以下是我的堆栈跟踪：

我遇到了同样的问题，但只在v21上出现。（v16-v23测试正常）。奇怪的bug。 - John Shelley

我并不十分清楚其中原因，但我了解以下情况：SVG标准允许省略前导零以进行优化。这是根本原因，因为似乎可以随意将它们连接起来，例如0.1 0.2 0.3可以写成.1.2.3, Android的解析器无法处理这种情况。我所知道的所有SVG显示工具都没有问题。因此，您只需要在路径中添加一些空格。我编写了这个正则表达式，您可能需要多次运行直到没有匹配项。

在Android Studio中进行替换（选中“Regex”复选框）：

(\.\d+)(\.\d)

$1 $2

那将解决你的问题。

谢谢，@rekire，这真的很有帮助！除了不是所有的正则表达式匹配都需要被替换，我的可绘制对象因此无效，必须手动添加空格，只在崩溃消息指示的地方添加。 - gregko
有趣的一点是，正则表达式基本上是在寻找像“.1.1”这样的数字，其他组合应该被排除。你能提供一个假匹配的例子吗？我真的很想知道你得到了哪些错误的结果。 - rekire
