Close To Me is an application for Android (at the moment) aimed to find new friends on Facebook using bluetooth.
You can use it to enlarge your "Graph".
Close To Me collects bluetooth name and mac address of devices it founds when makes a scan.
It is possible to make a manual scan or an automatic scan performed at regular intervals.
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.
All the information are stored inside an SQLite database.
Some simple functions to manage the database are provided.
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 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 necessary to do all the things.
Unfortunately, as far as I know, it is not possible to add a new field on Facebook's tables, and also fql queries can be perforrmed only on indexable fields.
So, to be able to find persons on Facebook, Close To Me uploads a picture of a QR barcode inside the application's album. This process returnes a unique number which will be used as the bluetooth name of the phone on which Close To Me is installed.
This unique numeber is preceded by a tag to understand that on this device is installed Close To Me.
When a new friend is found on Facebbok, it is added to the main screen and it will possible to visit its 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 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.
