The APP closed unexpectedly always.
Hello guys. I have like a 1 week trying to follow the video tutorial, I do not get any error, just for the issue that when I "run" or "Debug" the APP, the app open in my cellphone normally, but when I push a custom button that I add as the exercise indicated, the APP always closed unexpectedly.
My cellphone is a brand new Motorolla X Play.
I followed the video tutorial several times, step by step, and the result is always the same, APP Closed unexpectedly, and I am sure I have No errors in the code.
What can I do?
