Similarly, if a license name has a spelling error, the installation may fail because the domain does not have a permission for spelling errors. The MIDP 2.0 defines four protection domains for GS

In the security model of the Android system, the application is not allowed to perform any actions that adversely affect other applications, systems or users by default. If your app needs to do something, you need to declare the permissions that are used for that operation.

Of course, more function groups may be added in the future. Function groups also define different interaction methods for different domains. For example, in untrusted domains, "net access" (Network Access) is set to session (for short term) or denied, and can be set to oneshot, blanket, or denied in a trusted domain. 3.
