treść: // mms-sms/rozmowy/zwrot NullPointerException na Androidzie ICS Samsung

Question

Zajmuję się tworzeniem aplikacji SMS i potrzebuję wymieniać wiadomości SMS. Znalazłem problem podczas próby uzyskania dostępu do dostawcy treści przy użyciu URI content://mms-sms/conversations/. To działa dobrze na Androida 2.3, ale gdy uruchomić na Androidzie 4.0.3 Samsung Galaxy Tab 2 zwróci błąd:

ja wydano moich poszukiwań razem na google, ale nadal nie znalazłem odpowiedzi. Każdy, kto wie, proszę mi pomóc, utknąłem za ten przykry problem :(

Answer 1

Lista rozmów mogą być pobierane za pośrednictwem tego zapytania.

Uri.parse("content://mms-sms/conversations?simple=true"); 
Cursor cursor = context.getApplicationContext().getContentResolver().query(uri, null, null, null, null); 

Keypoint Oto URI content://mms-sms/conversations?simple=true
