Application Manager

---

The Application Manager API provides functions to get information about installed or running applications and manage the applications.

Required Header

#include <app_manager.h>

Overview

The Application Manager API provides information about applications. There are several different sorts of queries. Two iterator functions step through a list of applications. One is used in running applications(app_manager_foreach_app_context()), and the other is used in available ("installed") but not necessarily running applications(app_manager_foreach_app_info()). Each will call a callback function, passing the package name of each application found. A query function will respond whether the application represented by a particular package name is running. Other query functions return static information about an application, such as a name, a type, an icon path, or a version. The API provides functions to manage applications also. By using them, it is possible to resume(app_manager_resume_app) applications.
