Yup - this is by design the first time login occurs.
Steps:

• Kick off your MainActivity -> onResume is called.
• onResume is where we attempt to fetch a valid RestClient.
• This kicks off the login flow -> onPause is called and LoginActivity is launched.
• Login process completes and finish is called on LoginActivity.
• onResume is called on MainActivity -> This time there's a valid RestClient.

Thanks for quick response.

Steps to replicate the issue in my app.

I have created the SplashActivity (this is my main activity) launch on first time install the application.

SplashActivity -----> if user is not logged in then its calling a LoginActivitity(Salesforce standard login). This time the onResume method called for my SplashActivity.

LoginActivity----> enter the valid username and password then onResume (SplashActvity called twice) and i am checking RestClient client is null or not if not null then passing the HomeActivity.

After few second the HomeActivity called twice. Let me know where is the loop whole or what mistake i am doing.

SplashActivity calling this method.

 @override
 public void onResume(RestClient client) {
         this.client = client;

           if (client != null  && this.client.getAuthToken() != null) {
             // here i am calling my HomeActivity class
         }

  }

Let me know what mistake i am doing. Can you please guide me for this. Thanks for your response.

@vinod1988 Your onResume should look different. It should look more like this. We have base activities in the Mobile SDK such as SalesforceActivity for this purpose, to do all the heavy-lifting around account management for you. You can simply extend SalesforceActivity and onResume(RestClient client) will be called when a valid client is available post-authentication. This avoids the issues you're seeing around double calling. I'd recommend that path.

@bhariharan Thanks for the reply. I am giving you the my SplashActivity blue print code. Let me know where i am doing the wrong.

public class SplashActivity extends SalesforceActivity implements 
          LoaderManager.LoaderCallbacks<JSONArray> {

private RestClient client;

@Override
protected void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);

	// Setup view
	setContentView(R.layout.activity_splash_main);

}


@Override
public void onResume(RestClient client) {

    this.client = client;

	if (client != null  && this.client.getAuthToken() != null) {
                  // here i am calling my HomeActivity class
              }

    }
 }

This is my code that i have written inside the SplashActivity let me know where i am doing the wrong or not calling the proper method. @bhariharan Can u please guide me for this snippet code where i am doing the wrong. Thanks for your response.
