Guys, I finally found the root cause of this error!! It’s because MobileAds.initialize() is in MyApplication’s onCreate(). When push notification is received, FirebaseMessagingService class will be called -> MyApplication will also be created. -> MobileAds.initialize() is then executed on the main thread.

If MobileAds.initialize() take too long to complete(especially in slow devices), ANR will happen, while the app is actually in the background!

Official document from Admobs says Before loading ads, have your app initialize the Mobile Ads SDK by calling MobileAds.initialize() which initializes the SDK and calls back a completion listener once initialization is complete (or after a 30-second timeout). This needs to be done only once, ideally at app launch.

Don’t trust them.

I faced the same problem, tested different libraries for a month. All firebase libraries half a year old work without ANR, but all the latest versions (in particular, performance) produce a lot of ANR
