hi, thanks for the answer, found your thread earlyer! I’m strugglig for days now with no succes. Now i read that i need to try the speed 57600. I will try it tomorrow. In my example the app just exits with no error message. Thanks again for the fast response! 
Hi!
I’ve tried your example code, changed the Manifest file, added the device_filter.xml in the root/res/xml.
Uploaded the sketch without any error. Now when i plug my arduino nano to the phone it suggest me the sketch to start, thats seems good, but after that it just exits without any reason or error message. Tried another android device, same issue. Did i miss something?

the chip is CH340G, my android support otg, tested with a wiresless keyboard with touchpad, and it works well.
Hi
I have tested it with Atmega16u2 only

the keyboard i used has an USB receiver plugged to the android device through OTG cable. The arduino chip is ATMEL M328P. Release 0.1.0-alpha · inventit/processing-android-serial · GitHub thats the link to the library.
yes The arduino chip is ATMEL M328P. but i used the one with Atmega16u2 usb driver not the CH340G chip

that would be great!
i’ve installed the app ‘serial USB terminal’ on the android device, and it sees the arduino board, so i think the physical connection is working well.
hi
i have not test yet but for now try to change device_filter.xml with this and inform what you got
