Option #1:

The Application class could be what you're looking for. There is a very good answer that explains how to use it and actually it is everything you need. You can find the answer here: Android: How to declare global variables?.

Option #2:

Use Intent.putExtra(...) method to send further data from your previous Activity to your next Activity.

Option #3:

This is a dirty quick fix (not recommended). Declare your data object as static and reach it by using YourActivity.mMyDataObject.

do it in "Android Way"

use ContentProvider

public void onItemClick(AdapterView<?> l, View v, int position, long id) {
    Intent itemIntent = new Intent(this, ItemActivity.class);
    listIntent.setData(Uri.withAppendedPath("content://my.app.content/edition", Long.toString(id)));
    startActivity(listIntent);
}

then in ItemActivity:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.item_activity);
    Intent intent = getIntent();
    if (intent != null) {
        Uri uri = intent.getData();
        if (uri != null) {
            Cursor cursor = managedQuery(uri, new String[] { "All", "Columns", "That" }, null, null, null);
