Runtime errors while Launching the Map

Here's my onCreate() Method..The two commented lines were used previously to launch the map and it worked fine.Later I found out Google doen't use LocationClient anymore and they use GoogleAPIClient instead.So I changed it.

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button send = (Button) findViewById(R.id.button2);

        if(initMap())
        {  
            //mLocationClient = new LocationClient(this,this,this);
            //mLocationClient.connect();
            mGoogleApiClient =new GoogleApiClient.Builder(MainActivity.this)
            .addApi(LocationServices.API)
            .addConnectionCallbacks(MainActivity.this)
            .addOnConnectionFailedListener(MainActivity.this)
            .build();
        }
        else
        {
            Toast.makeText(this,"Map Not Available!",Toast.LENGTH_SHORT).show();
        }
    }

This is initMap Method

private boolean initMap(){
        if(mMap==null)
        {
            //making Reference to Map Object
            SupportMapFragment mapFrag = (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map); 
            mMap=mapFrag.getMap();
        }
        return(mMap!=null);
    }

This is the logcat report.

Here is the problem your activity is there alright, but Eclipse didn't include the support package in the APK ... If you look above your error in stacktrace you will notice the root of your problem:

 Didn't find class "com.google.android.gms.R$styleable" on path: DexPathList[[zip file "/data/app/com.example.mapsproject-2/base.apk"],nativeLibraryDirectories=[/vendor/lib, /system/lib]]

So you can unpack the apk, undex it and you will see the compatibility package classes were not included.

To fix this

Using Eclipse
