Using LTS Android Studio, I made an app with the SDK of Android 5.0. I connected the app with Firebase but on step 2 of "Add FCM to your app", does not work. In fact, it does not do anything.
Trying to add implementation 'com.google.firebase:firebase-messaging:23.0.8' on build.gradle, doesn't help either. Throws a compilation error. I have to use classpath 'com.google.firebase:firebase-messaging:23.0.8' for it to compile properly, but when I launch the notification on Firebase, it does not receive it.
I indeed added the Internet permission on the manifest. Doesn't work either.
Any help is appreciated.
Edit: I was adding the library to the wrong place + Firebase takes some minutes to send the notification.
