Sentry's Java SDK enables capturing sessions for Release Health as well as reporting messages and errors.
Sentry for Java is a collection of modules provided by Sentry; it supports Java 1.8 and above. At its core, Sentry for Java provides a raw client for sending events to Sentry. To begin, we highly recommend you use one of the logging libraries or framework integrations.
On this page, we get you up and running with Sentry's SDK, so that it will automatically report errors and exceptions in your application.
If you don't already have an account and Sentry project established, head over to sentry.io, then return to this page.
Using a framework or logging library? Take a look at our specific guides to get started.
Install
Sentry captures data by using an SDK within your application’s runtime.
build.gradle// Make sure jcenter or mavenCentral is there.
repositories {
jcenter()
// Or
mavenCentral()
}
// Add Sentry's SDK as a dependency.
dependencies {
implementation 'io.sentry:sentry:3.1.0'
}Configure
Configuration should happen as early as possible in your application's lifecycle.
import io.sentry.Sentry;
Sentry.init(options -> {
options.setDsn("https://examplePublicKey@o0.ingest.sentry.io/0");
});Verify
This snippet includes an intentional error, so you can test that everything is working as soon as you set it up:
import java.lang.Exception;
import io.sentry.Sentry;
try {
throw new Exception("This is a test.");
} catch (Exception e) {
Sentry.captureException(e);
}Or, by manually generating an event:
In Java you can capture any exception object that you caught:
import io.sentry.Sentry;
try {
aMethodThatMightFail();
} catch(Exception e) {
Sentry.captureException(e);
}Learn more about manually capturing an error or message, in our Usage documentation.
To view and resolve the recorded error, log into sentry.io 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.
