description:
The declaration of the application. This element contains subelements that declare each of the application's components and has attributes that can affect all the components. Many of these attributes (such as icon, label, permission, process, taskAffinity, and allowTaskReparenting) set default values for corresponding attributes of the component elements. Others (such as debuggable, enabled, description, and allowClearUserData) set values for the application as a whole and cannot be overridden by the components.
attributes
android:allowClearUserData
Whether or not users are given the option to remove user data — "true" if they are, and "false" if not. If the value is "true", as it is by default, the application manager includes an option that allows users to clear the data.
android:allowTaskReparenting
Whether or not activities that the application defines can move from the task that started them to the task they have an affinity for when that task is next brought to the front — "true" if they can move, and "false" if they must remain with the task where they started. The default value is "false".

The <activity> element has its own allowTaskReparenting attribute that can override the value set here. See that attribute for more information.

android:debuggable
Whether or not the application can be debugged, even when running on a device in user mode — "true" if it can be, and "false" if not. The default value is "false".
android:description
User-readable text about the application, longer and more descriptive than the application label. The value must be set as a reference to a string resource. Unlike the label, it cannot be a raw string. There is no default value.
android:enabled
Whether or not the Android system can instantiate components of the application — "true" if it can, and "false" if not. If the value is "true", each component's enabled attribute determines whether that component is enabled or not. If the value is "false", it overrides the component-specific values; all components are disabled.

The default value is "true".

android:hasCode
Whether or not the application contains any code — "true" if it does, and "false" if not. When the value is "false", the system does not try to load any application code when launching components. The default value is "true".

An application would not have any code of its own only if it's using nothing but built-in component classes, such as an activity that uses the AliasActivity class, a rare occurrence.

android:icon
An icon for the application as whole, and the default icon for each of the application's components. See the individual icon attributes for <activity>, <activity-alias>, <service>, <receiver>, and <provider> elements.

This attribute must be set as a reference to a drawable resource containing the image definition. There is no default icon.

android:label
A user-readable label for the application as a whole, and a default label for each of the application's components. See the individual label attributes for <activity>, <activity-alias>, <service>, <receiver>, and <provider> elements.

The label should be set as a reference to a string resource, so that it can be localized like other strings in the user interface. However, as a convenience while you're developing the application, it can also be set as a raw string.

android:manageSpaceActivity
The fully qualified name of an Activity subclass that the system can launch to let users manage the memory occupied by the application on the device. The activity should also be declared with an <activity> element.
android:name
The fully qualified name of an Application subclass implemented for the application. When the application process is started, this class is instantiated before any of the application's components.

The subclass is optional; most applications won't need one. In the absence of a subclass, Android uses an instance of the base Application class.

android:permission
The name of a permission that clients must have in order to interact with the application. This attribute is a convenient way to set a permission that applies to all of the application's components. It can be overwritten by setting the permission attributes of individual components.

For more information on permissions, see the Permissions section in the introduction and another document, Security and Permissions.

android:persistent
Whether or not the application should remain running at all times — "true" if it should, and "false" if not. The default value is "false". Applications should not normally set this flag; persistence mode is intended only for certain system applications.
android:process
The name of a process where all components of the application should run. Each component can override this default by setting its own process attribute.

By default, Android creates a process for an application when the first of its components needs to run. All components then run in that process. The name of the default process matches the package name set by the <manifest> element.

By setting this attribute to a process name that's shared with another application, you can arrange for components of both applications to run in the same process — but only if the two applications also share a user ID and be signed with the same certificate.

If the name assigned to this attribute begins with a colon (':'), a new process, private to the application, is created when it's needed. If the process name begins with a lowercase character, a global process of that name is created. A global process can be shared with other applications, reducing resource usage.

android:taskAffinity
An affinity name that applies to all activities within the application, except for those that set a different affinity with their own taskAffinity attributes. See that attribute for more information.

By default, all activities within an application share the same affinity. The name of that affinity is the same as the package name set by the <manifest> element.

android:theme
A reference to a style resource defining a default theme for all activities in the application. Individual activities can override the default by setting their own theme attributes; see that attribute for more information.
