I have created application using MapView element and custom itemized overlay. Then, accidentally, I have lost my API key v1. Unfortunately, it is not possible to obtain a new v1 key anymore and I don’t want to re-write application using MapFragment at all. MapFragment does not support most of MapView’s API, that is the problem.

I have tried inserting generated v2 key into the MapView element but it does not work. I am not sure if it is a problem of key versions or I have done something wrong.

    Then please stop all software development until you learn how to maintain proper backups of your development machine.

    Yes, it is. Quoting the documentation:

    Version 1 of the Google Maps Android API as been officially deprecated as of December 3rd, 2012. This means that from March 3rd, 2013 you will no longer be able to request an API key for this version.

    At the time of this writing, it is before March 3rd, 2013. Hence, you can visit the Maps API key signup page and request a key.

    MapFragment does not support most of MapView’s API, that is the problem

    I have not yet run into anything that V2 cannot do that V1 could. Yes, you will have to port your code over to use the new classes and methods. There is a decent chance that you will wind up with less code overall, though.

    I have tried inserting generated v2 key into the MapView element but it does not work.

    If you are referring to the original MapView from the Maps SDK add-on, the two services use different key systems AFAIK.
