Objects are still in memory after activity is destroyed

对象在内存中仍然存在，即使活动已被销毁，这可能会导致内存泄漏和应用程序性能问题。为了解决这个问题，可以采取以下措施：

使用生命周期感知组件：在 Android 中，可以使用 Lifecycle 库来处理生命周期事件，例如在活动销毁时释放资源。
使用 WeakReference：使用 WeakReference 可以确保对象在内存中不会被长时间占用，从而避免内存泄漏。
取消所有订阅：在活动中订阅数据时，务必在活动销毁时取消订阅，以避免内存泄漏。
使用 LeakCanary 工具：LeakCanary 是一个用于检测内存泄漏的工具，可以帮助开发人员快速定位和修复内存泄漏问题。
避免使用静态变量：静态变量会一直存在于内存中，可能导致内存泄漏。尽量避免使用静态变量来存储活动中的数据。
使用内存分析工具：使用内存分析工具，如 Android Studio 的 Memory Profiler，可以帮助开发人员查看应用程序的内存使用情况，从而找到潜在的内存泄漏问题。

Note for Google IO Memory Management for Android

So the heap in this case, was 65% free after the collection completed....But after a few collections, it does go back down to its previous value....So I should say that there is still a way to allocate native memory for your NIO byte buffers....So in that case, you’ll still be using native memory. But either way, it’s just memory....So is this still there or is it gone now that there is no more native memory allocated?
