Using putSerializable in Android
<p>Is putSerializable broken?</p>

<p>When I pass null with putSerializable the FillSummary.class starts as it should.
If I however pass the a TestSerial object than Android force closes.</p>

<p>What do I have to do to get a custom object transfered via a Bundle? </p>

<pre><code>public class TestSerial implements Serializable{
    private static final long serialVersionUID = 2310640779687082782L;
    public int i;
    public TestSerial(){
        i=1;
    }
}

private void renderSummary(){

    Intent intent = new Intent(FillForm.this, FillSummary.class);
    Bundle extras = new Bundle();

    extras.putSerializable("test serial", new TestSerial());
    intent.putExtras(extras);

    startActivityForResult(intent, Forms.DISPLAY_SUMMARY);
}
</code></pre>

<p>Error:</p>
