I created a Roll dice app following the Google introduction course to Kotlin. I am now implementing Firebase Analytics to track each dice rolled.
- I followed Firebase instructions to install Firebase SDK within my gradle files.
- I followed Google instruction to implement event tracking
- I entered the 3 adb commands to see my log events in the Android Studio Logcat tab
But, I don′t know why my events aren't logged, they don't appear in my Logcat tab... When I initialize my app I can see various Firebase logs, but then when I click the button for which I have an event, Firebase doesn't log it. I checked my code and I don′t think problem comes from here.
Someone to help me?
I share with you my code and all messages I have in my terminal and catlog tabs.
