以编程方式在Android上明确的PhoneGap /科尔多瓦应用程序的高速缓存来模拟一个新的安装？ [英] Programmatically clear PhoneGap/Cordova app's cache on Android to simulate a fresh install?

问题描述

这是关系到我的previous的<问题href="http://stackoverflow.com/questions/11142069/how-can-i-clear-my-apps-localstorage-on-my-android-emulator-each-time-i-install">How我可以清楚我的应用程序的localStorage的在我的Andr​​oid模拟器我安装它每一次？。

This is related to my previous question of 'How can I clear my app's localStorage on my Android emulator each time I install it?'.

这也建立在我如何清除Android应用程序缓存？和如何编程明确的应用程序数据？

无上述问题给出一个简单的答案是适用到Android的PhoneGap /科尔多瓦应用。 <一href="http://www.hrupin.com/2011/11/how-to-clear-user-data-in-your-android-application-programmatically"相对=nofollow>本博客文章通过伊戈尔Hrupin 涵盖的<强的背景情况>的本机的 Android的应用程序，所以这个问题扩展了覆盖科尔多瓦。

None of the above questions give a straightforward answer that is applicable to Android PhoneGap/Cordova applications. This blog post by Igor Hrupin covers the situation in the context of a native Android app, so this question extends that to cover Cordova.

我会后回答自己，但我是一个总的Java小白，所以请编辑来改善。

I will post an answer myself, but I am a total Java noob, so please edit to improve.

推荐答案

我是不是能够给力的Andr​​oid重新加载新的版本：

I wasn't able to force android to reload new versions of:

super.loadUrl("file:///android_asset/www/index.html");

调用之间，所以我先借这已经足够好了，除了我的应用程序编写所有的数据已被删除，以及您的code。

between calls, so I first borrowed your code which worked well enough except that all data that my application was writing was deleted as well.

一个快速和简单的解决方法就是改变上述文件的URL：

A quick and simple fix is to change the URL of the file above:

super.loadUrl("file:///android_asset/www/index.html?1");

和改变落后多少？每个负载。最后我说：

And change the number behind the ? with each load. Eventually I added:

import java.util.Random;

public class MainActivity extends DroidGap {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        Random generator = new Random();
        int r = generator.nextInt();
        super.onCreate(savedInstanceState);
        super.loadUrl("file:///android_asset/www/index.html?" + r);
    }
}

现在我每次重建应用程序，它实际上刷新的HTML文件的缓存版本。

Now each time I rebuild the app it actually refreshes the cached version of the html file.

我会非常想知道如何强制使用loadURL到刷新从应用程序本身，或迫使它重新加载。

I'd very much like to know how to force loadUrl into a refresh from within the app itself, or to force it on reload.
