Bit of a weird question.

I’m passing data from one activity to another – specifically two GeoPoints. But, as I discovered, you can’t pass an ArrayList of type GeoPoint. I thought of converting them to strings and passing them through in an ArrayList of type string (so, geopoint1.tostring()), which went fine, but I have no idea how to then convert them back to a GeoPoint in the next activity.

What I’m doing might be totally mental and stupid, but I just can’t seem to think of any other way.

I’ve posted this quick question to try and get some quick responses, but if you need any more info just ask me, I’ll put it straight up.

BTW, I’m passing the data using intent.putExtra, etc.

Thanks guys!

    The getLatitudeE6()/getLongitudeE6() of GeoPoint returns an int.

    So you can use your coordinate in an array of int and send it with
    putExtra(String name, int[] value) from the intent

    int[] myGeoPoints = { 30, 50 };
putExtra("myCoordinates", myGeoPoints)

    and retrieve the array from the target activity with getIntent().getExtras().getIntArray

    getIntent().getExtras().getIntArray("myCoordinates")

    Or you can put the latitude/longitude with different key in the Intent’s Extra with
    putExtra(String name, int value)
