Communication via Serial between Arduino and Android phone

Hi foks,

I have made a serial connection between the pc and the Arduino Uno, now i want the same connection between a Android smartphone and the Arduino also via serial. I have looked around and there are diffrent options.

Can someone how has experience with this give me some pointers on a good approach or solution. As far as i know there is no native Android support for USB/serial connection (i could be wrong :wink: ). Can someone give me a good tip?

The data dat has to be transmitted are char buffers and structs.

Any suggestion is welcome!
