Getting http 404 error in android simulator for couch base lite during replication

In my Mac 10.9.2 I installed couch base server and it is running on http://127.0.0.1:8091 It has it's default buckets including beer-sample

I started sync server as

./sync_gateway -bucket="beer-sample"

that logs following in console

14:00:55.903306 ==== Couchbase Sync Gateway/0.94 ====

In android my replication code looks like

Replication pullReplication = database.createPullReplication("http://10.0.2.2:4984");
pullReplication.start();

Then i ran my android app in simulator and i logged error as in changeEventListener

        if (!replication.isRunning()){
            Log.d(TAG, "Replication is not running due to " + replication.getLastError().getMessage());
            Log.d(TAG, "Replication is not running due to " + replication.getLastError().getCause());
            Log.d(TAG, "Replication is not running due to " + replication.getLastError().getStackTrace());
            Log.d(TAG, "Replication is not running due to " + replication.getLastError().toString());
        }

that logged

Note: I am using 10.0.2.2 instead of 127.0.0.1 because i read in forum that's how simulator maps the host machine. But i also tried 127.0.0.1 earlier which also gives the same result.

At the same time i am seeing in sync gateway console log a new entry like

14:05:13.532393 HTTP:  #006: GET /_changes?feed=normal&heartbeat=300000

I tried to repeat this query in a browser like

> http://127.0.0.1:4984/_changes?feed=normal&heartbeat=300000

which is showing

{"error":"not_found","reason":"unknown URL"}

What is the mistake i am doing here? I am new to couch base.

Solution

Managed to get past this error:

Found a reference project in https://github.com/couchbaselabs/GrocerySync-Android

Key changes made to my original steps/code are

Executed sync gateway as ./sync_gateway -bucket="beer-sample" -url=“http://localhost:8091/beer-sample" -verbose
added database in the Sync URL like "http://10.0.2.2:4984/beer-sample" i.e., database.createPullReplication("http://10.0.2.2:4984/beer-sample");
Ran into authorization error. To let anonymous access (for the time being) enabled GUEST account by executing below command in terminal

curl -X PUT localhost:4985/beer-sample/_user/GUEST --data '{"disabled":false, "admin_channels":["public"]}'
