Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

和使用这种方法

moveTaskToBack(true);

我开发一个应用程序，并在我需要退出它的最后一项活动，我已经使用了退出应用程序的问题是，它存在的唯一的活动和应用程序在后台运行上面的方法（见于任务经理）。每当我重新加载应用程序就开始在我离开它（最后一项活动）。

I'm developing an application and at the last activity I need to exit it, I have used the above methods which exits the application the problem is it exists the ONLY the activity and the application runs in background (seen in the task manager). Whenever I load the application again it starts with where I exit it (the last activity).

有没有code彻底退出，并同时删除表格的背景（任务管理器）。

is there any code to exit it completely and also remove form background(task manager).

在此先感谢。

推荐答案

要退出应用程序，返回到您的根系活力这种方式（即第一个启动器启动活动）：

To exit your application, return to your root activity (the activity that is the first one the launcher starts) this way:

Intent intent = new Intent(this, MyRootActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addExtra("exit", "true");
startActivity(intent);

这将清除任务堆栈下到根系活力，然后用这个意图再次启动根系活力。

This will clear the task stack down to the root activity and then start the root activity again with this intent.

在您的根系活力，在的onCreate（）您需要确定阉基础上的意图演员退出，像这样的：

In your root activity, in onCreate() you need to determine wether to exit based on the extras in the intent, like this:

Intent intent = getIntent();
if (intent.hasExtra("exit")) {
    // User wants to exit
    finish();
}

您也谈一下从任务管理器中删除您的应用程序。如果指的是最近的应用程序的列表这不是​​运行的应用程序的列表，它是用户最近使用的应用程序的列表。仅仅因为你的应用程序显示在那里并不意味着它正在运行。

You also say something about removing your app from the task manager. If you are referring to the "list of recent apps" this isn't a list of the "running applications", it is a list of the applications that the user recently used. Just because your app shows up there does not mean that it is running.

如果你真的想你的应用程序不会显示在最近的应用程序列表，只是将它添加到您的根系活力清单条目：

If you really want your app not to show up in the "list of recent apps", just add this to the manifest entry for your root activity:

android:excludeFromRecents="true"
