(JAVA) Google API - unable to obtain new “access token” using “refresh token

[xoip]

I want to obtain a new "access token" based on the "refresh token" saved in database for Google API Analytics.

Here is the code I wrote:

GoogleCredential.Builder credentialBuilder = new GoogleCredential.Builder()
        .setTransport(HTTP_TRANSPORT).setJsonFactory(JSON_FACTORY)
        .setClientSecrets(CLIENT_ID, CLIENT_SECRET);
credentialBuilder.addRefreshListener(new MyCredentialRefreshListener());

credential = credentialBuilder.build();
credential.setRefreshToken("saved_refresh_token_from_database");

try {
    credential.refreshToken();
} catch (IOException e) {
    e.printStackTrace();
}


class MyCredentialRefreshListener implements CredentialRefreshListener {
    public void onTokenResponse(Credential cr, TokenResponse tr) {
       System.out.println("Credential was refreshed successfully.");
    }

    public void onTokenErrorResponse(Credential cr, TokenErrorResponse tr) {
        System.out.println(tr);
    }
 }

I get this message:

com.google.api.client.auth.oauth2.TokenResponseException: 400 Bad

Request { "error" : "invalid_grant" }

I use the same CLIENT_ID, CLIENT_SECRET and "refresh token" in a php script and there I managed to get the new "access token" using "refresh token" when "access token" expired.

I wrote the code based on javadoc.google-oauth-java-client.

Any person here knows how to modify the code to obtain the new access token ?

Thanks in advance.
