## Getting started

In your `build.gradle`:

```groovy
dependencies {
  debugImplementation 'com.squareup.leakcanary:leakcanary-android:1.6.2'
  releaseImplementation 'com.squareup.leakcanary:leakcanary-android-no-op:1.6.2'
  // Optional, if you use support library fragments:
  debugImplementation 'com.squareup.leakcanary:leakcanary-support-fragment:1.6.2'
}
```

In your `Application` class:

```java
public class ExampleApplication extends Application {

  @Override public void onCreate() {
    super.onCreate();
    if (LeakCanary.isInAnalyzerProcess(this)) {
      // This process is dedicated to LeakCanary for heap analysis.
      // You should not init your app in this process.
      return;
    }
    LeakCanary.install(this);
    // Normal app init code...
  }
}
```

**You're good to go!** LeakCanary will automatically show a notification when an activity or support fragment memory leak is detected in your debug build.

**What's next?** You could watch a [live investigation](https://www.youtube.com/watch?v=KwArTJHLq5g) then [customize LeakCanary](https://github.com/square/leakcanary/wiki/Customizing-LeakCanary) to your needs.
