推荐答案

"singleTask"和"singleInstance"模式也各不相同 其他仅在一个方面:"singleTask"活动允许其他 活动是其任务的一部分.它始终是其根源 任务，但其他活动(必要时是标准"和单顶" 活动)可以启动到该任务中.一个"singleInstance" 另一方面，活动不允许其他活动成为其中的一部分 它的任务.这是任务中唯一的活动.如果它开始另一个 活动，则该活动被分配给其他任务-好像 有意参加FLAG_ACTIVITY_NEW_TASK.

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.
