Google Maps V2 Not Woking

Question

I m using google maps v2 and getting this error.

Could not find class 'maps.af.k', referenced from method maps.ag.an.a

I m following all the rules correctly. I have created SHA1 finger print and added it to ANdroid Key for apikey with projct name

1F:41:29:EC:E8:07:3C:A9:F8:6E:EB:D2:7B:42:41:62:3A:36:CA:F2;com.example.routes

Then in mainest file i m using

<fragment
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:id="@+id/map"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"/> 

i have also imported the googleplayservices and correctly added it to the project

My code is

public class MainActivity extends FragmentActivity {
GoogleMap googleMap;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    SupportMapFragment fragment = new SupportMapFragment();
    getSupportFragmentManager().beginTransaction()
            .add(android.R.id.content, fragment).commit();
    ;

     googleMap = ((SupportMapFragment)    

  getSupportFragmentManager().findFragmentById(
                R.id.map)).getMap();
  }
}

but still i m getting that error.

Try to extend Activity rather then FragmentActivity:

  public class MainActivity extends Activity implements LocationListener{
LocationManager locationManager;
    private GoogleMap googleMap;
double lat=17.385044;
double long=78.486671;
 @Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
    LocationManager service=(LocationManager)getSystemService(LOCATION_SERVICE);
    locationManager=(LocationManager)getSystemService(Context.LOCATION_SERVICE);
 Criteria criteria = new Criteria();
    provider = locationManager.getBestProvider(criteria, false);
   Location location = locationManager.getLastKnownLocation(provider);
  private void initilizeMap(){
if(googleMap==null){
 googleMap=((MapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();
    //check if map is created succesfully or not
    if(googleMap==null){
Toast.makeText(getApplicationContext(),"sorry unable to create map",1).show();
    }
 } 
MarkerOptions markerOptions=new MarkerOptions().position(new LatLng(lat,long));
markerOptions.icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_launcher));
CameraPosition cameraPosition=new CameraPosition.Builder().target(new LatLng(17.385044,     78.486671)).zoom(12).build();
 googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
 googleMap.setMyLocationEnabled(true);
 googleMap.setOnInfoWindowClickListener(null);
 }

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

When you are using SupportMapFragment no need of extending FragmentActivity just extend the Activity See the below example code:

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;

public class MainActivity extends Activity {

private GoogleMap map;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    map =  ((MapFragment)   getFragmentManager().findFragmentById(R.id.map)).getMap();

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

Note: You have to add google play services library project as a reference to your project, your package name must be com.example.routes you have to add the map fragment in your xml layout not in the manifest. Make following changes to your Manifest.xml Add following permissions.

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

Add the OpenGL

<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true"/>

Add the API key

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

Example manifest:

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

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="18" />

   <uses-permission android:name="android.permission.INTERNET"/>
   <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
   <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
   <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
   <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

<used-feature 
    android:glEsVersion="0x00020000"
    android:required="true"/>

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    <activity
        android:name="com.example.package.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>
    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="YOUR_API_KEY_HERE"/>
</application>

I had the same problem and my solution was to remove and add the googleplayservices again.
