* This class gives information about, and interacts * with, activities, services, and the containing * process. *
* ** A number of the methods in this class are for * debugging or informational purposes and they should * not be used to affect any runtime behavior of * your app. These methods are called out as such in * the method level documentation. *
* ** Most application developers should not have the need to * use this class, most of whose methods are for specialized * use cases. However, a few methods are more broadly applicable. * For instance, {@link android.app.ActivityManager#isLowRamDevice() isLowRamDevice()} * enables your app to detect whether it is running on a low-memory device, * and behave accordingly. * {@link android.app.ActivityManager#clearApplicationUserData() clearApplicationUserData()} * is for apps with reset-data functionality. *
* ** In some special use cases, where an app interacts with * its Task stack, the app may use the * {@link android.app.ActivityManager.AppTask} and * {@link android.app.ActivityManager.RecentTaskInfo} inner * classes. However, in general, the methods in this class should * be used for testing and debugging purposes only. *
