I have tried this to get directories and load images from them but it is very slow to load images and when camera is selected it crashed after some time...

So I am loading all images from the gallery it is working fine but MediaStore.MediaColumns.DATA is deprecated. I am unable to find an example that using the latest method to perform this task without MediaStore.MediaColumns.DATA

I'm trying to do a simple thing and its get all images from the external storage into recycle view and display them.
My problem is that for some reason i recieve null and i dont know why.
I successfully getting all the images into array list of string.
And then on the Reycleview i'm getting error of null exception.
Cant find what im doing wrong.
The log shows me that the error comes from the Recycler.From the method "onBindViewHolder" (i also mentioned this line).
It craches holder.imgView.setImageURI(imageUri); - still cant understand why,
even though i checked that its not null.

What is null is this in your ImageViewHolder ImageView imgView;
You're using
imgView = (ImageView)findViewById(R.id.imageView);
But look that findViewById is finding a view in your activity, and not in your RecyclerView ViewHolder, precisely in your image_item.xml root layout.
So, just use findViewById in that view:
public ImageViewHolder(View itemView){
super(itemView);
imgView = (ImageView) itemView.findViewById(R.id.imageView);
}
This is my first app on Android and I am using the Universal Image Loader Library to load images into a GridView.
The problem I am having is
FileNotFoundException: No entry for content://media/external/images/thumbnails/...(all thumbnails )
The thumbnails are not loaded in the GridView, but when I tap on a gridItem, the Intent is started and an imageId is passed to the next activity.
Here is the code I am using (based on the Sample example at UIL( github)
public class ImageGridFragment extends AbsListViewBaseFragment {

Any help with understanding what I am doing wrong and how to fix it would be greatly appreciated.
SOLVED!
I changed this line
Uri imageURI = Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, "" + imageID);
to
Uri imageURI = Uri.withAppendedPath(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "" + imageID);
If your path having filename with extension like .png, .jpg or any than it is file path, in such case you have to add string as
"file://"+ filename.
And if your path not having any extension and not web url, so it is content uri, here you have to add
"content://"+filename.

I've been trying to create multiple image chooser, everything works fine, but the grid scroll is very lazy and slow, I've been tried to use different libraries for image loading in getView() (Picasso,aquery..)
but its no difference ,even with asynctask, that's my code:

}
As you said you have tried picasso library it should work
Just try once again using picassso like this Async task and all is not required
Just create a simple adapter and load images.
public class GridViewDynamicAdapter extends BaseDynamicGridAdapter {
ImageDetails details;
public static List<ImageDetails> list;
public GridViewDynamicAdapter(Context context, List<ImageDetails> items,
int columnCount) {
super(context, items, columnCount);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
CheeseViewHolder holder;
if (convertView == null) {
convertView = LayoutInflater.from(getContext()).inflate(
R.layout.item_grid, null);
holder = new CheeseViewHolder(convertView);
convertView.setTag(holder);
} else {
holder = (CheeseViewHolder) convertView.getTag();
}
if (position == getCount() - 1) {
ImageApplication.fromRecorderPaths = (List<ImageDetails>) getItems();
}
details = (ImageDetails) getItem(position);
// Log.d("Setting=", details.path);
holder.build(getContext(), details.path);
return convertView;
}
private class CheeseViewHolder {
private ImageView image;
private CheeseViewHolder(View view) {
image = (ImageView) view.findViewById(R.id.item_img);
}
void build(final Context context, String title) {
Picasso.with(context).load(new File(title)).centerCrop()
.resize(150, 150).error(R.drawable.ic_launcher).into(image);
}
}
}

How to get thumbnails from a specific folder in sd card. I am using this tutorial http://gypsynight.wordpress.com/2012/02/17/how-to-show-all-video-file-stored-in-your-sd-card-in-a-listview/
It can be done easily this way:
int videoId = videoCursor.getInt(videoCursor.getColumnIndexOrThrow(MediaStore.Video.Media._ID));
ContentResolver cr = getContentResolver();
BitmapFactory.Options options=new BitmapFactory.Options();
options.inSampleSize = 1;
Bitmap curThumb = MediaStore.Video.Thumbnails.getThumbnail(cr, videoId, MediaStore.Video.Thumbnails.MICRO_KIND, options);
thumbImage.setImageBitmap(curThumb);
