【问题描述】：
我正在开发带有 cordova 集成的流星应用程序。在这个应用程序中，我使用在 android 设备上运行速度非常慢的 html5 画布。我知道 FastCanvas phonegap 插件应该可以解决这个问题。但我在使用它时遇到了一些问题：
我包含这样的 FastCanvas 插件：Cordova.depends({
'com.adobe.plugins.FastCanvas': 'https://github.com/phonegap/phonegap-plugin-fast-canvas/tarball/2a91875b96485d35db189b80d105e5c572cfa0f4'
});
当我尝试在 android 上运行项目时，我得到了……（对不起，硬度 =)）：
