I have been working on a radio app and along the way i decided to force only landscape to appear for tablets and portrait mode for phones.
Here is what i have done so far to achieve that.

First i put a bool resource in res.values to check for screen size.

```
 //  From my res/values/bool.xml(sw600 and 720)dp.

        <?xml version="1.0" encoding="utf-8"?>
        <resources>
            <bool name="landscape_only">true</bool>
        </resources>

// res/values/bool.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
    <bool name="portrait_only">true</bool>
</resources>

```

I then forced the requested screen orientations with code by checking the boolean in Main Activity.

```
     @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        // locking out landscape screen orientation for mobiles
        if(getResources().getBoolean(R.bool.portrait_only)){
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        }
        // locking out portait screen orientation for tablets
        if(getResources().getBoolean(R.bool.landscape_only)){
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

        }

        toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayShowTitleEnabled(false);

    }
}

```

So far, this worked pretty well. Now here's the issue i have.

When i implemented my code to lock out portrait mode for tablets my app started in portrait for a few seconds before switching to landscape. How do i make sure that it doesn't start off first in portrait? It should start off in landscape.
