the android lite replicatior always in BUSY status, can’t sync data.
after about 4 mins, the replicatior become OFFLINE → CONNECTING–> BUSY, then the data sync with sg.

Best regards!

Hi there, do you have the couchbase lite log for us? The information you provide us is not enough for us to verify the issue.

I don’t think there is much we can do about that. While I’m not sure of exactly what is going on here, when the phone is asleep, the Android OS is going to forcibly disconnect application network connections. That’s how Android works.

HI @Sandy_Chuang @blake.meike,

thanks for your reply. I’ll find a method to keep the application network keepalive.

Best Regards!
