EGL错误:Nexus 10更新到Android 4.4后，我的应用程序中出现EGL_BAD_ALLOC

Question

Nexus 10更新到Android 4.4后，我的应用程序中出现EGL错误：EGL_BAD_ALLOC。由于以下错误，它会导致硬件加速关闭，然后完全阻止应用程序。

为了引起错误，我玩了包含谷歌地图Android API v2的片段，然后切换到HorizontalVariableListView(https://github.com/sephiroth74/HorizontalVariableListView)。有时滚动它会导致此错误。

有什么建议吗？当我的应用程序是android:targetSdkVersion="18"和android:targetSdkVersion="19"时，都会发生此错误

Answer 1

这个错误似乎是由映射视图中打开的文件过多引起的。这个错误后来导致硬件加速错误。现在我从LruCache加载缓存的图像，而不是只加载文件，错误消失了。
