Dastur natijasi


Constant o‘zgaruvchilarga misollar:
▶ Browser.BOOKMARKS_URI
▶ Browser.SEARCHES_URI
▶ CallLog.CONTENT_URI
▶ MediaStore.Images.Media.INTERNAL_CONTENT_URI
▶ MediaStore.Images.Media.EXTERNAL_CONTENT_URI
▶ Settings.CONTENT_URI
▶ Contact ma’lumotlaridan birinchisini (ID=1) o‘qish uchun quyidagi so‘rovni yazamiz:

▶ Uri allContacts = Uri.parse(“content://contacts/people/1”);

▶ Constant o‘zgaruvchilar orqali murojaat qilishimizda esa maxsus ContentUris sinfining withAppendedId() metodidan foydalaniladi:

▶ Uri allContacts =

ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, 1);
