Why android Messaging app is launched when I start an ACTION_SEND intent with */* mimeType type
<p>I look at the android Messaging App source code, the manifest file said:</p>

<pre><code>  &lt;intent-filter&gt;
       &lt;action android:name="android.intent.action.SEND" /&gt;
       &lt;category android:name="android.intent.category.DEFAULT" /&gt;
       &lt;data android:mimeType="image/*" /&gt;
   &lt;/intent-filter&gt;
   &lt;intent-filter&gt;
       &lt;action android:name="android.intent.action.SEND" /&gt;
       &lt;category android:name="android.intent.category.DEFAULT" /&gt;
       &lt;data android:mimeType="video/*" /&gt;
   &lt;/intent-filter&gt;
   &lt;intent-filter&gt;
       &lt;action android:name="android.intent.action.SEND" /&gt;
       &lt;category android:name="android.intent.category.DEFAULT" /&gt;
       &lt;data android:mimeType="text/plain" /&gt;
   &lt;/intent-filter&gt;
</code></pre>

<p>But why in my code, I start an Intent like this:</p>

<pre><code>Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("*/*");
</code></pre>

<p>I see the Messaging app in the pop up dialog?</p>
