import io.sentry.Sentry;

Sentry.init(options -> {
  options.setDsn("https://examplePublicKey@o0.ingest.sentry.io/0");

  // Set traces_sample_rate to 1.0 to capture 100%
  // of transactions for performance monitoring.
  // We recommend adjusting this value in production.
  options.setTracesSampleRate(1.0);
});
