```java
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(Level.BASIC);
OkHttpClient client = new OkHttpClient.Builder()
  .addInterceptor(logging)
  .build();
```

You can change the log level at any time by calling `setLevel()`.

To log to a custom location, pass a `Logger` instance to the constructor.
```java

public final class LoggingInterceptors {
  private static final Logger logger = Logger.getLogger(LoggingInterceptors.class.getName());
  private final OkHttpClient client = new OkHttpClient.Builder()
      .addInterceptor(new LoggingInterceptor())
      .build();

  public void run() throws Exception {
    Request request = new Request.Builder()
        .url("https://publicobject.com/helloworld.txt")
        .build();

  @Test
  fun testHttpLoggingInterceptor() {
    val interceptor =
      HttpLoggingInterceptor().apply {
        level = HttpLoggingInterceptor.Level.BASIC
      }

    val client = clientBuilder.addInterceptor(interceptor).build()

    try {
      client.newCall(request).execute()
    } catch (uhe: UnknownHostException) {
      // expected
    }

    val logs = ShadowLog.getLogsForTag(AndroidPlatform.Tag)
