I had done all configuration.

Here is my manifest file:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.example"
      android:versionCode="1"
      android:versionName="1.0">
         <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
     <uses-permission android:name="android.permission.INTERNET" /> 

     <uses-sdk android:minSdkVersion="3" />
     <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
    <application android:icon="@drawable/icon" android:label="@string/app_name">
    <uses-library android:name="com.google.android.maps" />
        <activity android:name="com.example.HelloMap"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

and my layout file main.xml is
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:id="@+id/mainlayout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <com.google.android.maps.MapView
        android:id="@+id/mapview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:enabled="true"
        android:clickable="true"
        android:apiKey="*************"
    />
</RelativeLayout>

And my Hellomap.java

public class HelloMap extends Activity {
    LinearLayout linearLayout;
    MapView mapView;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mapview);
        mapView = (MapView) findViewById(R.id.mapview);
        mapView.setBuiltInZoomControls(true);

    }



    protected boolean isRouteDisplayed() {
        return false;
    }   
}

Something I am missing I guess, or maybe the issue is with 2.1 Google API?

If you are new in using google maps and you have set the xml and activity and you got this type of error, then it means that you have't extend your class from MapsActivity, so extend your class from mapsactivity, it will start working !

//wrong usage of activity

public class A extends Actvitiy
{   
 }
 //correct usage

public class A extedns MapsActivity {
 //your all program...
 }

Here i change Activity to MapActivity.

So Instead of

public class HelloMap extends Activity {

change it to

public class HelloMap extends MapActivity {

i got my answere myself

just see the exception log

last lines

MapViews can only be created inside instances of MapActivity. 06-14 22:13:34.031: ERROR/AndroidRuntime(331): at com.google.android.maps.MapView.(MapView.java:281) 06-14 22:13:34.031:

that means you need to extend your activity with MapActivity not Activity i guess most of you know but i got to know now :)

I had this problem and solved it by the following 2 steps:

1) Put the following line in the application (important) element of AndroidManifest.xml file.

<uses-library android:name="com.google.android.maps" />

2) extend MapActivity instead of Activity.

enjoy!
