Checked out SharedPreferences. Some examples here: SharedPreferences Tutorial

If you only have one user at once and just need to store simple user data like user name, email, id, you can store string/int/... format data in it. Or if you have server for storing user data, you can store credentials in SharedPreference and use the credentials to get data from your server.

I suggest you use SharedPreferences, unless you have a lot of information to store. After the user successfully logged in, store his information in your Preferences.

For example, to store the username :

private SharedPreferences mPreferences;

mPreferences = getSharedPreferences("User", MODE_PRIVATE);
SharedPreferences.Editor editor = mPreferences.edit();
editor.putString("username", your_user_name);
editor.commit();

Each time the user accesses the login activity, you can check if the username is already stored in the preferences :

if (mPreferences.contains("username")) {
    // start Main activity
} else {
    // ask him to enter his credentials
}

When the user logs out, don't forget to delete the username key from your preferences :

SharedPreferences.Editor editor = mPreferences.edit();
editor.clear();   // This will delete all your preferences, check how to delete just one
editor.commit();

Insert the data to a SQLite database or use a plain file. The former is recommended for big apps.
