Question

我正在开发短信应用程序，需要列出短信对话。尝试使用uri content://mms-sms/conversations/访问内容提供商时发现了问题。它在Android 2.3上运行良好，但在Android 4.0.3三星galaxy tab 2上运行时会返回错误：

我花了我的时间在谷歌搜索但仍然没有找到答案。知道的任何人请帮助我，我为这个恼人的问题而烦恼:(

Answer 1

可以通过此查询检索对话列表：

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

此处的关键点是URI content://mms-sms/conversations?simple=true。

看here

content：// mms-sms / conversations /在Android ICS Samsung上返回NullPointerException
