像 Java 这样具有垃圾回收功能的语言的好处之一,就是程序员无需手动管理内存分配。这减少了段错误(segmentation fault)导致的闪退,也减少了内存泄漏导致的堆空间膨胀,让编写的代码更加安全。然而,Java 中依然有可能发生内存泄漏。所以你的安卓 APP 依然有可能浪费了大量的内存,甚至由于内存耗尽(OOM)导致闪退。 传统的内存泄漏是由忘记释放分配的内存导致的,而逻辑上的内存泄漏则是由于忘记在对象不再被使用的时候释放对其的引用导致的。如果一个对象仍然存在强引用,垃圾回收器就无法对其进行垃圾回收。在安卓平台,泄漏 Context 对象问题尤其严重。这是因为像 Activity 这样的 Context 对象会引用大量很占用内存的对象,例如 View 层级,以及其他的资源。如果 Context 对象发生了内存泄漏,那它引用的所有对象都被泄漏了。安卓设备大多内存有限,如果发生了大量这样的内存泄漏,那内存将很快耗尽。 如果一个对象的合理生命周期没有清晰的定义,那判断逻辑上的内存泄漏将是一个见仁见智的问题。幸运的是,activity 有清晰的生命周期定义,使得我们可以很明确地判断...
