Question

I'm trying to launch an intent from an activity class:

Intent i = new Intent(this, (Obscured)MapActivity.class);
    i.putExtra("stop", stop);
    this.startActivity(i);

And here is my intent receiver in (Obscured)MapActivity:

Intent i = this.getIntent();
if (i != null && i.getSerializableExtra("stop") != null) {
        this.displayLocations();
        BusStop tempStop = new BusStop();
        tempStop = (BusStop) i.getSerializableExtra("stop");
        this.goToStop(tempStop);
    }

But for some reason it isn't launching. I have another case right above that:

if (i != null && i.getSerializableExtra("loc") != null) {
        this.displayLocations();
        this.goToLocation((Location) i.getSerializableExtra("loc"));
    }

That works just fine, and the intent launcher code is almost completely identical. Any ideas?

EDIT: I'm also using SherlockListActivity, not sure if that changes anything.

<activity
        android:name=".(Obscured)MapActivity"
        android:configChanges="keyboardHidden|orientation|screenSize|uiMode|screenLayout"

I'm happy to provide more info, this has been bugging me for a few hours now.

ANSWER: Found the issue. For some reason when I add the extras (stop) which is serializable, it breaks. Commenting out the putExtra() and it works. The problem was trying to serialize a GeoPoint.

Answer 1

Found the issue. For some reason when I add the extras (stop) which is serializable, it breaks. Commenting out the setExtra() and it works. Not sure why it won't pass it though, the class extends serializable but everything I try just makes it break again.

Answer 2

Add this in manifest.xml

<activity android:name=".MapActivity"
    android:configChanges="orientation|keyboardHidden" />

I'm not sure if that helps, but the JavaDocs of putExtra() state that you must have a package prefix in the name of the extra:

The name must include a package prefix, for example the app com.android.contacts would use names like "com.android.contacts.ShowAll"
