在LifecycleObserver类中,保存Lifecycle对象引用的做法有多好?可能出现什么并发症?
class MyLocationListener implements LifecycleObserver {
private Lifecycle mLifecycle;
public MyLocationListener(Context context, Lifecycle lifecycle, Callback callback) {
mLifecycle = lifecycle
...
}
}

你不应该保留一个引用,它是内存泄漏的开放,Observer需要注意不要包含引用,如果你想对生命周期更改执行操作,请执行以下操作:
@OnLifecycleEvent(Lifecycle.Event.ON_DESTROY //you can change to whatever lifecycle event you need)
public void activityDestroied() {
//actions here
}
