<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.maptest.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name="com.google.android.gms" />
    <uses-library android:name="com.google.android.maps" android:required="true" />

</application>

In addition, I assume, you followed other steps on Google Maps API setup documentation? — harism, Apr 22 '13 at 18:02

I think you have not added a reference to the Google Play Services library to your project. See this guide Google Maps Android v2 for more further helps.

You are most likely missing some permission(s) in your Manifest, probably MAPS_RECEIVE or READ_GSERVICES. Check this related question.

Edit: Insert your API key just before the closing tag </application>:

<meta-data
    android:name="com.google.android.maps.v2.API_KEY"
    android:value="your_api_key"/>

Add the ACCESS_NETWORK_STATE permission:

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

Delete these lines:

<activity android:name="com.google.android.gms" />
<uses-library android:name="com.google.android.maps" android:required="true" />

I have added all permissinon regarding this – user2289052 Apr 23 '13 at 04:08
But i am using MapView control in activity_main.xml file and also provide API key in MapView control , how can i insert API key in Manifest file . – user2289052 Apr 25 '13 at 04:08
@user2289052 You didn't _clearly_ state from the beginning which API _version_ you were trying to use. Setting your API key in your `com.google.android.maps.MapView` layout element was needed for - now deprecated - Maps Android **v1** API. For Maps Android API **v2**, which is using `com.google.android.gms.maps.MapView`, you only need to add your API (v2) key in your Manifest. Please follow the official [tutorial](https://developers.google.com/maps/documentation/android/) for API v2. Also, if this answer solves your problem, please accept it. – Nevermore Apr 25 '13 at 10:54

Please check whether you used Google android map in console and not Google Map. This might also be a problem. In addition to that another problem may be, you might have used map fragments. Use support Fragment in xml

android:name="com.google.android.gms.maps.SupportMapFragment"

GoogleMap gm;

gm = ((SupportMapFragment)(getSupportFragmentManager().findFragmentById(R.id.map))).getMap();

using above code error is coming - The method getSupportFragmentManager() is undefined for the type MainActivity – user2289052 Apr 25 '13 at 07:49
@user2289052 That error means your `MainActivity` extends `Activity` rather than `FragmentActivity` from [Android Support Library](http://developer.android.com/tools/extras/support-library.html). – Nevermore Apr 25 '13 at 15:07
