Extra info for Application Security for the Android Platform: Processes, Permissions, and Other Safeguards
Unfortunately, this is not always a straightforward task. The Android APIs, and other interaction mechanisms, are documented online, and many of the methods that require a permission to successfully execute document that fact. However, not all do. Indeed, as each API is responsible for making its own permission checks, and each API developer is responsible for his own documentation, the API documentation is not 100% complete with regard to permissions required. Indeed, Internet message boards and other methods of developer communications are often filled with questions as to which permissions certain APIs require and so on.
The permissions system is a powerful construct that is meant to be used and extended by app developers outside the core Android developers. We have seen that an app needs to specify which permissions it requires in its manifest. The question then remains: how are these permissions granted? This is all handled when the app is installed. xml file is read and the list of all permissions it needs to run is parsed. The installer then generates a list of these permissions (not all of them, as we will see in a bit) and prompts the user to review and approve them.
As Content Providers are typically used to share data across apps, properly securing them so that appropriate apps can access specific data is critical; we will soon see how to accomplish this. xml, and points to the Content Provider itself that will handle the reference (this is usually the full, all lowercase name of the implementing class). The path can be any number of segments, from zero on up, and is used by the Content Provider to find the data in question. In a basic implementation, the path would simply be the name of the table that the data is in.
