Hi

How much experience do you have with Android app development?

Have you downloaded the source code for the Android-nRF-Blinky app?

The existing button is defined in the activity_blinky.xml file. Look for the Switch with ID "led_switch", and make another one with a different ID. You will also need to change the layout constraints to define where on the screen the switch should be placed, otherwise it will be placed on top of the existing switch. 

Then you should go to BlinkyActivity.java and add some code for responding to input from the switch. Look at how the Switch mLed variable is handled in the code, and do something similar for your new button. 

Best regards
