Access to SharedPreferences from different activity
<p>In first (MainActivity) I save data trough SharedPreferences:</p>

<pre><code>Editor editor = mGameSettings.edit(); 
                editor.putString(GAME_PREFERENCES_SHOP, Shops.get(lv.getCheckedItemPosition())); 
                editor.commit();
</code></pre>

<p>And I can read this data from MainActivity after restart application:</p>

<pre><code>if (mGameSettings.contains(GAME_PREFERENCES_SHOP)) 

                Tv2.setText(mGameSettings.getString(GAME_PREFERENCES_SHOP, ""));
</code></pre>

<p>But how to read and edit this SharedPreferences from other activity?</p>
