In the Android studio (or eclips) we can turn on or off the LEDs using "libFriendlyarm-Hardware.so". :ugeek:

We want to control a button connected to EINT-8 or EINT-15. we couldnt do that.

(in other words; We could not use gpio on 4412-1506.
We could not turn on a LED connected to the GPIO or As I said above)

Please help us in this regard. thank you.
