private class ListViewContactsLoader extends AsyncTask<Void, Void, Cursor>{

    @Override
    protected Cursor doInBackground(Void... params) {
        Uri contactsUri = ContactsContract.Contacts.CONTENT_URI;

        // Querying the table ContactsContract.Contacts to retrieve all the contacts
        Cursor contactsCursor = getActivity().getContentResolver().query(contactsUri, null, null, null,
                ContactsContract.Contacts.DISPLAY_NAME + " ASC ");

        if(contactsCursor.moveToFirst()){
            do{
                long contactId = contactsCursor.getLong(contactsCursor.getColumnIndex("_ID"));

                Uri dataUri = ContactsContract.Data.CONTENT_URI;

                // Querying the table ContactsContract.Data to retrieve individual items like
                // home phone, mobile phone, work email etc corresponding to each contact
                Cursor dataCursor = getActivity().getContentResolver().query(dataUri, null,
                                        ContactsContract.Data.CONTACT_ID + "=" + contactId,
                                        null, null);

                String displayName="";

                    do{

                            if(photoByte != null) {
                                Bitmap bitmap = BitmapFactory.decodeByteArray(photoByte, 0, photoByte.length);

                                // Getting Caching directory
                                File cacheDirectory = getActivity().getBaseContext().getCacheDir();

                                // Temporary file to store the contact image
                                File tmpFile = new File(cacheDirectory.getPath() + "/wpta_"+contactId+".png");

                                // The FileOutputStream to the temporary file
                                try {

                                    // Writing the bitmap to the temporary file as png file
                                    bitmap.compress(Bitmap.CompressFormat.PNG, 100, fOutStream);

                                    // Flush the FileOutputStream

                                    //Close the FileOutputStream

                    // Adding id, display name, path to photo and other details to cursor
                    mMatrixCursor.addRow(new Object[]{Long.toString(contactId), displayName, number, photoPath});
