静态变量泄露android,Android内存泄漏,无静态变量

我是一名刚开始的Android开发人员,并且作为一个练习项目,我正在尝试进行活动并拍摄照片,将其保存到外部存储中,并在ImageView中显示.几乎所有东西似乎都在工作,但是,我似乎有内存泄漏.

当屏幕方向改变时,我相信该活动被破坏,然后重新创建.为了继续显示图像,我将图像的路径以字符串形式存储在onSaveInstanceState中的包中,并在onResotreInstanceState中重置图像.拍摄5mp的图片时,我可以旋转屏幕一次,然后在第二次旋转时,应用程序崩溃,LogCat报告内存不足错误.使用较低分辨率的图像时,旋转次数会增加,但应用最终仍会崩溃,并且会出现相同的错误.

我一直在阅读有关android内存泄漏的内容,并且似乎所有内容都说不要使用静态Drawables,它可以引用视图,并防止vm释放内存.据我所知,我没有做任何这样的事情来保持引用.如果有人可以帮助我找到我的错误,我将不胜感激.这是代码&＃xff1a;
