I face this problem in two android projects . In one i was trying to retrieve data from Firebase into Recyclerview and in onother i was trying to login using phone number but in both cases logcat is showing V/FA:
Inactivity, disconnecting from the service
Inactivity, disconnecting from the service
You Need to follow few steps to remove this problem.
Reason: You face this problem because in the background there are few-thread and the process is running in the android studio which uses the connection of firebase and your process not get the connection.
Steps:
It takes few mints and restarts you android studio and that error is gone. Because all the backend thread and process are closed.
Happy Coding.
