android . 内存泄露 LeakCanary 使用

1.build.gradle 添加

        debugImplementation 'com.squareup.leakcanary:leakcanary-android:1.6.1'
        releaseImplementation 'com.squareup.leakcanary:leakcanary-android-no-op:1.6.1'
        // Optional, if you use support library fragments:
        debugImplementation 'com.squareup.leakcanary:leakcanary-support-fragment:1.6.1'

2.自定义application

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...
    }
}
