Android泄漏金丝雀日志

标签： android memory-leaks leakcanary

我正在使用Leaky Canary来检测我的应用中的内存泄漏。虽然在此之前我能够摆脱2-3个问题，但我无法弄清楚这个日志泄漏的位置

11-14 18:05:05.335 32099-3554/? E/LeakCanary: Leak result dropped because we already store 7 leak traces.

在这种情况下，我无法分辨内存泄漏的位置。有人可以指出如何识别它吗？

11-14 18:05:05.330 32099-3554/? D/LeakCanary: * com.prism.prism.RatePicActivity_ has leaked:
11-14 18:05:05.330 32099-3554/? D/LeakCanary: * GC ROOT android.database.ContentObserver$Transport.mContentObserver

11-14 18:05:05.330 32099-3554/? D/LeakCanary: * leaks com.prism.prism.RatePicActivity_ instance

查看上面日志中的第三行，系统中某处有设置观察者的引用，其中包含对活动的引用。

所以很可能你没有取消注册你的内容观察者 SettingsObserver。请执行以下操作：

getContentResolver().unregisterContentObserver(settingsObserverReference);

以下是ContentResolver#unregisterContentObserver

的文档
