Question

我有一个Android应用程序。如果我通过活动（例如MainTabActivity-＆gt; SearchMapActivity-＆gt; ListBranchesActivity）然后隐藏（不关闭）我的应用程序，android将在重新打开后运行main（MainTabActivity）活动。如果我按＆＃34;返回＆＃34;按钮，android会显示最后一个活动（ListBranchesActivity）。如何让我的应用程序在恢复后显示最后一个活动？我真的不知道如何实现这一目标。有人说要向清单添加singleTask语句。我的清单：

            </intent-filter>
        </activity>
    </application>

此外，事情并非每次都发生。有时它显示最后的活动，有时 - 主要活动。

如果需要内存，有时android会关闭你的应用程序。所以，即使你hide(not close) ...[the] application,它可能已被关闭

恢复后如何运行上次查看的活动？
