我创建了一个包含大约 600 个小 ogg 文件的应用程序。总计约15MB。每个文件都会有平均值。 6秒的声音。这不是游戏应用程序，而是 child 学习应用程序。
我尝试在媒体播放器上加载声音。一次运行良好，连续播放时我最终没有声音。它是空白的。
所以我尝试了声音池选项。声音仅在加载到 soundpool 加载器后才播放。因此我尝试在应用程序的启动时加载声音。因此，加载声音大约需要 30 秒，之后主屏幕就会显示(我在后台使用异步加载声音，进度条显示在前面)。
此设置适用于大约 450 个 ogg 文件，当我添加超过 450 个声音时，我在加载几个声音时遇到堆错误，并且应用程序强制关闭并出现以下错误:

如何解决这个问题？堆上的大部分问题与数据库游标有关，而不是与 soundpool 有关。
如果这个问题无法解决，当我要加载 600 个声音时，使用 soundpool 的解决方法是什么？
谢谢!
最佳答案
有了这么多文件，您将需要延迟加载它们并转储一段时间未使用的文件。
有一个 LruCache在 Android 中，这将为您提供帮助。
