Android Lollipop 5.1 : Fatal signal 11 (SIGSEGV), 代码 2，错误地址 0x9e985ff8 in tid 4093 (RenderThread)/当使用大量 9-patch 图形时

Question

我在应用 View 中使用了大量的 NinePatchDrawables。底层位图被缓存，因此不存在内存问题。

在准备/绘制屏幕时，应用程序崩溃并显示以下日志条目:

04-03 19:37:42.651: A/libc(4064): Fatal signal 11 (SIGSEGV), code 2, fault addr 0x9e985ff8 in tid 4093 (RenderThread)

此问题刚刚在最新的 Android 5.1 版本(LMY47D、LMY47E、LMY47I)中出现。具有相同图形的相同 View 在 5.0.2 (LRX22C) 之前的早期 Android 版本上运行良好。我在 Nexus 6 上遇到了这个问题，到目前为止我还没有机会在任何其他设备上测试它。

只有在使用大量 NinePatchDrawable 时才会发生崩溃，尤其是将它们层叠在一起时。当我加载与普通 png 完全相同的图形(仅用于测试)时，它可以正常工作。其他具有较少 NinePatchDrawables 的 View 也可以正常工作。

同样的问题存在于早期的 Android 版本(5.0.2 或更早版本)上，但它只是发生在每个屏幕至少三到四倍的 NinePatchDrawables 上。

到目前为止(甚至在 Android M 中)还没有针对图形驱动程序错误 (Adreno 420) 的错误修复，但我找到了解决该错误的方法。这绝对不是一个长期的解决方案，但目前它只是阻止应用程序崩溃的最佳选择。

我将图形层的数量减少到最少(扁平化了许多分层图形)

我禁用了特定图形层的 GPU 渲染。它会稍微减慢绘图速度，但影响不大。

view.setLayerType(View.LAYER_TYPE_SOFTWARE, null);

在“软件”层中，如果需要，您仍然可以将特定 View 设置为“硬件”渲染。

view.setLayerType(View.LAYER_TYPE_HARDWARE, null);
