private ArrayList<CustomGallery> getGalleryPhotos() {
        ArrayList<CustomGallery> galleryList = new ArrayList<CustomGallery>();

        try {
            final String[] columns = { MediaStore.Images.Media.DATA,
                    MediaStore.Images.Media._ID };
            final String orderBy = MediaStore.Images.Media._ID;

            @SuppressWarnings("deprecation")
            Cursor imagecursor = managedQuery(
                    MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns,
                    null, null, orderBy);
            if (imagecursor != null && imagecursor.getCount() > 0) {

                while (imagecursor.moveToNext()) {
                    CustomGallery item = new CustomGallery();

                    int dataColumnIndex = imagecursor
                            .getColumnIndex(MediaStore.Images.Media.DATA);

                    item.sdcardPath = imagecursor.getString(dataColumnIndex);
                    galleryList.add(item);
                }
            }
        }catch (Exception e) {
            e.printStackTrace();
        }

        // show newest photo at beginning of the list
        Collections.reverse(galleryList);

Answer 1

I think mediastore return wrong path.
Try check real file in path.

CustomGallery item = new CustomGallery();

                int dataColumnIndex = imagecursor
                        .getColumnIndex(MediaStore.Images.Media.DATA);

                item.sdcardPath = imagecursor.getString(dataColumnIndex);
                File temp = new File( item.sdcardPath );
                if( temp.exists() )
                     galleryList.add(item);

like this.
