Answer 2

SharedPreferences may be the easiest way in your case. This is designed for storing a relatively-small amount of data (ballpark practical maximum around 50-100 values) in classic key/value format.

You could use SharedPreferences.

import android.content.SharedPreferences;

...

private SharedPreferences mPrefs;

private static final String MY_TEXT_BOX_STRING_KEY = "prefs_textbox_key"

...

mPrefs = getSharedPreferences("myAppPrefs",0);

...

// Get the string:

myTextBoxString = prefsGetString(MY_TEXT_BOX_STRING_KEY);

// Set the string:

prefsSetString(MY_TEXT_BOX_STRING_KEY, "blahblah");
