强制关闭后共享preferences重置 [英] SharedPreferences being reset after force close

问题描述

我已经能够成功地实现共享preferences到我的应用程序，但我已经遇到了与数据重置/如果我杀了通过任务管理器应用程序中删除的问题。

I have been able to successfully implement Shared Preferences into my application but I have ran into a problem with the data being reset/deleted if I kill the application through a task manager.

我使用的是静态方法保存，这样，我只需要方法一次，并且可以在我的应用程序无处不在调用它。

I am using a static method for saving, that way I only need the method once and can call it everywhere within my app.

protected static synchronized void save(Context cntx){
    SharedPreferences preferences2 = cntx.getSharedPreferences("BluRealms", 0);
    SharedPreferences.Editor editor = preferences2.edit();
    editor.putBoolean("level", Stats.level);
    editor.commit();
}

只要我杀了我的应用程序所有的数据被重新设置为我的共享preferences默认设置保存方法。

As soon as I kill my app all of my data gets set back to the default settings in my SharedPreferences save method.

我也做了一些搜索，发现了几个职位，说将机器人：执着=真到清单文件将解决这个问题，但该数据仍与该重置甚至

I also did some searching and found a few posts that say adding android:persistent="true" into the of the manifest file would fix the problem, yet the data is still reset even with this.

编辑：嗯，我想我找到了一点信息，我的问题。本期突出了与三星Galaxy S手机不保存共享preferences正常，这是我测试的设备有问题。 HTTP：//$c$c.google.com/p ？/安卓/问题/细节ID = 14359 - 尤其是注释6

Well I think I found a bit of information on my problem. This Issue highlights a problem with Samsung Galaxy S phones not saving SharedPreferences properly, which is the device I am testing on. http://code.google.com/p/android/issues/detail?id=14359 - especially comment 6

在此更多的信息将是巨大的！

Any more information on this would be great!

推荐答案

好吧我能够从我的保存方法删除受保护的静态来解决这个问题。

Ok I was able to solve this by removing the "protected static" from my save method.

，我只是摆在每个类的保存方法，将需要保存，然后只调用保存的方法在的onPause（）和的onDestroy（）方法。

Instead of calling a global save method, I simply placed the save method in each class that would need to save and then only call the save method in the onPause() and onDestroy() methods.

我发现，如果我叫保存（）一类似乎也抹去我的共享preferences当我关闭了应用程序内的次数太多。

I noticed that if I called save() too many times within a class that also seemed to erase my SharedPreferences when I closed the app.

提示：

不要使用静态方法来获取或设置共享preferences

Do not use static methods for getting or setting shared preferences
