Package naming uniqueness for applications?
<p>When creating an android app, we need to supply a package name in the manifest.</p>

<pre><code>&lt;manifest
  xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.me.foo"&gt;
</code></pre>

<p>I believe this uniquely identifies an application, such that we can't upload an app to marketplace if another app already exists with the same package name.</p>

<p>Is it possible to extend a package name though without collision? For example:</p>

<pre><code>package="com.me.foo"
package="com.me.foo.grok"
</code></pre>

<p>Will the second application be accepted by the marketplace, even though it's a substring of the first package name? </p>

<p>Thanks</p>
