什么是Android邮件内容URI。 形成电子邮件客户端源$ C ​​$ CI得到以下URI

 内容：//com.android.email.provider/body
内容：//com.android.email.provider/message
内容：//com.android.email.provider/syncedMessage
内容：//com.android.email.provider/deletedMessage
内容：//com.android.email.provider/updatedMessage
内容：//com.android.email.provider/account
内容：//com.android.email.provider/accountIdAddToField
内容：//com.android.email.provider/attachment
内容：//com.android.email.provider/attachment/message
内容：//com.android.email.provider/mailbox
内容：//com.android.email.provider/mailboxIdAddToField
内容：//com.android.email.provider/hostauth
 

但没有返回游标当我运行下面的code。

 开放的URI = Uri.parse（内容：//com.android.email.provider/account）;
光标光标= mContext.getContentResolver（）查询（URI，NULL，NULL，NULL，NULL）;
 

任何人都没有我怎么可以访问电子邮件的内容？

感谢。

有谁知道我可以访问电子邮件   内容是什么？

电子邮件程序不是SDK的一部分。它可以取代在Android设备上。内容提供者可以在安卓的未来版本中改变。用户可能无法使用摆在首位的电子邮件程序，使用Gmail，K-9或其他第三方应用程序。

目前所有的原因preventing电子邮件经由操作系统被访问了有益的探讨：的 http://comments.gmane.org/gmane.comp.handhelds.android.devel/137111

The Email program is not part of the SDK. It can be replaced on Android devices. The content providers can change in future versions of Android. The user might not be using that email program in the first place, using Gmail, K-9, or another third party application.

There is a useful discussion of all the reasons preventing email from being accessed via the OS: http://comments.gmane.org/gmane.comp.handhelds.android.devel/137111
