Images not reflected in the gallery after saved

Question

 if (action.equals("saveToGallery")) {

                        JSONObject obj = args.getJSONObject(0);
                        String imageSource = obj.has("imageSrc") ? obj.getString("imageSrc") : null;
                        String imageName = obj.has("imageName") ? obj.getString("imageName") : null;
                        String savedImgSrc = saveImageToGallery(imageSource, imageName);
                        Log.v("SAve To Gallery ", "saved file url:  " + savedImgSrc);

                        return new PluginResult(PluginResult.Status.OK);
                    }
                    return new PluginResult(PluginResult.Status.INVALID_ACTION);
                } catch (JSONException e) {
                    e.printStackTrace();
                    return new PluginResult(PluginResult.Status.JSON_EXCEPTION);
                }

public String saveImageToGallery(String imgSrc, String imgName) {
        Log.v("Save To Gallery ", "image SRc:  " + imgSrc + " , image Name:"
                + imgName);

        Context ctx = this.ctx;
        AssetManager assmgr = ctx.getAssets();
        File tempDir = new File("/sdcard/HarmonyDayApp/wallpapers/");
        tempDir.mkdirs();
        File file = new File(tempDir, imgName);
        try {
            InputStream is = null;
            is = assmgr.open("www/" + imgSrc);
            OutputStream os = new FileOutputStream(file);
            byte[] data = new byte[is.available()];
            is.read(data);
            os.write(data);
            sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://"+Environment.getExternalStorageDirectory())));
            is.close();
            os.close();
        } catch (IOException ex) {
            Log.w("ExternalStorage", "Error writing " + file, ex);
        }
        return file.getAbsolutePath();

    }

This is the code I am using to save the image to the device gallery. However, after the image is saved, if i check the gallery imeediately, the image is not there. It comes when i reload the application, or the gallery after sometime. Any suggestion to this problem will be helpful.

you need to scan media manually, after your image has been saved, by following code:

 // Tell the media scanner about the new file so that it is
    // immediately available to the user.
    MediaScannerConnection.scanFile(this,new String[] { file.toString() }, null,
    new MediaScannerConnection.OnScanCompletedListener() {
    public void onScanCompleted(String path, Uri uri) {
    Log.i("ExternalStorage", "Scanned " + path + ":");
    Log.i("ExternalStorage", "-> uri=" + uri);
    }
    });

it says scanFile cannot be used for WebIntent Plugin of mine. — Khush, Jan 23 '12 at 08:16

Try this:

After adding your image in gallery you need to broadcast

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse(“file://”+
 Environment.getExternalStorageDirectory())));

Hopefully it will work for you. :)

I need to create a sendBroadcat mehtod for that. Could you kindly tell me what needs to be the content of the method and where should i place it? – Khush Jan 23 '12 at 08:16
After saving the image in gallery ,only need to paste this: Log.v("SAve To Gallery ", "saved file url: " + savedImgSrc); sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse(“file://”+ Environment.getExternalStorageDirectory()))); thats it. no need to create anycbroadcast. – Andy Jan 23 '12 at 09:00
But it gives an error sayin "Sendbroadcast is not a function. create one." – Khush Jan 23 '12 at 09:28
