Did you put your apikey into mapview arguments correctly??

yesterday, I generated apikey (by debug mode md5 key) and that works well.

I mean


1. get your md5 code through keytool or something

2. generate your apikey in google map api page

3. use your apikey when you make mapview

Hi,
Sorry for the thread hijack but how do I actually go about using the generated api key with a debug application using Eclipse? As I'm currently only investigating android maps and how to use them then that's all I need at the moment.
I tried manually signing the apk file with the keytool generated keystore after I had put the api key in my xml file (application worked fine the other day before the enforcing of api keys). It didn't work after installing it on the emulator using adb.
Is there any n00b's guide to setting everything up? I seem to have managed to setup the keystore & got the api key from google but I'm thinking I must of missed something.

Cheers :D

Sorted, down to my own inexperience with tha java signing stuff etc. Thanks to this and this I realised that I can just use the default key in debug.keystore to generate the API key. So basically all I had to do was find out the MD5 as per Plusminus' instructions and generate the api key from that and all works from Eclipse now :D
