LatLng latLng = new LatLng(13.05241, 80.25082);
map.addMarker(new MarkerOptions().position(latLng).title("Raj Amal"));
}}
Plz if anyone can help

Update
First of all check that you have googleplayservice library added in your project, Then
Use FragmentActivity. Activity is not from v4 nor from v7 support libraries. This should work:
public class MainActivity extends FragmentActivity {
GoogleMap googleMap;
in onCreate
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext());
if(status!=ConnectionResult.SUCCESS){
int requestCode = 10;
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode);
dialog.show();
}else {
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
googleMap = fm.getMap();
}

Android application not showing my location in map, error: could not find 'com.google.android.gms.location.internal.parceablegeofence'

My android application is not showing my location on the map, but everything else is working fine and I have tried all the other solutions from other posts and google.
The locate button is showing but nothing happens when I click it and I don't know how to get the exception.
This is my code:
public class MainActivity extends FragmentActivity {
private GoogleMap myMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
initilizeMap();
myMap.setMyLocationEnabled(true);
myMap.getUiSettings().setMyLocationButtonEnabled(true);
} catch (Exception e) {
e.printStackTrace();
}
}
private void initilizeMap() {
if (myMap == null) {
myMap = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
if (myMap == null) {
Toast.makeText(getApplicationContext(),"Map not created", Toast.LENGTH_SHORT).show();
}
}
}
#Override
protected void onResume() {
super.onResume();
initilizeMap();
}
This is my androidmanifest:
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:text="Seleccione el punto clave" />
</RelativeLayout>
This is what logcat shows me:
Could not find 'gpq', referenced from method gpr.a
Could not find 'ovw', referenced from method oyf.a
Could not fin class 'com.google.android.gms.location.internal.parceablegeofence', referenced from method gls.a

I have solved it! just needed to implement a LocationListener to the MainActivity and its methods. Tell me if you need some code as answer.

How to Display Map in Android?

I worked on Google Map and use Fragment not Fragmentactivity but not working . my code given below.

android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
>
<com.google.android.gms.maps.MapView
android:id="#+id/mapview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>**
Map.java
public class Maps extends Fragment {
MapView m;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// inflat and return the layout
View v = inflater.inflate(R.layout.maps, container, false);
m = (MapView) v.findViewById(R.id.mapview);
m.onCreate(savedInstanceState);
return v;
}
#Override
public void onResume() {
super.onResume();
m.onResume();
}
#Override
public void onPause() {
super.onPause();
m.onPause();
}
#Override
public void onDestroy() {
super.onDestroy();
m.onDestroy();

this code but not success.
Gettin error like this..
java.lang.RuntimeException: API key not found. Check that <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="your API key"/> is in the <application> element of AndroidManifest.xml

you have to add one more meta-data in your Manifest.xml
meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="your key"

You have used mapv1 which is deprecated , use mapv2
