解决方案

好纳雷什你可以做这样的事情
首先完成从中正在关闭应用程序this.finish活动（）;其次，最impotantly总是设置一个标志i.addFlags（Intent.FLAG_ACTIVITY_CLEAR_TOP）;
当你从一个活动切换到另一个活动的这个明确的顶部和你知道每一项活动是保存在栈因此该标志由上删除旧的活动等等在你的整个应用程序只有一个活动被保存在栈<在顶推新活动/ p>

如果这不起作用把整个应用程序在后台由avtivityname.moveTaskToBack（）;这将移动您的整个应用程序在回地面，但只有一个，当你开始你的活动缺点，它会显示你从你已经搬回了活动

My Application have 20 activities.

Well naresh you can do something like that first finish the activity from which you are closing application this.finish(); secondly and most impotantly always set a flag i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); this clear top when you switch from one activity to another activity and as you know every activity is kept in stack to so this flag remove old activity from top and push new activity in top so around your whole application only one activity is kept in stack

and if this does not work put the whole application in background by avtivityname.moveTaskToBack(); this will move your whole app in back ground but only one drawback when you start your activity it will show your that activity from which you have moved back
