This is really wierd issue I have!!
My app with firebase notifications.
I am testing it between two phones: xperia e4g(api 19) and xperia z3(api 23)
Notifications work when( notification received on target device)
Sent through fb panel: both api19 and api23
Sent by phone to debug version of app : both api19 and api23
3.sent by phone to release version installed manually on device: both api19 and api23
- Sent by phone to release version installed from google play: only api19
Notifications does not work when: 1. Sent by phony to release version installed from google play: only api23
Very thanks for help! The main frustrating thing that- one app code behavior is different on two devices...
Addon: googleplay services checked on z3(API19) and work correctly
Addon : onMessageReceived Service is not react neither back nor fore ground mode of APP:
Addon : Tested same code on API 16 Samsung GT-N7000 - notifications work good.
Addon: proguard rules case tested ( with and without firebase exclusions)
Current status of issue: two way - particular device has some internal gap exactly for my app (fantastic!) or API 23 has gap exactly for my app (fantastic still).
