"java.security.AccessControlException: access denied" while connecting google CCS

Question asked by singale on Oct 14, 2014

Hello,

 

I  have followed the tutorial at the link https://developer.android.com/google/gcm/ccs.html#implement.

I am using Smack 4.0.4.

I have created an endpoint for the method "connect" and deployed this class on google app engine.

However when I call "connect" from my android mobile client app, i get exception as shown below.

What does this exception mean?

Any helpful comment is appreciated!

WARNING: Cannot connect to CCS server.
