Question

[这是应用启动的时间][1] [这是在打开 Activity 或进行一些操作后，内存保持在 460mb 以上][2]2

在应用程序中，我在数组中有一些视频，还有一些视频是从服务器加载的，我还使用 gif 图像和其他资源。我已经压缩了资源以查看我是否没有问题但是当运行应用程序在范围较小的移动设备上时，它会因内存不足而关闭。我使用 Samung s7 进行 4gb ram 的测试，即便如此，当更改 activity 时也会使其变慢。请帮助我

Answer 1

您不应在应用程序中保留一系列视频。相反，您可以保留视频文件的路径和 url 并且一次只加载一个需要播放的视频。也尝试使用图像缓存库，如 Picasso 或 Glide，它们也会解决大图像的内存问题。
