    I made a simple app for android devices that uses mobile's camera to take a photo and save it in internal storage folder /mnt/sdcard/DCIM/Camerizeman/

    Photos are saved correctly but the problem that i am faceing is that i can't see the photos from mobile's gallery. I can see them correctly if i use a file manager or reboot me device. i am searchig 10 days now and the problem is that i have to refresh the gallery after saving the image.

    I didn't found any working solution.

    my code is bellow:

    Camera mainCamera;
    RenderTexture renderTex;
    Texture2D screenshot;
    Texture2D LoadScreenshot;
    int width =Screen.width; // for Taking Picture
    int height =Screen.height; // for Taking Picture
    string fileName;
    string myScreenshotLocation;
    string screenShotName ="MyImage_AR_"+System.DateTime.Now.ToString("yyyy-MM-dd-HHmmss")+".png";

    publicvoidSnapshot(){
    StartCoroutine(CaptureScreen());
    }

    publicIEnumeratorCaptureScreen(){
    yield returnnull;
    UI//GameObject.FindGameObjectWithTag("Snapshoot").SetActive(false);
    yield returnnewWaitForEndOfFrame();

    if(Screen.orientation ==ScreenOrientation.Portrait||Screen.orientation ==ScreenOrientation.PortraitUpsideDown){
    mainCamera =Camera.main.GetComponent<Camera>();// for Taking Picture
    renderTex =newRenderTexture(width, height,24);
    mainCamera.targetTexture = renderTex;RenderTexture.active = renderTex;
    mainCamera.Render();
    screenshot =newTexture2D(width, height,TextureFormat.RGB24,false);
    screenshot.ReadPixels(newRect(0,0, width, height),0,0);
    screenshot.Apply();//falseRenderTexture.active =null;
    mainCamera.targetTexture =null;
    }

    if(Screen.orientation ==ScreenOrientation.LandscapeLeft||Screen.orientation ==ScreenOrientation.LandscapeRight){
    mainCamera =Camera.main.GetComponent<Camera>();// for Taking Picture
    renderTex =newRenderTexture(height, width,24);
    mainCamera.targetTexture = renderTex;RenderTexture.active = renderTex;
    mainCamera.Render();
    screenshot =newTexture2D(height, width,TextureFormat.RGB24,false);
    screenshot.ReadPixels(newRect(0,0, height, width),0,0);
    screenshot.Apply();//falseRenderTexture.active =null;
    mainCamera.targetTexture =null;
    }

    myScreenshotLocation = myFolderLocation + screenShotName;File.WriteAllBytes(myFolderLocation + screenShotName, screenshot.EncodeToPNG());}

    In Android , you have to write native code to refresh gallery, otherwise not possible.
