firebase offline-online somethings

Now try to use firebase for design app. But get somethings about :

1. At offline, you can read, but add, delete, edit can not, this "can not" is snapshot that need to online sync, then get data.

2. So firebase example is use models or objects to keep data, but you change activeity or clearn app, then objects data loss. maybe can use Serialization, but not good idea.

3. Can't control local database. This is fun, maybe firebase no local database or other methods for offline. Some app need offline, for  counting data, CURD data, keep then sync, counting age.

mm, I think my java, android app and firebase knowledge, I don't real understand or think error. So just writer this message for keep.

1、sudo /etc/init.d/couchbase-server stop


or Linux 2.0 this is /opt/couchbase/var/lib/couchbase/ip. This file contains the identified IP address of the node once it is part of a cluster. Open the file, and add a single line containing the hostname, as configured in the previous step.

For Linux 2.0.1. You update the ip_start file with the hostname. The file is at this location: /opt/couchbase/var/lib/couchbase/ip_start.


Delete the files under:

/opt/couchbase/var/lib/couchbase/data/*
/opt/couchbase/var/lib/couchbase/mnesia/*
/opt/couchbase/var/lib/couchbase/config/config.dat


Execute:

sudo /etc/init.d/couchbase-server start

=======================
If can't not, maybe reinstall. just delete 
/opt/couchbase/var/lib/couchbase/config/config.dat

then server stop, restart. then can resetup.
