please help!!
First correct this you need to move both <meta-data> tag under <application> tag in your manifest.xml like.
<application>
<activity....>
......
.......
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyA58hdExVacurnuB235ojNOJVsF6dH8MMg"/>
</application>
also here your minsdk="8" so you need to change this
public class MainActivity extends Activity
to
public class MainActivity extends FragmentActivity
also your logcat clearly said
05-31 07:42:01.640: E/AndroidRuntime(4133): Caused by: android.app.Fragment$InstantiationException: Trying to instantiate a class com.google.android.gms.maps.SupportMapFragment that is not a Fragment
That means you need to used
<fragment
class="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
