  <pre><code>private String getAccessToken() {
      try {
          Log.e("tree","get access entered");
          javax.ws.rs.client.Client client = javax.ws.rs.client.ClientBuilder.newClient();
          javax.ws.rs.client.Entity&lt;String&gt; payload =
                  javax.ws.rs.client.Entity.text("grant_type=client_credentials&amp;redirect_uri=https://facebook.com/__");
          javax.ws.rs.core.Response response = client.target("https://v2.api.xapo.com/oauth2/token")
                  .request(MediaType.TEXT_PLAIN_TYPE)
                  .header("Authorization","Basic ___")
                  .post(payload);
  Log.e("tree","response completed");
              String body = response.readEntity(String.class);
              Log.e("tree","body "+body);
          } catch(Exception e) {
  Log.e("tree","token exception "+e.getMessage());
          }
