Maps Android V2: java.lang.noclassdeffounderror: com.google.android.gms.R$styleable -

as many following error: java.lang.noclassdeffounderror: com.google.android.gms.r$styleable when trying implement maps android v2.

somehow must missing doing wrong, since it's not working. tried first copy google-play-services.lib lib folder, saw somewhere shouldn't this.

then tried import addon-google_apis-google-8 project, project gives error the import com.google cannot resolved.

i'm following vogella tutorial:

activity:

supportmapfragment fm = (supportmapfragment)   getsupportfragmentmanager().findfragmentbyid(r.id.map);         map = fm.getmap();           //map = ((mapfragment) getfragmentmanager().findfragmentbyid(r.id.map)).getmap();                 marker hamburg = map.addmarker(new markeroptions().position(hamburg)                     .title("hamburg"));                 marker kiel = map.addmarker(new markeroptions()                     .position(kiel)                     .title("kiel")                     .snippet("kiel cool")                     .icon(bitmapdescriptorfactory                         .fromresource(r.drawable.btn_logo)));                  // move camera instantly hamburg zoom of 15.                 map.movecamera(cameraupdatefactory.newlatlngzoom(hamburg, 15));                  // zoom in, animating camera.                 map.animatecamera(cameraupdatefactory.zoomto(10), 2000, null); 

manifest:

 <uses-sdk         android:minsdkversion="8"         android:targetsdkversion="17" />      <permission         android:name="com.testmap.test.permission.maps_receive"         android:protectionlevel="signature" />      <uses-permission android:name="com.testmap.test.permission.maps_receive" />     <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_fine_location"/>     <uses-permission android:name="android.permission.access_coarse_location"/>       <uses-permission android:name="android.permission.write_settings" />    uses-permission android:name="android.permission.internet" />    <uses-permission android:name="android.permission.access_network_state" />      <uses-feature         android:glesversion="0x00020000"         android:required="true" />                <meta-data             android:name="com.google.android.maps.v2.api_key"             android:value="a_real_api_key" />     </application> 

i retrieved a_real_api_key entering sha1 retrieved installing keytool plugin.. http://keytool.sourceforge.net/update fingerprint;com.testmap.test in google console.

and xml:

 <fragment         android:id="@+id/map"         android:layout_width="match_parent"         android:layout_height="match_parent"         class="com.google.android.gms.maps.supportmapfragment" /> 

i have feeling need import google-play-services library, can tell me step step how in eclipse, i've followed many answers, seem wrong every time.

yes, right. need import google_play_services_lib , add library project.

for this, need to:

1. download google play services android sdk manager

2. add project "importing existing android code base". go ~/<android_sdk>/extras/google/google_play_services/libproject , add workspace.

3. once project has been added workspace, right-click on it, go "properties" , "android" tab , mark library.

4. go application, , right-click go "properties" , go "android" tab , in library pane, click "add library". should show google_play_services project. add reference project.

5. another requirement right-click on project , go "android tools" option, , "add support library...".

this should maps running.

note: have add google play services "existing android code base" project , not jar.
