Did you compile properly the google play services in your build.gradle... you can follow the steps at the android developers site... http://developer.android.com/google/play-services/setup.html... and maybe you will have to use the gmaps api v3...

I tried following the tutorial from Google here. I believe I followed every instruction written but I still get nullpointexception when I try to get my long and lat coordinates.
It works fine if I press the target icon in the map that redirects me to my current location. But when I try it programmatically, it returns nullpointexception. I tried looking in stackoverflow for similar situations like mine but so far none of them works.
If you can provide me with a sample working source file or code that I can test myself it is much appreciated. Below are my source code in case I missed something. Thanks in advance.

Here is the xml file of my layout.
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.MapFragment"/>
I dont know what you have done in your xml file,but your xml file must look like this:
activity_main.xml
<?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>
Also Add the following,
< meta-data android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" >
< /meta-data>
in your manifest file immediately below the first meta-data tag(where you have placed your google api key).
Also I havent used the camera code that you have written to animate camera.My code:
CameraPosition cameraPosition = new CameraPosition.Builder().target(
new LatLng(your_lat, your_long)).zoom(12).build();
map.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
Finally got it to work. It seems that the problem is the network provider.
Instead of using Criteria and getBestProvider I followed this approach. What it does is loop to a list of network provider and returns the best existing provider in your mobile phone manually.

You are missing a meta tag in the manifest file
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
You don't need these
<permission
android:name="com.geo.app.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
Also it is better to check the availability of google play services before intializing GoogleMap object
Edit:
java.lang.NoClassDefFoundError: com.google.android.gms.R$styleable
You haven't referenced google play services library project in your android map project.
In your MainActivity.java class change the fragment import statement
import android.support.v4.app.Fragment
Im almost just a beginner in android. I was trying to make a very simple app with google maps, ie just displaying maps. I followed the following link:
file:///C:/Android/Android%20Google%20Maps%20V2%20Tutorial.htm
But when I test it on my device it says it has stopped working and closes.
Here is my Manifest.xml:
<?xml version="1.0" encoding="utf-8"?>

// check if map is created successfully or not

"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
}
#Override

and XML code is( some part of it):

I have googled a lot about it and got some direct questions on it but no answer ?? .
It seems many have the same problem.Can anyone help with this problem. I want to develop an app but not able to proceed as Google mpas api is main part of it.
Your are missing a meta tag in the application tag of manifest
<meta-data
android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version" />
You should use SupportMapFragment instead of MapFragment.
Change
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
to
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Change
googleMap = ((MapFragment) getFragmentManager().findFragmentById(
R.id.map)).getMap();
TO
googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(
R.id.map)).getMap();
Whatever you have done is ok with older version of GooglePlayServices, but its apparently visible from your logcat that you are using GooglePlayServices 13 or higher so you need to add the meta data tag in your manifest just the way Raghunandan have answered.
I'm developing an application which uses a map. I use my galaxy nexus to test the app but after I included the code related to the map it stopped working on my phone but it still works on the emulator. The problem is that the emulator doesnt show the map because it doesnt have Google Play Services.
When I try to launch the app I get no error but my phone does nothing, and if I try to run it manually from the app drawer the app is there but it says "isn't installed".
Here is the java code MainActivity.java
package myPackage.android;
import com.actionbarsherlock.app.SherlockFragmentActivity;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.NavUtils;
import com.actionbarsherlock.view.*;
public class MainActivity extends SherlockFragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//private GoogleMap map;
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getSupportMenuInflater().inflate(R.menu.main, menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
return true;
case R.id.action_search:
final int RESULT=1;
startActivityForResult(new Intent(MainActivity.this, SearchForm.class), RESULT);
return true;
}
return super.onOptionsItemSelected(item);
}
}

Well, I figured it out; i didnt have to use the android:permission atribute under the activities in the manifest. After deleting that the app works just fine.
You can try this code.
public class MainActivity extends FragmentActivity {
// for google map
private GoogleMap mMap;
SupportMapFragment mapFragment;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mMap = mapFragment.getMap();
mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
mMap.getUiSettings().setCompassEnabled(true);
mMap.getUiSettings().setZoomControlsEnabled(true);
}
If you getting any problem then let me know.
Current Status: PROBLEM HAS NOT SOLVED YET- NEED HELP..
Im now developing a map app by using the new google maps Android v2..Before I apply it into my real app..I did a testing..and tried to make it works..I followed the documentation by Google Developers
But seems there are some part I missed, But couldn't find them.. Can u identify them for me? I willl give u my source code below...to let u see them clearly..

For your information,
I already generate a new api key in my google account by copy my
SHAI num from eclipse..
I did this steps Android Tools> rightclick> Export Signed
Application Packages (to make them link each other, I create new
keystore) My QUESTION IS: should I implement this (no 2)??
Please let me know if u found any mistakes I have made.. thank you
You made a mistake you are trying to access android.R.id.content where in your my activity_main.xml file Mapfragment id is android:id="#+id/map"
So, try this way.
Put this Code in your onCreate(..) method
SupportMapFragment fragment = new SupportMapFragment();
getSupportFragmentManager().beginTransaction()
.add(R.id.map, fragment).commit();
instead of this.
SupportMapFragment fragment = new SupportMapFragment();
getSupportFragmentManager().beginTransaction()
.add(android.R.id.content, fragment).commit();
Instead of using the commit() use the .getMap(); method to get and load the map.
GoogleMap mMap;
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap();
