內容：// mms-sms /對話/返回NullPointerException在Android ICS三星

我正在開發短信應用程序，並需要列出短信對話。嘗試使用uri content://mms-sms/conversations/訪問內容提供商時發現問題。它運行良好，在Android 2.3，但是當在Android上運行4.0.3三星Galaxy Tab 2也返回錯誤：內容：// mms-sms /對話/返回NullPointerException在Android ICS三星

看起來'Samsung galaxy tab 2'改變了URI路徑，我的代碼在運行4.1.2的NexusS上運行良好，因爲直接訪問消息傳遞提供程序不是公共sdk，所以你必須忍受它，根或試圖找到真正的路徑'msssms.db' –

只是一個說明：你不應該*依賴*內容：//短信或任何類似的行爲沒有記錄，因此可能會改變或刪除設備或版本之間。 – Eric

感謝Eric，但它是現在訪問SMS數據庫的唯一方式，對嗎？當我添加threadID如：content：// mms-sms/conversations/xxx'時，uri路徑工作正常，但當沒有提到threadID時，它會變成空指針 – Jevrier

會話列表可以通過這個查詢檢索：

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

關鍵點這裏的URI content://mms-sms/conversations?simple=true

當我在4.0操作系統版本上運行這個查詢時，它只返回11列[_id，date，message_count，readcount，recipient_ids，snippet，snippet_cs，read，type，error，has_attachment，status]我需要thread_id，運行內容：// mms-sms /對話/ 2.3.6操作系統版本上的這個查詢，你能告訴我需要做什麼才能得到高於4.0的完整列謝謝你的關注.. –

@kamal_tech_view'_id' is 'thread_id' :) – barmaley

謝謝我解決了我的問題... –
