The Sentry Java SDK can be used with Kotlin, Scala, and other JVM languages. Code examples are typically provided in both Java and Kotlin.

On this page, we get you up and running with Sentry's SDK.

Sentry captures data by using an SDK within your application’s runtime.

plugins {
  id "io.sentry.jvm.gradle" version "4.4.1"

Configuration should happen as early as possible in your application's lifecycle.

import io.sentry.Sentry;

Sentry.init(options -> {

  // Set traces_sample_rate to 1.0 to capture 100%
  // of transactions for performance monitoring.
  // We recommend adjusting this value in production.

This snippet includes an intentional error, so you can test that everything is working as soon as you set it up.

import io.sentry.Sentry;

try {
  throw new Exception("This is a test.");
} catch (Exception e) {

To view and resolve the recorded error, log into and open your project. Clicking on the error's title will open a page where you can see detailed information and mark it as resolved.
