问题
I am making an app in Sencha-touch and phonegap and need your help. I have succesfully ran my app on an emulator (android 2.1, 4.1), using eclipse. I ran my app successfully on a samsung phone(android 2.3.3), but when I run it on samsung galaxy tab 10.1(which is android- 4.1.4), it just shows a white screen.
Moreover on an android emulator 4.0.3, I get a white screen with following logcat file:

回答1:
use this before any javascript code :
Ext.Loader.setConfig({ disableCaching: false });
Ext.Ajax.setDisableCaching(false);
回答2:
The above answer works, but if you're using Ext.Ajax you also need to add a couple parms to the config to get those files to be found.
noCache: false,
enablePagingParams: false,
Great post on the Sencha forum describing this problem and the work-around.
回答3:
To make it work in different versions of android add the code in header of your HTML file before any other javascript.
<script>
Ext.Loader.setConfig({
enabled: true,
disableCaching: false
});
Ext.Ajax.setDisableCaching(false);
</Script>
