nội dung: // mms-sms/conversation/return NullPointerException tại Android ICS Samsung

Question

Tôi đang phát triển ứng dụng SMS và cần liệt kê cuộc trò chuyện SMS. Tôi đã gặp sự cố khi cố gắng truy cập vào nhà cung cấp nội dung bằng cách sử dụng uri content://mms-sms/conversations/. Đó là chạy tốt trên Android 2.3 nhưng khi chạy ở Android 4.0.3 Samsung galaxy tab 2 nó trả về lỗi:

Tôi đã dành thời gian tìm kiếm của tôi nó trên google nhưng vẫn không tìm thấy câu trả lời. Bất cứ ai biết xin hãy giúp tôi, tôi bị mắc kẹt cho vấn đề này gây phiền nhiễu :(

Answer 1

Danh sách các cuộc hội thoại có thể được lấy thông qua truy vấn này:.

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

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