problems with implicit intents
<p>now i am learning intent filters..I got some some example like view contacts,make call.But all in those examples they used default  in android.manifestfile..</p>

<pre><code>&lt; intent-filter &gt;
     &lt;action android:name="android.intent.action.MAIN" &gt;
     &lt;category android:name="android.intent.category.LAUNCHER" &gt;
&lt; /intent-filter&gt;
</code></pre>

<p>this is ok for single .java file application.If i am using  implicit intent in my second activity, then how will be the  of my second activity manifest file?..just take the examplw of view contact....
Intent contact=new Intent(Intent.ACTION_VIEW,ContactsContract.Contacts.CONTENT_URI);
my class name is ViewContacts.java and package name is com.phone.contact...</p>
