The package name serves as a unique identifier for the application.
It's also the default name for the application process (see the
process attribute) and the default task affinity of an activity
- 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 — 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.
- A user-readable label for the shared user ID. The label must be set as
a reference to a string resource; it cannot be a raw string.
This attribute was introduced in API Level 3. It is meaningful only if the
sharedUserId attribute is also set.
- 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
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.
- 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
versionCode attribute holds
the significant version number used internally.
