Hi everybody,
I am new to the forum.
I have written a small app that uses two buttons to turn ON and OFF two
LEDs.
It compiles with no errors.
The console says it was installed on my tablet correctly...but then it
crashes when run.
Can someone take a look at the code below and help me, please?
By the way I am new to Java and android!
Regards
