}die spotify.spotifyhttpManger.execute Klasse lookes wie diese
private String execute(HttpMethod method) throws WebApiException, IOException {
final HttpClient httpClient = new HttpClient(connectionManager);
try {
httpClient.executeMethod(method);
handleErrorStatusCode(method);
String responseBody = method.getResponseBodyAsString();
handleErrorResponseBody(responseBody);
return responseBody;
} catch (IOException e) {
throw new IOException();
} finally {
method.releaseConnection();
}
}ich keine idear haben, warum ich diesen Fehler Erz haben, wie es zu beheben atm keine idears?
