Intermittent connections with android and phonegap

[Daniel Carr]

Hi all. 

I'm finding that a couchbase-lite android app (on phonegap) is having it's pull replications fail silently.  I had a simultaneous push replication working fine. 

I've got 3 questions here. 1) is a continuous replication supposed to stay alive no matter what? (In couchdb, by default it tries 10 times then dies.)   2) how do I know if it's died?  3) How likely is it the liteServer that's the problem here, and would I be better off handling the replications in java?

What I did: 

*  start a continuous pull replication (POST to /_replicate)

*  turn off wifi

*  wait on hour

*  turn on wifi

What I observed:

*  GET /_active_tasks returns the replication info with no error.

*  any changes made on the server have not been replicated.

*  after restarting the application, the replication works.

The only unusual thing in the logs is a few of these:

Thanks for reporting, that sounds like a bug.  Can you file an issue here: https://github.com/couchbase/couchbase-lite-java-core and include:

* The version of couchbase lite you are using (or phonegap plugin), with a download link where you downloaded it.

* Links to logcat logs (posted on github gists or pastebin)

* Anything else you can think of that will help reproduce the issue.
