LeakCanary

A memory leak detection library for Android and Java.

“A small leak will sink a great ship.” - Benjamin Franklin

Getting started

In your build.gradle:

dependencies {
  debugImplementation 'com.squareup.leakcanary:leakcanary-android:1.5.4'
  releaseImplementation 'com.squareup.leakcanary:leakcanary-android-no-op:1.5.4'
}

In your Application class:

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 memory leak is detected in your debug build.
