Question: I would like to do the following in my app:

* Portrait mode only for the phone
* Portrait mode and landscape mode for tablets.

I know i can easily change the orientation in the manifest file but that will affect the entire application. 

I have also thought of creating separate activities, to handle the different versions but i don't know how to detect the type of device using the application.

Does anyone know how to tackle this?

Answer: 
In activity's onCreate method check whether app is running on phone or on tablet. If app is running on phone set activity screen orientation to portrait only.

Add these files to your res folder.

**res/values/vars.xml:**

```
<?xml version="1.0" encoding="utf-8"?><resources><bool name="is_tablet">false</bool></resources>

```

**res/values-sw600dp/vars.xml:**

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

```

In onCreate method off all your activites add this code:

```
    if (!getResources().getBoolean(R.bool.is_tablet)) {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    }

```
i suppose you can do small trick for it, try use `Configuration.screenLayout` :

```
  switch (this.getResources().getConfiguration().screenLayout) {
        case Configuration.SCREENLAYOUT_SIZE_SMALL:
                return "small";
            case Configuration.SCREENLAYOUT_SIZE_NORMAL:
                return "normal";
            case Configuration.SCREENLAYOUT_SIZE_LARGE:
                return "large";
            case 4: // screen xlarge 
                return "xlarge";
            default:
                return "undefined";
            }
        }

```

thanks
