Android: Homescreen Shortcut with Serializable Extra

Question

I want to create a homescreen shortcut to an inner activity of my app. This answer helped to get me started.

Here's the basic code:

Intent shortcutIntent = new Intent(context.getApplicationContext(),
        StationMainActivity.class);
shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
shortcutIntent.setAction(Intent.ACTION_MAIN);

Intent addIntent = new Intent();
addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, stationData.getName());
addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,
        Intent.ShortcutIconResource.fromContext(context.getApplicationContext(),
                R.drawable.ic_launcher));

addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
addIntent.putExtra("duplicate", false);
context.getApplicationContext().sendBroadcast(addIntent);

Unfortunately, while it does work to provide an extra of type String the code appears to fail if I try to provide a serializable extra to the shortcutIntent.

    shortcutIntent.putExtra("StationId", (String) stationData.getId());

does work. But

    shortcutIntent.putExtra("StationData", stationData);

where stationData is a serializable Object does not. So right now I provide all fields of the object as string and recreate the object when the activity is called. This does work but it's cumbersome and dirty code.

Any idea why providing a serializable object does not work in this case? Thanks.

Update: Here's how I try to retrieve the Serializeable:

    stationData = (StationData) intent.getSerializableExtra("StationData");

StationData looks like this:

public class StationData implements Serializable {
    private String id; 
    private String name; 
    ...

    public StationData(String id, String name, ....) {
      this.id = id; 
      this.name = name; 
      ...
    }
 }

Is your stationData extending from serializable? also can you provide the code on how are you getting the extras ? — PedroAGSantos, Jul 26 '16 at 07:49
Yes it is. Serialization works well if it is not used for the shortcut intent. — Androidicus, Jul 26 '16 at 08:58
Can you provide the code when you retrieve the serialisable? — PedroAGSantos, Jul 26 '16 at 09:54

when you try to get data try to use:

Bundle extras = getIntent().getExtras();
extras.getSerializable("StationData");
