title: Android Studio "class" or "interface" expected
body: <p>i am following instruction provide in <a href="http://developer.android.com/training/location/retrieve-current.html" rel="noreferrer">http://developer.android.com/training/location/retrieve-current.html</a> to display user location. But leading to above stated compilation error.</p>
  
  <p>this is my code </p>
  
  <pre><code>public class MainActivity extends ActionBarActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
  
      private GoogleApiClient mGoogleApiClient;
      private Location mLastLocation;
      TextView tv1 = (TextView) findViewById(R.id.lat);
      TextView tv2 = (TextView) findViewById(R.id.lon);
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main); //ERROR '}' expected
  
          protected synchronized void buildGoogleApiClient() {
              mGoogleApiClient = new GoogleApiClient.Builder(this)
                      .addConnectionCallbacks(this)
                      .addOnConnectionFailedListener(this)
                      .addApi(LocationServices.API)
                      .build();
          }
      } // ERROR 'class' or 'interface' expected
  
  
      @Override
      public boolean onCreateOptionsMenu(Menu menu) {
          // Inflate the menu; this adds items to the action bar if it is present.
          getMenuInflater().inflate(R.menu.menu_main, menu);
          return true;
      }
  
      @Override
      public boolean onOptionsItemSelected(MenuItem item) {
          // Handle action bar item clicks here. The action bar will
          // automatically handle clicks on the Home/Up button, so long
          // as you specify a parent activity in AndroidManifest.xml.
          int id = item.getItemId();
  
          //noinspection SimplifiableIfStatement
          if (id == R.id.action_settings) {
              return true;
          }
  
          return super.onOptionsItemSelected(item);
      }
  
      @Override

          mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
                  mGoogleApiClient);
          if (mLastLocation != null) {
              tv1.setText(String.valueOf(mLastLocation.getLatitude()));
              tv1.setText(String.valueOf(mLastLocation.getLongitude()));
          }
      }
  
      @Override
      public void onConnectionSuspended(int i) {
  
      }
  
      @Override
      public void onConnectionFailed(ConnectionResult connectionResult) {
  
      }
  }
  </code></pre>
  
  <p>I go through the error and found its a syntax error. Can anyone tell me why it is failing in compilation?</p>
