Whenever you wish to exit all open activities, you should press a button which loads the first Activity that runs when your application starts then clear all the other activities, then have the last remaining activity finish. to do so apply the following code in ur project

The above code finishes all the activities except for FirstActivity. Then we need to finish the FirstActivity’s Enter the below code in Firstactivity’s oncreate

and you are done.

when you want to close your application, you can call

or if you want close it in background also you should write,

This is the cleanest way I have come across:

To finish an activity or exit the app, try this..

& use this if for whatever you select to exit the app.

Exit/Finish an app/activity — android

I’ve got 4 activities say Act1 , Act2 , Act3 and Act4 . A button in Act1 opens Act2, a button in Act2 opens Act3, a button in Act3 opens Act4.

I want two things to be done:

I’ve a button in Act4 which directs the user to Act1, the prob is when the user clicks back in Act1, i want to close the app instead of opening the Act4..

I’ve option in menu ‘exit’ in all activities when the user choose it, i want to close the app instead of going back to previous activity.

Tried using finish(); but it didn’t meet my requirements.

Use below code in your Act4 ‘th Menu.xml ‘s exit button —

And, in your first activity’s onCreate() method just put the below code —

This will exit your app.

in all activities to close the app.

Clear the flag before you switch back to previous activity. It might help you.

finish previous activity when you are go to the next activity means write finish(); after startactivity(intent); and write below code for start first activity from fourth activity’s button click event.

And Write Below Code on Your Exit Button’s Click event in all activities.

Place this code in your app:

Use android:noHistory = «true» in your AndroidManifest.xml file

If you have another activity behind ( in the application activity stack), you could use finish() to exit the current activity.

However, the back function too suppose to remove the current activity from your application activity stack.

In my experience, it is very unreliable to rely on the activities in the back stack ( in the application activity stack). Because of that I used to exit each activity when I go deeper.

The above method will exit all the activities.

However, if you want to run some code in the background, it is better to rely on a «Service» rather than an «Activity». You can let the «Service» exit after doing its assigned work.

The approach I use is to start all child activities with startActivityForResult . Then I can putExtra(«STATE», some_value) on exiting any child and use the state value to determine what to do up through the parents.

If I want to exit the app from a deep child, «STATE» would be «exit» and each child in the hierarchy would simply get the StringExtra for «exit», do a putExtra(«STATE», «exit») and call finish() and then the app would call finish() in the end. You can use this to achieve any desired state.

Using startActivityForResult to pass messages this way avoids having to pass awkward references down into the child activities and simplifies your approach to setting the desired state of the app.

To close application just call:

Otherwise due-to specific life-cycling of Android activities you can’t be sure that application is closed/killed.

whenever you are starting a new activity use

and in manifest file mention that activity as

Put this into your onClick or in onBackPressed :

What is th symptom that make you want to add an exit button ? If you need to clear the activity stack and always restart with a specific Activity, maybe you just have to tweak your activity manifest declaration with attributes like : android:clearTaskOnLaunch

Android is made in such a way that virtually NO application that was once opened, is closed.

Before mis-interpreting the statement, understand this.

«Whenever you exit your app, Android saves all the things the app was doing (called its state) and pushes the app in the background, calling the onStop() method. this is the new state of the application then, where the app isn’t running, but isn’t flushed out of the memory too. whenever you start the app again, it is resumed from the frozen state. Only when the memory, where frozen apps are kept, starts getting full, the Android GC flushes the app.»

So conceptually, nothing goes out. when you hit «back» button while ur on the first activity, Android bundles the app and data, and freezes it.

How to exit an Android app programmatically?

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 this and found calling finish() 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 Activity.moveTaskToBack(true) 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?

The finishAffinity method, released in API 16, closes all ongoing activities and closes the app:

Finish this activity as well as all activities immediately below it in the current task that have the same affinity. This is typically used when an application can be launched on to another task (such as from an ACTION_VIEW of a content type it understands) and the user has used the up navigation to switch out of the current task and in to its own task. In this case, if the user has navigated down into any other activities of the second application, all of those should be removed from the original task as part of the task switch.

Note that this finish does not allow you to deliver results to the previous activity, and an exception will be thrown if you are trying to do so.

Since API 21, you can use:

Finishes all activities in this task and removes it from the recent tasks list.

How to exit from the application and show the home screen?

I have an application where on the home page I have buttons for navigation through the application.

On that page I have a button «EXIT» which when clicked should take the user to the home screen on the phone where the application icon is.

How can I do that?

Android’s design does not favor exiting an application by choice, but rather manages it by the OS. You can bring up the Home application by its corresponding Intent:

May be you can try something like this

Suppose in our application, we have a number of activities(say ten) and we need to exit directly from this activity. What we can do is, create an intent and go to the root activity and set flag in the intent as

also, add some extra like boolean to the intent

Then in root activity, check the value of the boolean and according to that call finish(), in the onCreate() of the root activity

Is probably what you are looking for. It will close the entire application and take you to the home Screen.

This works well for me.
Close all the previous activities as follows:

Then in MainActivity onCreate() method add this to finish the MainActivity

first finish your application using method finish();

and then add below lines in onDestroy for Removing Force close

If you want to end an activity you can simply call finish() . It is however bad practice to have an exit button on the screen.

Some Activities actually you don’t want to open again when back button pressed such Splash Screen Activity, Welcome Screen Activity, Confirmation Windows. Actually you don’t need this in activity stack. you can do this using=> open manifest.xml file and add a attribute

to these activities.

Sometimes you want close the entire application in certain back button press. Here best practice is open up the home window instead of exiting application. For that you need to override onBackPressed() method. usually this method open up the top activity in the stack.

In back button pressed you want to exit that activity and also you also don’t want to add this in activity stack. call finish() method inside onBackPressed() method. it will not make close the entire application. it will go for the previous activity in the stack.
