Struct android_manifest::Permission [−][src]
pub struct Permission { pub description: Option<Resource<StringResource>>, pub icon: Option<Resource<DrawableResource>>, pub label: Option<StringResourceOrString>, pub name: Option<String>, pub permission_group: Option<String>, pub protection_level: Option<ProtectionLevel>, }
Expand description
Declares a security permission.
That can be used to limit access to specific components or features of this
or other applications. See the Permissions
section in the introduction, and the
Security and Permissions
document for more information on how permissions work.

Fields
description: Option<Resource<StringResource>>
A user-readable description of the permission, longer and more informative than the label. It may be displayed to explain the permission to the user — for example, when the user is asked whether to grant the permission to another application.
This attribute must be set as a reference to a string resource; unlike the label
unlike the label
attribute, it cannot be a raw string.
icon: Option<Resource<DrawableResource>>
A reference to a drawable resource for an icon that represents the permission.
label: Option<StringResourceOrString>
A name for the permission, one that can be displayed to users. As a convenience, the label can be directly set as a raw string while you’re developing the application. However, when the application is ready to be published, it should be set as a reference to a string resource, so that it can be localized like other strings in the user interface.
name: Option<String>
The name of the permission. This is the name that will be used in code to refer to
the permission — for example, in a <uses-permission>
element and the
permission attributes of application components.
Note
The system does not allow multiple packages to declare a permission with
the same name, unless all the packages are signed with the same
certificate. If a package declares a permission, the system does not
permit the user to install other packages with the same permission
name, unless those packages are signed with the same certificate as
the first package. To avoid naming collisions, we recommend using
reverse-domain-style naming for custom permissions, for example
com.example.myapp.ENGAGE_HYPERSPACE
.
permission_group: Option<String>
Assigns this permission to a group. The value of this attribute is the name of the
group, which must be declared with the <permission-group>
element in this
or another application. If this attribute is not set, the permission does not
belong to a group.
protection_level: Option<ProtectionLevel>
Characterizes the potential risk implied in the permission and indicates the procedure the system should follow when determining whether or not to grant the permission to an application requesting it.
Each protection level consists of a base permission type and zero or more flags.
For example, the "dangerous"
protection level has no flags. In contrast,
the protection level "signature|privileged"
is a combination of the
"signature"
base permission type and the "privileged"
flag.
