Please find below code.

Manifest.xml --added all required permissions and API key

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

    </application>


</manifest>

map_view.xml --layout file

<?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.MapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</RelativeLayout>

Activity_Map.java

    package com.achra.fmap;

    import android.app.Activity;
    import android.os.Bundle;
    import android.widget.Toast;

    import com.google.android.gms.maps.GoogleMap;
    import com.google.android.gms.maps.MapFragment;

    public class Activity_map extends Activity {

    // Google Map
    private GoogleMap googleMap;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map_view);

        try {
            // Loading map
            initilizeMap();

        } catch (Exception e) {
            e.printStackTrace();
        }

    }

    /**
     * function to load map. If map is not created it will create it for you
     * */
    private void initilizeMap() {
        if (googleMap == null) {
            googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                    R.id.map)).getMap();

            // check if map is created successfully or not
            if (googleMap == null) {
                Toast.makeText(getApplicationContext(),
                        "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                        .show();
            }
        }
    }

    @Override
    protected void onResume() {
        super.onResume();
        initilizeMap();
    }

    }

We could see map grid on screen but map doesn't appear. Please guide further.

We are using Google Maps API v2.

try changing the `MapFragment` to `SupportMapFragment` – Rod_Algonquin May 09 '15 at 22:16 — Rod_Algonquin, May 09 '15 at 22:16

Looks like you're missing com.google.android.gms.version in your AndroidManifest.xml.

If you look at your logs you will probably see this:

You must have the following declaration within the <application> element:        <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

Try adding it just below your API key:

    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="removed key intentionally" />
    <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

On adding "com.google.android.gms.version" to Manifest.xml, we are getting below error on line "@integer/google_play_services_version" -> No resource found that matchesthe given name. We did import package google-play-services_lib in workspace. – Achra May 09 '15 at 23:17

@Achra This answer might help too. If all else fails, do Project->clean a couple of times. http://stackoverflow.com/questions/19879844/adding-google-play-services-version-to-your-apps-manifest/22648826#22648826 – Daniel Nugent May 09 '15 at 23:27
