I'm following this https://developers.google.com/maps/documentation/android/start#installing_the_google_maps_android_v2_api to learn to use Google Map API.
This is my manifest:

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
回答1:
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.
回答2:
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
回答3:
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
