content provider public fields access
<p>A content provider is expected, according to various documentation like <a href="http://developer.android.com/guide/topics/providers/content-providers.html" rel="nofollow">http://developer.android.com/guide/topics/providers/content-providers.html</a>,
to define final Strings for the URI name and the column names, so that client can access them.
This suggests that clients have direct access to the class public fields.
But a class can not directly access classes in other apks.
How can I write a custom content provider accessible from classes in other apks and how can the clients get the URI and column names ?</p>
