/// anywhere in the activity stack. Typically, they're launched into the
/// task that called [`startActivity()`] (unless the Intent object contains a
/// [`FLAG_ACTIVITY_NEW_TASK`] instruction, in which case a different task is
/// chosen — see the [`taskAffinity`] attribute).
///
/// In contrast, `"singleTask"` and `"singleInstance"` activities can only begin a
/// task. They are always at the root of the activity stack. Moreover, the
/// device can hold only one instance of the activity at a time — only one
/// such task.
///
/// The `"standard"` and `"singleTop"` modes differ from each other in just one
/// respect: Every time there's a new intent for a `"standard"` activity, a new
/// instance of the class is created to respond to that intent. Each instance
/// handles a single intent. Similarly, a new instance of a `"singleTop"` activity
/// may also be created to handle a new intent. However, if the target task
/// already has an existing instance of the activity at the top of its stack, that
/// instance will receive the new intent (in an [`onNewIntent()`] call); a new
/// instance is not created. In other circumstances — for example, if an existing
/// instance of the `"singleTop"` activity is in the target task, but not at
/// the top of the stack, or if it's at the top of a stack, but not in
/// the target task — a new instance would be created and pushed on the
/// stack.
///
/// Similarly, if you [`navigate up`] to an activity on the current stack, the behavior is
/// determined by the parent activity's launch mode. If the parent activity has
/// launch mode `singleTop` (or the `up` intent contains [`FLAG_ACTIVITY_CLEAR_TOP`]),
/// the parent is brought to the top of the stack, and its state is preserved. The
/// navigation intent is received by the parent activity's [`onNewIntent()`] method.
/// If the parent activity has launch mode standard (and the up intent does not
/// contain [`FLAG_ACTIVITY_CLEAR_TOP`]), the current activity and its parent
/// are both popped off the stack, and a new instance of the parent activity
/// is created to receive the navigation intent.
///
/// The "singleTask" and "singleInstance" modes also differ from each other in only
/// one respect: A "singleTask" activity allows other activities to be part of its
/// task. It's always at the root of its task, but other activities (necessarily
/// "standard" and "singleTop" activities) can be launched into that task. A
/// "singleInstance" activity, on the other hand, permits no other activities to be
/// part of its task. It's the only activity in the task. If it starts another
/// activity, that activity is assigned to a different task — as if
/// FLAG_ACTIVITY_NEW_TASK was in the intent.
///
/// As shown in the enum variant description, `standard` is the default mode and is
/// appropriate for most types of activities. `SingleTop` is also a common and useful
/// launch mode for many types of activities. The other modes — `singleTask` and
/// `singleInstance` — are `not appropriate for most applications`, since they result in
