我正在使用Leaky Canary在我的應用程序中檢測內存泄漏。雖然我能夠在這之前幹掉2-3個問題，我想不出哪裏泄漏是從該日誌Android泄漏金絲雀日誌

我無法分辨其中的內存泄漏在這種情況下發生的。有人可以指出如何去識別它嗎？

看看上面的日誌中的一行三人，有系統某處，又包含參照活動設置觀察者的參考。

所以很可能你沒有取消註冊你的內容觀察者SettingsObserver。請不要像下面這樣：

getContentResolver().unregisterContentObserver(settingsObserverReference);

這裏是ContentResolver#unregisterContentObserver

看起來像在android內部的泄漏。我也面臨類似的TextSpans等漏洞。如果你找不到任何類似的問題，請打開一個跟蹤，有人可能會指出你的解決方案/解決方案。 –
