Disabling the rotation on a tablet

My app has rotation enabled for mobiles but I don't want landscape mode in tablet.

I have tried 

<activity 
    android:screenOrientation="portrait" />

but this does't specify portrait mode for tablets only.

You can set it up from code but you can also have it in XML file only, but the trick is to use resource qualifiers and either have separate XML for what you call tablet or have separate style for tablets and apply that style to the activity.

I think you will need to do it programmatically, I don't think is any property for the manifest to set it up.

First step detect app installed in a tablet, something like this:

Java:

 public boolean isTablet(Context context) {
        boolean xlarge = ((context.getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_XLARGE);
        boolean large = ((context.getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) == Configuration.SCREENLAYOUT_SIZE_LARGE);
        return (xlarge || large);
    }

Kotlin

fun isTablet(context: Context): Boolean {
        val xlarge = context.resources.configuration.screenLayout and Configuration.SCREENLAYOUT_SIZE_MASK === Configuration.SCREENLAYOUT_SIZE_XLARGE
        val large =
            context.resources.configuration.screenLayout and Configuration.SCREENLAYOUT_SIZE_MASK === Configuration.SCREENLAYOUT_SIZE_LARGE
        return xlarge || large
    }

Kotlin extension:

    fun Context.isTablet(): Boolean {
        val xlarge = resources.configuration.screenLayout and Configuration.SCREENLAYOUT_SIZE_MASK === Configuration.SCREENLAYOUT_SIZE_XLARGE
        val large =
            resources.configuration.screenLayout and Configuration.SCREENLAYOUT_SIZE_MASK === Configuration.SCREENLAYOUT_SIZE_LARGE
        return xlarge || large
    }

Second step, change it in onCreate:

Java


if(isTablet(this)){
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}

Kotlin extension

  override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        if(isTablet()){
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        }
    }
