description:
:   An alias for an activity, named by the `targetActivity`
    attribute. The target must be in the same application as the
    alias and declared before the alias in the manifest.


    The alias presents the target activity as an independent entity, and can have its own set of intent
    filters. They, rather than the
    intent filters on the target activity itself, determine which intents
    can activate the target through the alias and how the system
    treats the alias.

    For example, the intent filters on the alias might
    specify the ["android.intent.action.MAIN"](https://developer.android.com/reference/android/content/Intent#ACTION_MAIN)
    and ["android.intent.category.LAUNCHER"](https://developer.android.com/reference/android/content/Intent#CATEGORY_LAUNCHER)" flags, causing it to
    be represented in the application launcher, even though none of the
    filters on the target activity itself set these flags.


    With the exception of `targetActivity`, `<activity-alias>`
    attributes are a subset of [<activity>](https://developer.android.com/guide/topics/manifest/activity-element) attributes.
    For attributes in the subset, none of the values set for the target carry over
    to the alias. However, for attributes not in the subset, the values set for
    the target activity also apply to the alias.

attributes:
:

    `android:enabled`
    :   Whether the target activity can be instantiated by the system through
        this alias. `"true"` if it can be, and `"false"` if not.
        The default value is `"true"`.


        The [<application>](https://developer.android.com/guide/topics/manifest/application-element) element has its own
        [enabled](https://developer.android.com/guide/topics/manifest/application-element#enabled) attribute that applies to all
        application components, including activity aliases. The
        `<application>` and `<activity-alias>`
        attributes must both be `"true"` for the system to be able to instantiate
        the target activity through the alias. If either is `"false"`, the alias
        doesn't work.

    `android:exported`
    :   Whether the components of other applications can launch the target activity
        through this alias. `"true"` if they can, and `"false"` if not.
        If `"false"`, the target activity can be launched through the alias only by
        components of the same application as the alias or applications with the same user ID.


        The default value depends on whether the alias contains intent filters. The
        absence of any filters means that the activity can be invoked through the alias
        only by specifying the exact name of the alias. This implies that the alias
        is intended only for application-internal use, since others don't know its name.
        So, the default value is `"false"`.
        On the other hand, the presence of at least one filter implies that the alias
        is intended for external use, so the default value is `"true"`.

    `android:icon`
    :   An icon for the target activity when presented to users through the alias.
        For more information, see the [<activity>](https://developer.android.com/guide/topics/manifest/activity-element) element's
        [icon](https://developer.android.com/guide/topics/manifest/activity-element#icon) attribute.

    `android:label`
    :   A user-readable label for the alias when presented to users through the alias.
        For more information, see the [<activity>](https://developer.android.com/guide/topics/manifest/activity-element) element's
        [label](https://developer.android.com/guide/topics/manifest/activity-element#label) attribute.

        <br />

    `android:name`

    :   A unique name for the alias. The name resembles a fully qualified class name. But, unlike the name of the target activity, the alias name is arbitrary. It doesn't refer to an actual class. <br />

    `android:permission`
    :   The name of a permission that clients must have to launch the target activity
        or get it to do something using the alias. If a caller of
        [startActivity()](https://developer.android.com/reference/android/content/Context#startActivity(android.content.Intent)) or
        [startActivityForResult()](https://developer.android.com/reference/android/app/Activity#startActivityForResult(android.content.Intent, int))
        isn't granted the specified permission, the target activity isn't activated.

        This attribute supplants any permission set for the target activity itself. If
        it isn't set, a permission isn't needed to activate the target through the alias.


        For more information about permissions, see the
        [Permissions](https://developer.android.com/guide/topics/manifest/manifest-intro#perms)
        section in the app manifest overview.

    `android:targetActivity`
    :   The name of the activity that can be activated through the alias.
        This name must match the `name` attribute of an
        [<activity>](https://developer.android.com/guide/topics/manifest/activity-element) element that precedes
        the alias in the manifest.
