and:

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent" >     <fragment       android:id="@+id/map"       android:name="com.google.android.gms.maps.supportmapfragment"       android:layout_width="match_parent"       android:layout_height="match_parent"/>  </relativelayout> 

as per understanding issue happening because of 3 reason

reasons

1) first lack of internet connectivity

2) second google api key missmatching

3) third if key ok provided package name during key generation not exact same project package name

solutions

for first need check internet conncetion working or not need go further

for second , third need create key proper steps if using eclipse then

eclipse-->windows-->preferences-->android-->build sha key

use sha key generate android key

after pasting sha key append project package name following symbol ";"

for example

yor_sha_key;your_project_main_package_name generate key google map key android use 1 hope resolve problem make sure using same pakcage name project package name

hope solve problem happy coding :)
