推荐答案
你指的是从JavaScript抛出的错误，我想（否则应用程序会崩溃）？
The error you are referring to is thrown from javascript, i guess (otherwise the app would crash)?
什么Android操作系统版本是你想做到这一点呢？如果是2.x的，你不会跑远，除非你的谷歌图表使用备用渲染器如的 canVg （我知道highcharts使用canvg成功为），因为的WebView不知道SVG。
What Android OS Version are you trying to do this on? If it's 2.x, you won't get far unless your Google Chart uses a fallback renderer such as CanVg (i know highcharts uses canvg with success for that), because the WebView doesn't know svg.
