Adding a google sign in button - sign in problems

Question

I am trying to put google sign in button in my android app. I have take reference from https://developers.google.com/+/mobile/android/sign-in and it showing me continuous progress bar and doesn't log into my account. I have already added my id on emulator. I am attaching the image of it. And here is my code.

public class MyActivity extends Activity implements GooglePlayServicesClient.ConnectionCallbacks, GooglePlayServicesClient.OnConnectionFailedListener, View.OnClickListener {

    private static final String TAG = "ExampleActivity";
    private static final int REQUEST_CODE_RESOLVE_ERR = 9000;

    private ProgressDialog mConnectionProgressDialog;
    private PlusClient mPlusClient;
    private ConnectionResult mConnectionResult;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mPlusClient = new PlusClient.Builder(this, this, this)
                .setActions("http://schemas.google.com/AddActivity", "http://schemas.google.com/BuyActivity")
                .build();
        findViewById(R.id.sign_in_button).setOnClickListener(this);
        mConnectionProgressDialog = new ProgressDialog(this);
        mConnectionProgressDialog.setMessage("Signing in...");
    }


    @Override
    public void onConnected(Bundle bundle) {
        // We've resolved any connection errors.
        mConnectionProgressDialog.dismiss();
        Toast.makeText(this, " User is connected.", Toast.LENGTH_LONG).show();
    }

    @Override
    public void onDisconnected() {
        Log.d(TAG, "disconnected");
    }

    @Override
    public void onConnectionFailed(ConnectionResult connectionResult) {
        if (mConnectionProgressDialog.isShowing()) {
            // The user clicked the sign-in button already. Start to resolve
            // connection errors. Wait until onConnected() to dismiss the
            // connection dialog.
            if (connectionResult.hasResolution()) {
                try {
                    connectionResult.startResolutionForResult(this, REQUEST_CODE_RESOLVE_ERR);
                } catch (IntentSender.SendIntentException e) {
                    mPlusClient.connect();
                }
            }
        }

        // Save the intent so that we can start an activity when the user clicks
        // the sign-in button.
        mConnectionResult = connectionResult;
    }

    @Override
    public void onClick(View view) {
        if (view.getId() == R.id.sign_in_button && !mPlusClient.isConnected()) {
            if (mConnectionResult == null) {
                mConnectionProgressDialog.show();
            } else {
                try {
                    mConnectionResult.startResolutionForResult(this, REQUEST_CODE_RESOLVE_ERR);
                } catch (IntentSender.SendIntentException e) {
                    // Try connecting again.
                    mConnectionResult = null;
                    mPlusClient.connect();
                }
            }
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
        if (requestCode == REQUEST_CODE_RESOLVE_ERR && responseCode == RESULT_OK) {
            mConnectionResult = null;
            mPlusClient.connect();
        }
    }
}

            </intent-filter>

        </activity>
    </application>
</manifest>]

Even after turn on google api in console it shows me error and google+ app is already installed on my device. i am posting both images.

Answer 1

mPlusClient.connect(); is not being called anywhere. you are just showing the progress bar in the click event rather than trying to connect.

link

From Plusclient doc

You should instantiate this object in your Activity's onCreate(Bundle) method and then call connect() in onStart() and disconnect() in onStop(), regardless of the state.

Try adding mPlusClient in onStart or in the button click.
