How to launch preference screen in preference android
<p>the question is - how can I launch another preference screen in preference android ,
I have used the following code :</p>

<pre class="lang-java prettyprint-override"><code>@Override
    public boolean onPreferenceTreeClick(PreferenceScreen preferenceScreen,
            Preference preference) {
        Log.d("prefs", preference.getKey());
        String text = preference.getKey();
        if (text.equals("call")) {

            startActivity(new Intent(this, prefs_Call.class));
        }
        return super.onPreferenceTreeClick(preferenceScreen, preference);
    }
</code></pre>

<p>but it is not working as <code>prefactivity</code> can not launch this intent  , How ?</p>
