targetActivityattribute. The target must be in the same application as the alias and it must be declared before the alias in the manifest.
The alias presents the target activity as a independent entity.
It can have its own set of intent filters, and 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 may
specify the "
" flags, causing it to be
represented in the application launcher, even though none of the
filters on the target activity itself set these flags.

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.

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 would not know its name)

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 "

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