如何从LeakCanary中排除类？
如何从LeakCanary中排除类？
提问于 2019-02-09 03:04:11
我正在做这个：
ExcludedRefs excludedRefs = AndroidExcludedRefs.createAppDefaults()
.clazz("androidx.lifecycle.ReportFragment")
.reason("Very annoying report fragment leak that isn't a leak apparently")
.alwaysExclude()
.build();
LeakCanary
.refWatcher(context)
.listenerServiceClass(DisplayLeakService.class)
.excludedRefs(excludedRefs)
.watchDelay(10, TimeUnit.SECONDS)
.buildAndInstall();但我还是拿到了ReportFragment was never GCed but no leak found。
我的一项活动也是如此，我不知道如何处理这些no leak found消息。
编辑:当前使用LeakCanary 1.6.3

我找到了这个；我想我可以试试
这和预期的一样工作。在执行堆转储和分析之前，我们不能知道是否排除了泄漏。一旦我们这样做了，默认行为是显示一个前缀为Excluded的通知。这让用户知道LeakCanary已经完成了。如果根本没有反馈，您将无法知道是否完成了泄漏金丝雀。这可以说是一种比根本没有反馈更好的用户体验。
您可以通过提供自己的com.squareup.leakcanary.AbstractAnalysisResultService子类而不是使用缺省的com.squareup.leakcanary.DisplayLeakService来自定义此行为
