LeakCanary Setup

Ensure that you already have an explicit dependency in your application's build.gradle including the plugin dependency, e.g.

dependencies {
debugImplementation 'com.facebook.flipper:flipper-leakcanary-plugin:0.44.1'
debugImplementation 'com.squareup.leakcanary:leakcanary-android:1.6.1'
releaseImplementation 'com.squareup.leakcanary:leakcanary-android-no-op:1.6.1'
}

First, add the plugin to your Flipper client instance:

import com.facebook.flipper.plugins.leakcanary.LeakCanaryFlipperPlugin;
client.addPlugin(new LeakCanaryFlipperPlugin());

Next, build a custom RefWatcher using RecordLeakService: (see LeakCanary docs for more information on RefWatcher)

import com.facebook.flipper.plugins.leakcanary.RecordLeakService;
RefWatcher refWatcher = LeakCanary.refWatcher(this)
.listenerServiceClass(RecordLeakService.class)
.buildAndInstall();

Then, add the RecordLeakService in your debug variant AndroidManifest.xml.

<service android:name="com.facebook.flipper.plugins.leakcanary.RecordLeakService" />
