loading activity dynamically shows up a blank screen first

HI I am loading a dynamic activity based on if the user is logged in or not. I search through internet and got a solution which asks to create a blank activity, check the condition in oncreate, start new activity based on the condition and finish the blank activity. However, this shows me a blank white screen for 1-2 seconds. How do I avoid it?

(I have deleted the default layout when the blank activity is created.)

Here is my code:

public class BlankActivity extends Activity {
    public  SharedPreferences mStoredValues;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Intent loadIntent;
        mStoredValues = getSharedPreferences(Constants.STORED_VALUES, 0);
        if (mStoredValues.contains(Constants.ACCESS_TOKEN)) {
            loadIntent = new Intent(BlankActivity.this, HomeScreen.class);
        }   
        else {
            loadIntent = new Intent(BlankActivity.this, Login.class);
        }
        startActivity(loadIntent);

        finish();
    }
}

Here are the activity details in Manifest file.

        <activity
            android:name="com.citrus.citruspay.BlankActivity"
            android:launchMode="singleInstance"
            android:noHistory="true" 
            >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

You should use Fragments to cover this situation. You can choose which fragment you add in your activity dynamically. Try something like this:

public class FirstActivity extends FragmentActivity {
super.onCreate(savedInstanceState);
    setContentView(R.layout.main_layout);
    mStoredValues = getSharedPreferences(Constants.STORED_VALUES, 0);
    Fragment fragment;
    if (mStoredValues.contains(Constants.ACCESS_TOKEN)) {
        fragment = new HomeScreenFragment();
    }   
    else {
        fragment = new LoginFragment();
    }
    getFragmentManager().beginTransaction().add(R.id.container_id,fragment).commit();
}

Add android:theme="@android:style/Theme.Translucent.NoTitleBar" to your first activity tag in the manifest and see.

 <activity  android:theme="@android:style/Theme.Translucent.NoTitleBar"
            android:name="com.citrus.citruspay.BlankActivity"
            android:launchMode="singleInstance"
            android:noHistory="true" 
            >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
