android - 错误 : RuntimeException at DisplayListCanvas. throwIfCannotDraw

Question

我的应用程序在 nougat 模拟器和许多设备上运行良好，但我在 google play crash reporter 中发现了这个异常，我不知道为什么会发生，该异常仅在 nougat 设备++ 上引起。

异常:

这个错误可能是什么？

注意:我使用的所有可绘制对象都小于 1MB。

Answer 1

我在使用 Samsung Galaxy S6 S7 S8 时遇到了完全相同的问题。在我的案例中，启动画面具有高分辨率，并且被错误地放置在可绘制文件夹中。我从 this 找到了解决方案回答。

1. 右键单击 drawable -> New -> Directory。
2. 输入新目录名称:xxhdpi。如果您转到 res
，它将创建一个名为 drawable-xxhdpi 的新文件夹
3. 将启动图像从 drawable 移至 drawable-xxhdpi。
