mediastore - Android deleting the micro_kind thumbnails after image file deletion -


i populating gridview micro_kind thumbnails using following:

  /* find images of interest   */      imagecursor =    getactivity().getcontentresolver().query(mediastore.images.media.external_con  tent_uri,                 columns,                 mediastore.images.media.data + " ? ",                 new string[]{"%/housetab" + currenthousenumber + "/%"},                 null);  /* retrieve micro_kind thumbnails   */ int id = imagecursor.getint(image_column_index); thumbnails[i] = mediastore.images.thumbnails.getthumbnail(                     getactivity().getapplicationcontext().getcontentresolver(), id,                     mediastore.images.thumbnails.micro_kind, null);

the retrieve process works perfectly; issue happen when delete actual image files can not delete micro_kind thumbnails. using right , files images gets deleted micro_kind not deleted , still visible in gridview after refresh. rid of thumbnail have turn off device or unmount/mount of sdcard.

  int count = imagecursor.getcount();     int image_column_index = imagecursor.getcolumnindex(mediastore.images.media._id);     contentresolver cr = getactivity().getapplicationcontext().getcontentresolver();      (int = 0; < count; i++) {         new file(arrpath[i]).delete(); // delete actual image file         imagecursor.movetoposition(i);          long id = imagecursor.getint(image_column_index);          /* delete thumbnails ???? not working    */         cr.delete(mediastore.images.thumbnails.external_content_uri, mediastore.images.thumbnails.image_id +                 "= ?",new string[]{"" + id});

by way arrpath retrieve mediastore using following:

int datacolumnindex = imagecursor.getcolumnindex(mediastore.images.media.data); arrpath[i] = imagecursor.getstring(datacolumnindex);

i try following delete thumbnails without success.

 mediascannerconnection.scanfile(             getactivity().getapplicationcontext(),             new string[]{arrpath[i]},             null,             new mediascannerconnection.onscancompletedlistener() {                 @override                 public void onscancompleted(string path, uri uri) {                     refreshimages();                 }             });

so how remove entry database when imagecursor refreshed after file deletion imagecursor empty , no micro_kind or data matter returned???

any appreciated.

hopefully others. manage delete entry mediastore hence micro_kind thumbnails using following:

 uri uri = contenturis.withappendedid(mediastore.images.media.external_content_uri,             id);     cr.delete(uri,null,null);

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
