Welcome page for Android App

Question

I am new to android development, and developing a small app for practice purposes. I want the following: When the user installs the app, he/she is greeted with a set of welcome pages, that give details about the app, and then proceeds to the actual app. But I don't want that set of pages to appear anytime after the first time the app is opened. So how do I go about implementing that?

PS: This is my first question posted, excuse typos or brevity if any.

Edit: It seems like there is another question of the same context, but I also want to know how to make such an activity that will load only once after the installation.

What have you researched or tried so far? What are your current ideas? — Mehmet K, Feb 07 '17 at 14:56
start android from this site - https://developer.android.com/training/basics/firstapp/index.html, https://developer.android.com/training/index.html, and some like http://www.androidhive.info/, etc — Rehan Shikkalgar, Feb 07 '17 at 15:00

@cricket_007 Yes but it answers only a part of question, I also want to learn to make an activity that will appear only once after installing. — Varun Rao, Feb 07 '17 at 15:46
You just call `startActivity` when your boolean flag is true, otherwise dont — OneCricketeer, Feb 07 '17 at 15:55
@howdoidothis I think I will have to use intents, but was not sure about the SharedPreferences — Varun Rao, Feb 07 '17 at 15:55

You can achieve this result in different way, one of them may be to store on SharedPreference

isFirstLoad = true

after the user read you intro page then

isFirstLoad = false

in your main activity check for first load to redirect user to correct activity

Intent i = ...// normal activity
if(isFirstLoad){
    i = ...// intro activity
}
startActivity(i);

you should use SharedPrefrences for store that it is the first time or not. you can creat a class for store information like this.

public class prefrence
{
    SharedPreferences sharedPreferences;
    public prefrence(Context context)
    {
        sharedPreferences = context.getSharedPreferences("myAppData", 0);
    }

    public boolean isFirstTime()
    {
        return sharedPreferences.getBoolean("first", true);
    }

    public void setFirstTime(boolean b)
    {
        sharedPreferences.edit().putBoolean("first", b).commit();
    }

}

and check that it is first time or not like this:

if (new preference(context).isFirstTime()) {
    showSplash();
    new preference(context).setFirstTime(false);
}
