Creating android content provider by "extending" / "not extending" ContentProvider class
<p>Q-1 - To create my own Content Provider class, when I should extend ContentProvider class and when I should not extend ContentProvider class ?</p>

<p>Q-2 - If I create Content Provider without CONTENT_URI(like many other built-in content providers in android.provider.*, how will I use managedQuery(...) or query(....).</p>

<p>I have seen response to similar question in <a href="http://stackoverflow.com/questions/2358459/content-provider-in-android-basic-questions">this question on content provider</a> but I am not sure they answer it completly.</p>
