我目前正在为蜂窝创建一个应用程序，但我遇到了一些重大问题，我怀疑是openGL渲染器使用的内存。
情况是我有一个包含多个容器视图的滚动视图（可能有点多，如20）;这些容器视图每个都包含6个自定义视图，这些视图的layertype设置为由this.setLayerType(View.LAYER_TYPE_HARDWARE, null);加速的硬件（如果我没有设置它，所有内容都会被渲染，图像丢失或在错误的地方绘制等等）。我还有一个显示视频的视频。
现在，当我的应用程序被销毁并再次创建时（特别是在旋转时），应用程序就死了一个严重可怕的死亡，没有任何可调试的错误，除了日志显示很多GC和其他有关图形缓冲区的东西都没有记忆和各种死亡的东西：

答案 0 :(得分：2)
硬件层在内存方面非常昂贵。您应该只在视图上临时启用它们（例如，在动画的持续时间内。）要进入您描述应用程序的状态，必须在Xoom平板电脑上使用超过256 + 32 MB的视频内存。此外，如果您使用的是WebView，请小心，因为它本身会占用相当多的内存。
