RoboGuice 3.0已经记录了一个问题:https://github.com/roboguice/roboguice/issues/328

但没有回应,我们目前被阻止.

问题解决了

这次我更仔细地提到了MultiDex Document,并将我更新AndroidManifest.xml到了我错过的下面

<application
        ...
        android:name="android.support.multidex.MultiDexApplication">
        ...
    </application>
</manifest>

我刚刚使用bower with below命令在我的项目中添加了jQCloud2库

bower install jqcloud2 --save

jQCloud - http://mistic100.github.io/jQCloud/demo.html

在头部添加了它的css和javascript文件

下面是我正在使用的一小段代码

<div id="cloud">
</div>
<script>
$(function(){
  var words = [
  {text: "Lorem", weight: 13},
  {text: "Ipsum", weight: 10.5},
  {text: "Dolor", weight: 9.4},
  {text: "Sit", weight: 8},
  {text: "Amet", weight: 6.2},
  {text: "Consectetur", weight: 5},
  {text: "Adipiscing", weight: 5}
];

$('#cloud').jQCloud(words);
});
</script>

我正在使用的库

1. jQuery - 1.11.3
2. jQuery-UI - 1.11.3
3. Bootstrap - 3.3.5
4. jQCloud2 - 2.0.1

我没有看到任何代码通过jQCloud库生成,这是我一直在做的错误.非常感谢您的帮助
