Working code to send file from Android to any phone ?

[kInG aLeXo]

I am looking for a code to send files from an anrdroid phone to other phones. I found several codes online but none of them seemed to really work. Most codes I found were very similar to this which just does not nothing at all when executed (after I replace the destination with my other mobile bluetooth address).

Only thing that I found it working was lanuching content provider, and letting the user explicitly choose Bluetooth.

Is there a way to immediately launch the bluetooth application given a file name, instead of letting the user choose between several available applications ?
