Figured it out - below is a sample to add a custom User-Agent in any HTTP request using `PreprocessHttpRequestCallback` in Java. `customValue` should be replaced with the preferred User-Agent string.

Note: there was a bug in our old Android player SDK (\< 3.17.0) which was the User-Agent overwrite was ignored as described in our release note ([Bitmovin Docs - Player Android / AndroidTV Release 3.17.0](https://bitmovin.com/docs/player/releases/android/android-3-17-0)). So ensure to use version 3.17.0 or later.

```java
NetworkConfig networkConfig = new NetworkConfig();
PreprocessHttpRequestCallback preprocessHttpRequestCallback = new PreprocessHttpRequestCallback() {
    @Nullable
    @Override
    public Future<HttpRequest> preprocessHttpRequest(HttpRequestType httpRequestType, HttpRequest httpRequest) {

        ExecutorService executorService = Executors.newSingleThreadExecutor();
        Callable<HttpRequest> callable = () -> {
            HashMap<String, String> headers = new HashMap<>();
            headers.put("User-Agent", "customValue");
            httpRequest.setHeaders(headers);
            return httpRequest;
        };
        Future<HttpRequest> future = executorService.submit(callable);
        return future;
    }
};
networkConfig.setPreprocessHttpRequestCallback(preprocessHttpRequestCallback);
player.getConfig().setNetworkConfig(networkConfig);

```
