问题
I need to establish communication between two android phones (same application, if it matters).
Is there any possibility for android applications to establish a data stream via bluetooth (so there is no need for internet connection)?
Or (UDP)TCP/IP over internet is currently best solution?
回答1:
Since Android 2.0 it should be possible to use the bluetooth API (see here).
回答2:
In android 1.5, i believe, there's no file transfer via bluetooth. In order to be version agnostic, bump transfers all the data via their servers i believe.
