Please get a client id for your app from the paypal. Following link has the details the way to get a client id.Then replace it for the id of the following line of your code base.

private static final String CONFIG_CLIENT_ID = "id";

You might have already solved this, but just so you know I encountered the same error response before. My issue was that the the currency for the registered business entity and the android app currency settings was different.
