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
HttpLoggingInterceptor logging = new HttpLoggingInterceptor(new Logger() {
  @Override public void log(String message) {

 * until [nextPart] returns null. After calling [nextPart] any preceding parts should not be read.

 * Typical use loops over the parts in sequence:
 *
 * ```kotlin
 * val response: Response = call.execute()
