Android intents are launched in reverse order

I am working on an android app where I from one activity create and start a number of activities using intents (and close these using the finish() method()) however when I run the app the order the activities are launched in is the reversed of the creation order. I realize this is because the intents are not launched imminently on the startActivity(Intent) call, but added to a queue, but I would really like to preserve the order. My question is, is there any way to keep the order of the activities as they are created? See pseudo code for better explanation
**Main Class**
Intent intent1 = new Intent(this, activity1);
startActivity(intent1);
Intent intent2 = new Intent(this, activity2);
startActivity(intent2);
Intent intent3 = new Intent(this, activity3);
startActivity(intent3);
**Intent class**
....
finish()
However when I launch the app the activity 3 is launched first, followed by 2 and finally 1 ---> how do I preserve the order so they launch 1->2->3?
Thanks a lot in advance

You can start first activity, in it's onCreate(...) method start second and then in onCreate(...) of second activity start third. So you will get 1->2->3 and 3 will be on the top of the stack

Finish all activities inside Preference Activity

I have a PreferenceActivity with a custom DialogFragment for clearing the app data, so I want it when the user clicks Yes, the application to either close completely (finish all activities) or just to tell it to go to the InitialSetup activity, so the app ca be set up again anew. So far I havent been able to do it in any way...
Tried with
Intent intent = new Intent(context.getApplicationContext(), MySettings.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
context.startActivity(intent);
but that still does not close all the activities in the back stack...
How can I do it?

What you need is FLAG_ACTIVITY_CLEAR_TASK and FLAG_ACTIVITY_NEW_TASK flags for your intent:
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
Or as mentioned Sartheris use IntentCompat for Android APIs below 11:
Intent intent = IntentCompat.makeRestartActivityTask(new ComponentName(context, MySettings.class));
startActivity(intent);

If you only want the app to close, with the user having to start it again later, you can use
System.exit(0);
as you would in ordinary Java.
If you want your app to restart automatically after it's closed, use a PendingIntent as the answer for this question does:
how to programmatically "restart" android app?

reopen app from background

When user press "Home Button" my app go to Background, but is still running. I need bring my app to front again. For example i've this code:
Context ctx=getApplicationContext();
Intent i =ctx.getPackageManager().getLaunchIntentForPackage("com.example.test");
ctx.startActivity(i);
but this code is to open app in different activity, there are a method or something to do this "correctly"?

You can simulate the "launching" of the app the same way that Android launches the app when the user selects it from the list of available apps. If the user starts an application that is already running, Android just brings the existing task to the foreground (which is what you want). Do it like this:
Intent intent = new Intent(context, SplashScreen.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // You need this if starting
// the activity from a service
intent.setAction(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
startActivity(intent);
(Source: https://stackoverflow.com/a/12075313/3529926)

You can set this flag to your intent
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
and set the launch mode of your activity to single task in manifest (add this is your activity tags):
android:launchMode="singleTask"

Closing an android application programatically in android

I have a application that has two activities
Activity1
Activity2
Now i start Activity1 and move to Activity2 now i want to close the application at a moment
If i use finish() i am able to close only Activity2 and not
Activity1
What i want to do ::
i want my application to quit(close all activities and go to
homescreen)
But i don't want my apk to be removed from android system itself
How can i achieve this ?
{Edit}
I used the code(Activity2 has a fragment which launched a dialog on
"ok" condition in positive condition i am performing this condition below)
I am able to launch the previous activity but it is not canceled, its
just reloaded
Intent intent = new Intent(getActivity(), SplashActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
getActivity().finish();

You need to make your Activity2 as "top task" with a Flag when you call it as follows:
Intent intent = new Intent(Activity1.this, Activity2.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
See the Reference:
If set in an Intent passed to Context.startActivity(), this flag will cause any existing task that would be associated with the activity to be cleared before the activity is started. That is, the activity becomes the new root of an otherwise empty task, and any old activities are finished.
Then, call finish() in your Activity2. This should do the trick.

There is a way to kill your application process, but it is not recommended
this.finish();
Process.killProcess(Process.myPid());
This will kill your application and releases all the memory associated with it.
Note: Assuming your app has a single process id

Do like this
Intent intent = new Intent(Activity1.this, Activity2.class);
startActivity(intent);
Activity1.this.finish();

Intent intObj=new Intent(this, Homescree.class);
intObj.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_CLEAR_TASK |
Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intObj);

Clearing all activities in android

I have 4 Activities 1.Home,2.B,3.C and 4.D. Whenever I start Home from Activity D I want to finish all other activities. I Used this code, but when I press back button from Home it brings me to the previous activity. What I did wrong here.?
Intent intent = new Intent(getApplicationContext(), Home.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent)

You can try this,
Intent intent = new Intent(getApplicationContext(), Home.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
Note: As described in FLAG_ACTIVITY_CLEAR_TOP documentation
This launch mode can also be used to good effect in conjunction with FLAG_ACTIVITY_NEW_TASK: if used to start the root activity of a task, it will bring any currently running instance of that task to the foreground, and then clear it to its root state. This is especially useful, for example, when launching an activity from the notification manager.

intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
This will work only for activities which are still in the activity stack. I believe you are finishing the Home Activity when going to B. So that CLEARTOP won't work.
Now try something like this.
You need to set an Extra with intent Of "D" to Home. Then you have to check the Intent extra in Home, call finish() if the extra matching
Intent intent = new Intent(contxt, Home.class);
intent.putExtra("urString",defaultvalue);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
// Checking the intent extra at "HOME"
if(getIntent().hasExtra("urString")){
// manage your own way
finish();
}

In manifest.xml file set android:nohistroy="true" for all the activities
