Currently the integration test is failing due to a backend error (1) and additionally another bug has been found in the SDK (2). It is worth mention they are already known and that a workaround exists.

1. From the server side (aerogear-app-metrics) there's a limitation for the size of field "clientId" that makes the server returns an Internal error:

{

    "error": "Internal Server Error",

    "message": "Internal Server Error",

    "statusCode": 500

}

From the client side there is (likely) a bug that triggers a NPE, in NetworkMetricsPublisher , httpResponse.getRequestError() returns null.
