Close To Me Free

Close To Me Free is the free version of Close To Me.
It is an application for Android aimed to find new friends on Facebook using bluetooth.
You can use it to enlarge your "Graph".
Close To Me Free has limited features compared to CLose To Me. It collects only one bluetooth name of a devices it founds when makes a scan.
It is possible to make only a manual scan.
It is not necessary to be connected to Internet to make it works.
Internet is needed only to find new friends on Facebook.
So you can collect bluetooth information even where no networks are available.
After a scan, or manually, through the button on the main screen, if internet is available, the search for new friends on Facebook is performed.
Following is explained how Close To Me Free is able to find new friends on Facebook.
To avoid battery draining no bluetooth pairing is performed (also because it is not necessary), the mac address should be enough to do all the things.
So, to be able to find persons on Facebook, Close To Me Free need to record some information on an external web site (in everz moment these data can be removed).
When a new friend is found on Facebbok, it is added to the main screen and it will possible simply cliccking on his name to visit his profile and ask for friendship.
When a new friend is found a new activity feed is added to your Facebook profile (this feature can be disabled).
Close To Me Free is derived by Hackbook, it uses ZXing lib for QR barcodes. Also some pieces of code are took from BluetoothChat and from ApiDemo and many pieces of source code found on Internet.

Thanks to everybody who helped me.

Close To Me Free makes you phone visible to everybody (see below), it stores the phone name of other persons, and also your phone name will be stored on the phone of other persons.
Your phone name will remain saved inside other user's phones for a potentially infinitive time. It will be removed only if the other user decides to remove it.

Downloading and using Close To Me Free you will explicitly accept that your information will be saved on other devices. You accept also that you could be found on Facebook by persons who have this application.

There are some other important things to be noticed.
Since on Android (at least before version 4, as far as I know) it is not possible to leave your bluetooth always visible, Close To Me Free, try to enable discoverability.
If you install Close To Me Free on a rooted phone, everything will works automatically. If the phone is not rooted, Close To Me Free will ask you to enable the discoverability and it will ask every 300 seconds (I'm sorry).
As far as I know it is not possible to do it in another way. I will try to remove this big limitation if possible. There are two check boxes, the first is to enable or not the discoverability, if it is not enabled you will be able to find others but nobody will be able to find you.
The second check box is to ask to enable the discoverability in case your phone is not rooted.

Initially only few people will have this application, so, first download this free version, then buy the full version, if you want.
