存储Parcelable对象以Android的文件 [英] Storing a Parcelable object to a File in Android

问题描述

我试图对象ResolveInfo的ArrayList保存到一个文件中，这样我就不必每次我的应用程序启动（约4-6秒）ResolveInfo对象Parcelable重建它，但不能序列化，所以我得到一个java.io错误，当我尝试写的对象。

I am trying to store an ArrayList of ResolveInfo objects to a file so that I don't have to rebuild it each time my application launches (about 4-6 seconds) ResolveInfo objects are Parcelable, but not Serializable so I get a java.io error when I try to write the objects.

我已存储他们在我savedInstanceState捆绑，但在关闭应用程序时没有帮助。我做得完全错误的？

I have stored them in my savedInstanceState bundle, but that doesn't help when closing the application. Am I doing something plain wrong?

推荐答案

savedInstance信息不会在多个会话保存。你真的要实施序列化保存 ResolveInfo 。

savedInstance info will not save across multiple sessions. You will really want to implement Serializable to save your ResolveInfo.
