Da /data/data/com.facebook.orca/databases/users_db2
oppure /data/data/com.facebook.katana/databases/contacts_db2

1. Lista degli amici (incluso il proprio account) e id degli utenti, il campo non ha indici quindi 
   non e' immediato capire quando la lista viene modificata:

	select fbid, first_name, last_name, name, email_addresses, phone_numbers from facebook_users
	
	fbid			first_name	last_name		name					email_addresses						phone_numbers
	100003663718866	Antroide	Succhienmberg	Antroide Succhienmberg	"[""test.ardissimo@gmail.com""]"	[]
	100003727657439	Daniel		Paton			Daniel Paton			"[""dannyp1690@yahoo.co.uk""]"		[]
	100003791528612	Jill		Jones			Jill Jones				"[""jillyj1212@hotmail.com""]"		[]
	100004427018593	Gäjendra	Kumär			Gäjendra Kumär			[]									"[{""full_number"":""+918870723382"",""display_number"":""+918870723382"",""android_type"":2}]"

2. Da threads_db o threads_db2 Estrarre le conversazioni (timestamp = markup), se timestamp_ms non va si puo' provare con last_fetch_time_ms:

	select thread_id, participants from threads where timestamp_ms > 0
	
	thread_id				participants
	t_id.392941390796027	"[{""email"":""1398126113@facebook.com"",""user_key"":""FACEBOOK:1398126113"",""name"":""Faber O'Connell"",""mute"":0,""lastReadReceiptTimestampMs"":1359458980898},
							{""email"":""100003663718866@facebook.com"",""user_key"":""FACEBOOK:100003663718866"",""name"":""Antroide Succhienmberg"",""mute"":0,""lastReadReceiptTimestampMs"":0}]"
	t_id.326617500782882	"[{""email"":""1398126113@facebook.com"",""user_key"":""FACEBOOK:1398126113"",""name"":""Faber O'Connell"",""mute"":0,""lastReadReceiptTimestampMs"":1359459240118},

							{""email"":""1449558658@facebook.com"",""user_key"":""FACEBOOK:1449558658"",""name"":""Alberto Ornaghi"",""mute"":0,""lastReadReceiptTimestampMs"":1359459183374}]"

    [{"email":"1398126113@facebook.com","user_key":"FACEBOOK:1398126113","name":"Faber O'Connell","mute":0,"lastReadReceiptTimestampMs":0},
    {"email":"802840113@facebook.com","user_key":"FACEBOOK:802840113","name":"Alberto 'Q' Di Paolo","mute":0,"lastReadReceiptTimestampMs":1363787970464},{"email":"1449558658@facebook.com","user_key":"FACEBOOK:1449558658","name":"Alberto Ornaghi","mute":0,"lastReadReceiptTimestampMs":1363788003630}]
	
3. Estrarre il testo di ogni conversazione, essendo noti i partecipanti sappiamo il sender (dalla query) e quindi chi riceve i messaggi,
   il thread_id e' estratto dalla query 2.:

	select text, sender, coordinates from messages where thread_id == 't_id.392941390796027' and text != ''
	
	text		sender																															coordinates
	Pistola!	"{""email"":""1398126113@facebook.com"",""user_key"":""FACEBOOK:1398126113"",""name"":""Faber O'Connell""}"	
	Frocismo	"{""email"":""100003663718866@facebook.com"",""user_key"":""FACEBOOK:100003663718866"",""name"":""Antroide Succhienmberg""}"	"{""latitude"":45.4764059,""longitude"":9.1911257,""accuracy"":40.0,""altitude"":0.0,""heading"":0.0,""speed"":0.0}"

4. Ottenere il proprio id, da prefs_db:

	select value from preferences where key = '/auth/user_data/fb_me_user'
	
	value
	{
   "uid":"100003663718866",
   "first_name":"Antroide",
   "last_name":"Succhienmberg",
   "name":"Antroide Succhienmberg",
   "emails":[
      "test.ardissimo@gmail.com"
   ],
