integrate google plus android error

https://developers.google.com/+/mobile/android/getting-started This is my code:

public class MainActivity extends Activity implements ConnectionCallbacks, OnConnectionFailedListener{
 private static final int RC_SIGN_IN = 0;

  /* Client used to interact with Google APIs. */
  private GoogleApiClient mGoogleApiClient;
  /* A flag indicating that a PendingIntent is in progress and prevents
   * us from starting further intents.
   */
  private boolean mIntentInProgress;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mGoogleApiClient = new GoogleApiClient.Builder(this).addConnectionCallbacks(this).addOnConnectionFailedListener(this).addApi(Plus.API, null).addScope(Plus.SCOPE_PLUS_LOGIN).build();
    setContentView(R.layout.activity_main);
}
protected void onStart() {
    super.onStart();
    mGoogleApiClient.connect();
  }

  protected void onStop() {
    super.onStop();
    if (mGoogleApiClient.isConnected()) {
      mGoogleApiClient.disconnect();
    }
  }
  public void onConnectionFailed(ConnectionResult result) {
      if (!mIntentInProgress && result.hasResolution()) {
        try {
          mIntentInProgress = true;
          result.startResolutionForResult(this, RC_SIGN_IN);
        } catch (SendIntentException e) {
          // The intent was canceled before it was sent.  Return to the default
          // state and attempt to connect to get an updated ConnectionResult.
          mIntentInProgress = false;
          mGoogleApiClient.connect();
        }
      }
    }

    public void onConnected(Bundle connectionHint) {
      // We've resolved any connection errors.  mGoogleApiClient can be used to
      // access Google APIs on behalf of the user.
    }
    protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
          if (requestCode == RC_SIGN_IN) {
            mIntentInProgress = false;

            if (!mGoogleApiClient.isConnecting()) {
              mGoogleApiClient.connect();
            }
          }
        }
    @Override
    public void onConnectionSuspended(int arg0) {
        mGoogleApiClient.connect();
    }
}.

At first, i see the line mIntentInProgress == false; and receive error:
Syntax error on token "==", invalid AssignmentOperator so i changed to mIntentInProgress = false; but then, when i run, it crashes.

Instead of

.addApi(Plus.API, null)

try this:

.addApi(Plus.API)

That worked for me.

As stated in the error - you cannot use a null PlusOptions - connecting to the Plus API should look like:

mGoogleApiClient = new GoogleApiClient.Builder(this)
    .addConnectionCallbacks(this).addOnConnectionFailedListener(this)
    .addApi(Plus.API, new Plus.PlusOptions.Builder().build()) // note the options
    .addScope(Plus.SCOPE_PLUS_LOGIN).build();
