App crashes/ implementing picture in picture mode to timer
+0
−2
When I tried to emulate the app that I coded in the connected phone, it keeps closing due to crashes, is there any problem with my code?
Also, I am trying to make a timer app with picture and picture mode. I followed the tutorials and try to combine these:

It works individually but when I tried to combine them, it does not work.
