Android 安卓内存泄漏导致内存不足错误。使用查看寻呼机。
我从以下代码中得到内存泄漏。它是一个包含mainViewPager的活动。该viewPager返回4个不同的片段，每个片段都有自己的viewPager，其中包含从同一任务检索的图像。这是我的密码。当我运行它时，我可以在页面之间滚动一些延迟。但当我退出“返回”活动时，会出现内存不足错误。所以这一定是内存泄漏。我一直盯着我的代码看，我不知道为什么。请帮帮我。。。另外，我正在使用毕加索图书馆从服务器上获取图像 活动Android 安卓内存泄漏导致内存不足错误。使用查看寻呼机。,android,android-fragments,memory-leaks,android-viewpager,out-of-memory,Android,Android Fragments,Memory Leaks,Android Viewpager,Out Of Memory,我从以下代码中得到内存泄漏。它是一个包含mainViewPager的活动。该viewPager返回4个不同的片段，每个片段都有自己的viewPager，其中包含从同一任务检索的图像。这是我的密码。当我运行它时，我可以在页面之间滚动一些延迟。但当我退出“返回”活动时，会出现内存不足错误。所以这一定是内存泄漏。我一直盯着我的代码看，我不知道为什么。请帮帮我。。。另外，我正在使用毕加索图书馆从服务器上获取图像 活动 package info.nightowl.nightowl; import inf
