我们的代码在 Canvas 上执行非常简单的操作（完全在 UI 线程中）：drawText、翻译、保存、恢复。

有时，我们会得到这个（在运行 4.3 的 Nexus 4 上）：

W/Adreno200-ES20(22118): <gl_draw_error_checks:550>: GL_INVALID_OPERATION
D/OpenGLRenderer(22118): GL error from OpenGLRenderer: 0x502
E/OpenGLRenderer(22118):   GL_INVALID_OPERATION

并且相应的文本不会绘制到画布上。

一个问题是它是随机发生的。该代码可能会在 10-20 次调用中正常工作，然后会出现此错误，然后在再次出现错误之前的另外 10-20 次调用中恢复正常工作。

如果您关闭硬件加速，则不会发生此错误。

在自定义视图的构造函数中：

setLayerType(View.LAYER_TYPE_SOFTWARE, null);

注意：我不会接受这个答案（还），因为它更多的是一种解决方法，而不是一个正确的解决方案。希望有更确定的东西...
