为什么 Leak Canary 会将 Google Firebase API 检测为泄漏？

Question

为什么 Leak Canary 会将 Google Firebase API 检测为泄漏？ 当我在使用 firebase 时启动应用程序时，它会不断检测内存泄漏。有没有办法阻止这种情况？谢谢。

以下是忽略该站点小泄漏的建议解决方法：
First, disable the automatic install:

<resources>
  <bool name="leak_canary_watcher_auto_install">false</bool>
</resources>
Then install LeakCanary manually in your debug application, ignoring FirebaseAuthFallbackService:

class DebugExampleApplication : ExampleApplication() {

  override fun onCreate() {
    super.onCreate()

    val delegate = ReachabilityWatcher { watchedObject, description ->
      if (watchedObject::class.java.name != "com.google.firebase.auth.api.fallback.service.FirebaseAuthFallbackService
​  instance") {
        AppWatcher.objectWatcher.expectWeaklyReachable(watchedObject, description)
      }
    }

    val watchersToInstall = AppWatcher.appDefaultWatchers(application, delegate)

    AppWatcher.manualInstall(
      application = application,
      watchersToInstall = watchersToInstall
    )
  }
}
