A memory leak detection library for Android and Java.
โA small leak will sink a great ship.โ - Benjamin Franklin
In your build.gradle
:
dependencies {
debugCompile 'com.squareup.leakcanary:leakcanary-android:1.5.4'
releaseCompile '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.
To disable LeakCanary in unit tests, add the following to your build.gradle
:
// Ensure the no-op dependency is always used in JVM tests.
configurations.all { config ->
if (config.name.contains('UnitTest')) {
config.resolutionStrategy.eachDependency { details ->
if (details.requested.group == 'com.squareup.leakcanary' && details.requested.name == 'leakcanary-android') {
details.useTarget(group: details.requested.group, name: 'leakcanary-android-no-op', version: details.requested.version)
}
}
}
}
If you want to also disable leak detection in instrumentation tests, add || config.name.contains('AndroidTest')
to the
if
check above.
