Android :: MapView Always Displays Blank White Sceen

I'm creating a basic Mapview application which will display my current location on the google map. Initially i had many doubts while creating the application, but thanks to android developers archives that helped me to reach this point. I have followed almost all the threads on the android developers site but still unable to see my location on the google maps. It always shows a white screen on the emulator with google image at the bottom. Please help to make it work. From most of the threads I learn that we need to sign our application with the correct fingerprint. I did so but unsuccessful.

The following will explain the steps:

1. Using sdk version android-sdk-windows-1.0_r1
2. Created a new android application.
3. Signing the application:

a. C:Program FilesJavajdk1.6.0_13in>keytool.exe -list -alias androiddebugkey -keystore "D:Profilesfknq86Local SettingsApplication Data Androiddebug.keyst ore" -storepass android -keypass android

b. Certificate fingerprint (MD5): 75:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:33 where XX=some alpha numeric data

c. signing up for an Android Maps API key!

Using link http://code.google.com/android/maps-api-signup.html 4.

Code below: There are 2 applications

1. Find Me

2. ShowMyLoc.

FindMe has a button which directs it to ShowMyLoc (using Intent) to show the location on the google maps. For simplicity sake i'm pasting the code only for ShowMyLoc app.
