我无法理解为什么这个非常简单的活动会产生内存泄漏.

它遵循此处给出的指导原则:https://developer.android.com/training/location/receive-location-updates.html以及此处给出的示例代码:https://github.com/googlesamples/android-play-location /树/主/ LocationUpdates

我还注意到,如果我不重写LocationCallback类的onLocationResult方法,则会解决内存泄漏问题.但就这种方式而言,LocationCallback完全没用.

谢谢您的帮助!
