Passing data through two activities?

Question

For an app I am developing, I am having the user input some information on one activity, and then on the next, the user will read something, in such that he/she won't be putting any information on it, but on the third activity, I want to display what the user put in the first. Is there a way I can carry that information from the 1st to the 3rd activity without going through the second?

You didn't google it well. See this http://stackoverflow.com/questions/5265913/how-to-use-putextra-and-getextra-for-string-data — Nabin, Aug 10 '14 at 02:04
You can use putExtra() to send something and getExtra to receive from another activity — Nabin, Aug 10 '14 at 02:05

Use sharedPreferences to store that piece of data on the phone. On the 3rd activity, read it and use it. See it here- http://developer.android.com/guide/topics/data/data-storage.html#pref

This can be done in many ways !

Why not use Intents to pass the data ?

STEP-1: <Eg:: From Activity1>

Pass the telefone into a new activity with the help of intents

Intent i = new Intent(getApplicationContext(), Activity2.class);
i.putExtra("title",telefone);
i.putExtra("descrip",telefone);
startActivity(i);

STEP-2: <Eg:: From Activity2>

Receive the string passed in another activity

Bundle extras = getIntent().getExtras();
if (extras != null) {
    String title= extras.getString("title");
    String descrip= extras.getString("descrip");
}

STEP-3: <Eg:: From Activity2> pass data again to Activity3

Receive the string passed in another activity

Bundle extras = getIntent().getExtras();
if (extras != null) {
    String title= extras.getString("title");
    String descrip= extras.getString("descrip");
}

Pass the data to Activity3

 Intent i = new Intent(getApplicationContext(), Activity3.class);
    i.putExtra("title",telefone);
    i.putExtra("descrip",telefone);
    startActivity(i);

Hope it helps ! ..........Let me know if you need more info

Use SharedPreference. Save in A1 and retrieve in A3.

Initialization

SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", 0); // 0 - for private mode
Editor editor = pref.edit();

Storing Data

editor.putBoolean("key_name", true); // Storing boolean - true/false
editor.putString("key_name", "string value"); // Storing string
editor.putInt("key_name", "int value"); // Storing integer
editor.putFloat("key_name", "float value"); // Storing float
editor.putLong("key_name", "long value"); // Storing long

editor.commit(); // commit changes

Retrieving Data

// returns stored preference value
// If value is not present return second param value - In this case null
pref.getString("key_name", null); // getting String
pref.getInt("key_name", null); // getting Integer
pref.getFloat("key_name", null); // getting Float
pref.getLong("key_name", null); // getting Long
pref.getBoolean("key_name", null); // getting boolean

Deleting Data

editor.remove("name"); // will delete key name
editor.remove("email"); // will delete key email
editor.commit(); // commit changes

Clearing Storage

editor.clear();
editor.commit(); // commit changes
