<dt>description:</dt>
<dd>The root element of the AndroidManifest.xml file.  It must 
contain an <code><a href="{@docRoot}guide/topics/manifest/application-element.html">&lt;application&gt;</a></code> element 
and specify {@code xlmns:android} and {@code package} attributes.</dd>

<dt>attributes:</dt>
<dd><dl class="attr">
<dt><a name="nspace"></a>{@code xmlns:android}</dt>
<dd>Defines the Android namespace.  This attribute should always be set 
to "{@code http://schemas.android.com/apk/res/android}".</dd>

<dt><a name="package"></a>{@code package}</dt>
<dd>A full Java package name for the application.  The name should 
be unique.  For example, applications published by Google could have 
names in the form <code>com.google.app.<i>application_name</i></code>.

<p>
The package name serves as a unique identifier for the application.  
It's also the default name for the application process (see the 
<code><a href="{@docRoot}guide/topics/manifest/application-element.html">&lt;application&gt;</a></code>
element's
<code><a href="{@docRoot}guide/topics/manifest/application-element.html#aff">process</a></code>
process</a></code> attribute) and the default task affinity of an activity
(see the 
<code><a href="{@docRoot}guide/topics/manifest/activity-element.html">&lt;activity&gt;</a></code> 
element's
<code><a href="{@docRoot}guide/topics/manifest/activity-element.html#aff">taskAffinity</a></code> attribute).
</p></dd>

<dt><a name="uid"></a>{@code android:sharedUserId}</dt>
<dd>The name of a Linux user ID that will be shared with other applications.  
By default, Android assigns each application its own unique user ID.  
However, if this attribute is set to the same value for two or more applications, 
they will all share the same ID &mdash; provided that they are also signed 
by the same certificate.  Application with the same user ID can access each 
other's data and, if desired, run in the same  process.</dd>  

<dt><a name="vcode"></a>{@code android:versionCode}</dt>
<dd>An internal version number.  This number is used only to determine whether 
one version is more recent than another, with higher numbers indicating more 
recent versions.  This is not the version number shown to users; that number 
is set by the {@code versionName} attribute.

<p>
The value must be set as an integer, such as "100".  You can define it however
you want, as long as each successive version has a higher number.  For example, 
it could be a build number.  Or you could translate a version number in "x.y" 
format to an integer by encoding the "x" and "y" separately in the lower and 
upper 16 bits.  Or you could simply increase the number by one each time a new 
version is released.
</p></dd>

<dt><a name="vname"></a>{@code android:versionName}</dt>
<dd>The version number shown to users.  This attribute can be set as a raw 
string or as a reference to a string resource.  The string has no other purpose 
than to be displayed to users.  The {@code versionCode} attribute holds 
the significant version number used internally.
