Application policy use cases
This section discusses how to define the application policies using the manifest file. I have used use cases and we will discuss how to implement these use cases in the policy file.
Declaring application permissions
An application on the Android platform has to declare what resources it intends to use for proper functioning of the application. These are the permissions that are displayed to the user when they download the application. As discussed in Chapter 3, Permissions, an application can define custom permissions as well. Application permissions should be descriptive so that users can understand them. Also, as is the general rule with security, it is important to request the minimum permissions required.
Application permissions are declared in the manifest file by using the tag <uses-permission>. An example of a location-based manifest file that uses the GPS for retrieving location is shown in the following code snippet:
<uses-permissionandroid:name...
