Say I have some simple class and once it's instantiated as an object I want to be able to serialize its contents to a file, and retrieve it by loading that file at some later time... I'm not sure where to start here, what do I need to do to serialize this object to a file?
public class SimpleClass {
public string name;
public int id;
public void save() {
/* wtf do I do here? */
}
public static SimpleClass load(String file) {
/* what about here? */
}
}
This is probably the easiest question in the world, because this is a really simple task in .NET, but in Android I'm pretty new so I'm completely lost.
Saving (w/o exception handling code):
FileOutputStream fos = context.openFileOutput(fileName, Context.MODE_PRIVATE);
ObjectOutputStream os = new ObjectOutputStream(fos);
os.writeObject(this);
os.close();
fos.close();
Loading (w/o exception handling code):
FileInputStream fis = context.openFileInput(fileName);
ObjectInputStream is = new ObjectInputStream(fis);
SimpleClass simpleClass = (SimpleClass) is.readObject();
is.close();
fis.close();
