Find class to use with ComponentName class in Android

I have a single widget that call another application, here is the most important part of the code:

final Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
final ComponentName cn = new ComponentName("com.android.settings", 
"com.android.settings.wifi.WifiSettings");
intent.setComponent(cn);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
ctxt.startActivity( intent);

The important part is

final ComponentName cn = new ComponentName("com.android.settings", "com.android.settings.wifi.WifiSettings");

This call the wifi settings in android, but I found this code in a web site, I want to know how I can call the data roaming and other settings in the system, where I can see this?

com.android.settings is the name of the package. If you go here you can find all the settings available in this package. The roaming settings are in package com.android.phone - see here.

EDIT : it appears that using package names is not portable. Your best bet is to use :

startActivity(new Intent(Settings.ACTION_DATA_ROAMING_SETTINGS));

The list of intents is in the Settings class

You may also need to add FLAG_ACTIVITY_NEW_TASK to your intent
