LeakCanary example

In the example above, the signature of the leak would be computed as: val leakSignature = sha1Hash(com.example.leakcanary.LeakingSingleton.leakedView + java.util.ArrayList.elementData + java.lang.Object []. [x]) println(leakSignature) // dbfa277d7e5624792e8b60bc950cd164190a11aa 4 package com.example.leakcanary: import android.app.Application: import android.app.Dialog: import android.app.Service: import android.os.StrictMode: import android.view.View: import leakcanary.AppWatcher: import leakcanary.ReachabilityWatcher: import leakcanary.RootViewWatcher: open class ExampleApplication: Application() {val leakedViews = mutableListOf < View > ( LeakCanary will help you find and fix these memory leaks during development. When Square engineers first enabled LeakCanary in the Square Point Of Sale app, they were able to fix several leaks and reduced the OOM crash rate by 94% LeakCanary The easiest way is to use LeakCanary. Edit your application module's build.gradle to add the following dependencies. dependencies { // https://github.com/square/leakcanary/releases debugCompile 'com.squareup.leakcanary:leakcanary-android:1.5.2' releaseCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.5.2' } Setup LeakCanary at your Application class. public class MainApplication extends Application { @Override public void onCreate() { super.onCreate(); if. To avoid accidentally including the com.squareup.leakcanary:leakcanary-android dependency in a release build, LeakCanary crashes during initialization if the APK is not debuggable. You may have a good reason to create a non debuggable build that includes LeakCanary, for example for a QA build

As the name indicates, this Activity demonstrates a common cause for a leak. I did some research to find out how LeakCanary gets the reference path that is causing the leak. In LeakCanary, this path is called Leak Trace and according to its documentation it is the best strong reference path from garbage collection.
