Add this code to an onclick event:

 homeIntent.addCategory( Intent.CATEGORY_HOME );
 homeIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
 startActivity(homeIntent);

Try this on a call. I sometimes use it in onClick of a button.

<pre><code>Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
</code></pre>

It instead of closing your app , opens the dashboard so kind of looks like your app is closed.

Use this.finishAffinity(); on that button instead of finish(); 
If it does not work then you can also try by adding android:noHistory="true" in your manifest and then finish your activity by uisng finish(); or finishAffinity();

If you use both finish and exit your app will close complitely 

finish();

System.exit(0);

I am sure this question has been asked number of times because I read a few. My client wants me to put a button into his app where users can click and exit. I have read <a href="https://stackoverflow.com/questions/2033914/quitting-an-application-is-that-frowned-upon/2034238">this</a> and found calling <code>finish()</code> will do it. But, finish is only closing the current running activity right? I have lot of activities so in this case I have to pass each and every activity's instance and finish them or make every activity into Singleton pattern. 

I also got to know <code>Activity.moveTaskToBack(true)</code> can get you into the home screen. OK, this is not closing but backgrounding the process. So is this is effective?

Which method should I use to close the app completely? Any of above described or any other method/other usage of above methods?

How to exit an Android app programmatically?

Android

Xamarin

我相信这个问题已经被问了很多次了，因为我读过一些。我的客户希望我在他的应用程序中添加一个按钮，用户可以点击并退出。我已经阅读了，并发现调用finish()可以做到这一点。但是，finish只是关闭当前正在运行的活动，对吗？我有很多活动，所以在这种情况下，我必须传递每个活动的实例并完成它们，或者将每个活动转换为Singleton模式。我还知道Activity.moveTaskToBack(true)
