		ssName = "PIXMA.png";

		if (a != null)
			CharaForScreenShot = a;

		temp = GameObject.Instantiate(CharaForScreenShot,ScreenShotPos,CharaForScreenShot.transform.rotation) as GameObject;
	
		path = Path.Combine(Application.persistentDataPath,ssName);
		print (path);

		//delay for screenshot
		StartCoroutine(TakeScreenShot());

	}

	IEnumerator TakeScreenShot() {
		// We should only read the screen buffer after rendering is complete
		yield return new WaitForEndOfFrame();
		
		// Create a texture the size of the screen, RGB24 format
		int width = Screen.width;
		int height = Screen.height;
		Texture2D tex = new Texture2D(width, height, TextureFormat.RGB24, false);
		
		// Read screen contents into the texture
		tex.ReadPixels(new Rect(0, 0, width, height), 0, 0);
		tex.Apply();
		
		// Encode texture into PNG
		byte[] bytes = tex.EncodeToPNG();
		Object.Destroy(tex);

		// For testing purposes, also write to a file in the project folder
		File.WriteAllBytes(path, bytes);
		
		StartCoroutine(wait(3));
		
	}

	private IEnumerator wait(int waitTime){
		yield return new WaitForSeconds(waitTime);

		if( File.Exists(path) ) {//file exist
			WWW loadedImage = new WWW("file://"+path);
			if (temp != null) Destroy(temp);
			SSImg.texture = loadedImage.texture;
			CollectionSceneHandler.instance.waitToShare(path);
			CollectionSceneHandler.instance.DisableScreenShotCamera();


		}else{//file doesn't exist
			print ("file not exist");
		}

and I got codes below from Share an image calling external apps on Unity for Andorid

IEnumerator ShareToInstalledApps(string path){
		yield return new WaitForSeconds(3);

		//instantiate the class Intent
		AndroidJavaClass intentClass = new AndroidJavaClass("android.content.Intent");
		
		//instantiate the object Intent
		AndroidJavaObject intentObject = new AndroidJavaObject("android.content.Intent");
		
		//call setAction setting ACTION_SEND as parameter
		intentObject.Call<AndroidJavaObject>("setAction", intentClass.GetStatic<string>("ACTION_SEND"));
		
		//instantiate the class Uri
		AndroidJavaClass uriClass = new AndroidJavaClass("android.net.Uri");
		
		//instantiate the object Uri with the parse of the url's file
		AndroidJavaObject uriObject = uriClass.CallStatic<AndroidJavaObject>("parse","file://"+path);
		
		//call putExtra with the uri object of the file
		intentObject.Call<AndroidJavaObject>("putExtra", intentClass.GetStatic<string>("EXTRA_STREAM"), uriObject);
		
		//set the type of file
		intentObject.Call<AndroidJavaObject>("setType", "image/jpeg");
		
		//instantiate the class UnityPlayer
		AndroidJavaClass unity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
		
		//instantiate the object currentActivity
		AndroidJavaObject currentActivity = unity.GetStatic<AndroidJavaObject>("currentActivity");
		
		//call the activity with our Intent
		currentActivity.Call("startActivity", intentObject);
	}

the screenshot work well,. The Image shows when I call it using WWW.

The problem is whenever I try to share the image. it always gets an error.

Please help!

DO NOT FORGET to Grant the Writing Access to External (SDCard) in PlayerSettings (Other Settings), otherwise you won’t be able to share pictures.
