android - 了解 Android list 中的提供程序属性 "android:multiprocess"

Question

在为 Android 创建移动应用程序时，我正在处理需要 ContentProvider 的 SQLite 数据库。 ContentProvider 用于从数据库中添加、更新、读取或删除数据。

我读了http://developer.android.com/guide/topics/manifest/provider-element.html但我没有找到任何进一步的信息，尤其是对于使用数据库而言。

我见过一些定义了以下提供者的 list :

<provider
    android:name="main.ContentProvider"
    android:authorities="main.ContentProvider"
    android:multiprocess="true">
</provider>

将多进程设置为 true 是什么意思？这是否意味着许多数据库查询将同时处理？如果我将它设置为 false，会发生什么？

谢谢。

一位Android框架工程师说“不要使用这个属性”

Don't use this, it is some old cruft from pre-1.0 design that doesn't work and should be ignored these days. Just pretend like the attribute doesn't exist. :}
