我正在 Sencha-touch 和 phonegap 中制作应用程序，需要您的帮助。我已经使用 eclipse 在模拟器（android 2.1、4.1）上成功运行了我的应用程序。我在三星手机（android 2.3.3）上成功运行了我的应用程序，但是当我在三星 Galaxy Tab 10.1（即 android-4.1.4）上运行它时，它只显示一个白屏。

此外，在 android 模拟器 4.0.3 上，我得到一个带有以下 logcat 文件的白屏：

你能帮我解决什么问题吗？提前致谢。

上面的答案有效，但如果您使用的是 Ext.Ajax，您还需要在配置中添加几个参数以找到这些文件。

noCache: false, 
enablePagingParams: false,

Sencha 论坛上的好帖子描述了这个问题和解决方法。

在任何 javascript 代码之前使用它：

Ext.Loader.setConfig({ disableCaching: false });
Ext.Ajax.setDisableCaching(false);

要使其在不同版本的 android 中工作，请在任何其他 javascript 之前在 HTML 文件的标头中添加代码。

<script>        
Ext.Loader.setConfig({
    enabled: true,
    disableCaching: false
    });

    Ext.Ajax.setDisableCaching(false);
</Script>
