App isn’t closed when coming notification, FCM service is running on background. You can select your app in “choose process” screen on android studio.

Just log incoming message to Logcat

if you want to wait for debugger, and cold start of the app (so app is not started yet) just use
android.os.Debug.waitForDebugger()

Send notification to yourself while app is closed and FCM Service start to running on background in this moment. You can select your app in “choose process” screen

True, but it may be tricky to catch particular moment between app start and moment when you attach it to debugger, waitForDebugger() may help debug such cases

In my case, App will stop at breakpoint while you click to notification.

yes, but it only if you debug some code that runs after click
you may also want to debug code that parses GCM message or register InstanceId token etc, really depends on case
