Genymotion just Doesnt launch GoogleMapsDemo Application-Eclipse.

I downloaded project of GoogleMapsDemo Application, it hasnt got errors on Eclipse. But in genymotion emulator it keeps saying unfortunately application cannot be launched.
Its MY Android manifest:

If you want to use Google services(like Google Maps), you need to first set up Google Play Services for Android, you may following the instruction form here. (Get your own API key, put in your AndroidManifest.xml, etc.)
I suggest you using a real device to test. If you want to use the Genymotion as a emulator, you need also get the google service first. For more details, please refer here.

Can´t run my app with google maps api v2

I tried everything, I researched and I can't get run my application. Each time I Run my application on my device get the message: "Sorry, Map has been has been interrupted". I done all the steps from this page https://developers.google.com/maps/documentation/android/start?hl=pl, and follow many tutorial and nothing. I hope you can save me.

Please Help me!!!!

try this :
class="com.google.android.gms.maps.SupportMapFragment"
on your activity :
SupportMapFragment mapfragment = (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.showmap);

I think your problem in
android:name="com.google.android.gms.maps.MapFragment"
try instead of this, in the way:
class="com.google.android.gms.maps.MapFragment"
P.S. sometimes problem with maps is in not available Google Play Service on device.
(GooglePlayServicesUtil.isGooglePlayServicesAvailable(this) == ConnectionResult.SUCCESS)
must be true.

Google Maps V2 Not Woking

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();
}

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

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" >

Use your main packet name for generate key.
For example:
im my project, google map v2 is in com.ftravelbook.googlemapv2
but when generate key, you must use your main packet name (com.ftravelbook)
here are some screenshots:

I was also having the same problem because i have generated key by making on google maps api v2 on.It is used for web not for mobile.
For android device you have to make a google maps android api v2 on and generate your key

Is your map API key for your debugbuilds or your release builds? The key is based on your keystore, which is different between your debug and release build. Your release key for google maps won't work if you're debugging your app, and vice versa.

location button not pointing me to my location in google map api v2

Try turning GPS satellites off in Location access settings. If it's enabled but GPS can't be reached, the my location button fails silently; by turning it off it apparently forces the feature to use the network provider.
