I Downloaded google play service and add it to my workspace, but When I try to start application in my phone, it crashes:
05-04 20:11:24.441: E/AndroidRuntime(11190): FATAL EXCEPTION: main
05-04 20:11:24.441: E/AndroidRuntime(11190):
java.lang.RuntimeException: Unable to start activity
ComponentInfo{com.dude.uniplaces/com.dude.uniplaces.Index}:
android.view.InflateException: Binary XML file line #19: Error
inflating class fragment
EDIT:
I modified my index.xml as you saw me, then I added (think) in right way google libs, but i still take crash!
Solution:
I solved adding import android.support.v4.app.FragmentActivity;
and chancing extends Activity with FragmentActivity
Right click on the project and select Android Tools -> Add Support Library ...
and change this
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.MapFragment"/>
to this
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
and just to confirm that you have included the google play services correctly right click on project and select Properties. In left tab select Android. In the botton of the right pane you shoud see a frame with label library. If google play is added correctly it will appear as green check mark. Also make sure that the google play project is open in the workspace.
It look like you have some kind of problem with the way you are referencing the google-play-services library. take a look at the first three step of this blog post I wrote on Google Maps API V2 to get an idea of how to do it correctly:
Google Maps API V2
Your min sdk in 8
Note : If you wish to run the app on api 11 and lower You will need to add support library as well.
http://developer.android.com/tools/extras/support-library.html
Use this
android:name="com.google.android.gms.maps.SupportMapFragment"
Also make sure you have followed all the steps from the below link
https://developers.google.com/maps/documentation/android/start
Edit
https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/MapFragment
MapFragment for api 12 and higher support fragment for api 11 and lower
Also make sure you map project references google play services library project.
Refer your google play services in your map project
To check if its a library project. right click on your project goto properties. choose android. check if Is Library is ticked.
To refer the library project in your map project.
right click on your project goto properties. choose android. Click add, browse the library project click add and ok. Notice the green tick below.
For more information check the below link
https://developer.android.com/tools/projects/projects-eclipse.html.
You also need to add Support library since you are using SupportFragment. Check the below link
https://developer.android.com/tools/extras/support-library.html

I have check all settings, but it can't load the map with fragment but a zoom widget. It have no gridding. I have check the key but don't think it has any problem.

Make sure that you have activated android map v2 api on google console.
you have created proper android key by entering correct SHA1 and package name on google console.
try to run it on physical device.
Make sure you have "Google Repository" installed from the SDK manager. They never mention this in the instructions but this must be installed alongside the Google Play Services SDK for everything to function.
Because I'm in China, it's not convenient to access Google server. Therefore I used a proxy to make the network can access the Google and then everything goes well. Thank all you guys for responding and special thank to #Yazan who gave me a prompt.
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.

Add library to your AndroidManifest File:
<uses-library
android:name="com.google.android.maps"
android:required="true" />
Just check this:
package com.example.mymap;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.support.v4.app.FragmentActivity;
public class MainActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager myFM = .getSupportFragmentManager();
SupportMapFragment myMAPF = (SupportMapFragment) myFM
.findFragmentById(R.id.fragment1);
MAP = myMAPF.getMap();
MAP.setMyLocationEnabled(true);
MAP.setMapType(GoogleMap.MAP_TYPE_HYBRID);
MAP.setOnMapClickListener(new OnMapClickListener() {
#Override
public void onMapClick(LatLng point) {
// TODO Auto-generated method stub
MAP.addMarker(new MarkerOptions().position(point).title(
point.toString()));
Log.e("lat", "" + point);
}
});
}
}
Your xml file will be:
<fragment
android:id="#+id/fragment1"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_below="#+id/fragment1"
android:layout_centerHorizontal="true"
class="com.google.android.gms.maps.SupportMapFragment" />
And finally add libray in manifest file:
<uses-library
android:name="com.google.android.maps"
android:required="true" />
You should use SupportFragment Your min sdk is 8.
<fragment
class="com.google.android.gms.maps.SupportMapFragment"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Your activity must extend FragmentActivity
Import
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.SupportMapFragment;
Edit:
From your comments you say there is a error #
import com.google.android.gms.maps.SupportMapFragment;
So i guess you have not referenced google play services library project properly.
Download the Google Play services. Goto Windows. Goto Android Sdk Manager. Choose Google play services under extras.
Copy the google-play services_lib library project to your workspace. The library project can be found under the following path.
<android-sdk-folder>/extras/google/google_play_services/libproject/google-play-services_lib library project .
Import the library project to your eclipse
Click File > Import, select Android > Existing Android Code into Workspace, and browse the workspace import the library project. You can check if it is library project. Right click on the library project. Goto properties. Click Android on the left panel. You will see Is Library checked.
Try this.
In your xml file
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"/>
In the java file
public class MapExampleActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_map_example);
//setUpMap
}
i am showing a map in activity ... but when i run app on device it does not show any thing , it show just white screen and zoom in zoom out options... MAP key is right .. thanks ..

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.
google map is displying perfectly and googleplayservices are also present,
but my location button on top right corner is not working in google maps api v2 my wifi and gps both are on.Kindly help.

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.
