Android 4.0+平板电脑关键字？

Question

I heard that there is a keyword or method that Android developers can use to determine whether Android 4.0+ is running on a tablet (without having to do any kludgy screen size comparisons). I can't find it.

So, is this true? If so, what is it?

Edit: I see that people are giving me answers that are not what I'm looking for. I already know how to determine whether a device is a tablet or phone using the kludgy screen size method and using the OS method. I'm looking for a method that has been available starting with API level 14 that will tell me the same information -- hopefully. I can't find it, so I'm wondering whether it even exists.

Answer 1

Tablet basically just means a big(er) screen, so it comes down to that. There's an easy way of seeing if it's a tablet sized screen or not:

if ( getResources().getConfiguration().isLayoutSizeAtLeast( Configuration.SCREENLAYOUT_SIZE_XLARGE ) )
{
    //Is a tablet.
}

You could change Configuration.SCREENLAYOUT_SIZE_XLARGE to Configuration.SCREENLAYOUT_SIZE_LARGE if you want to catch smaller ones too.

Answer 2

As described in the android documentation, the SDK level (integer) the phone is running is available in:

android.os.Build.VERSION.SDK_INT;

The enum corresponding to this int is in the android.os.Build.VERSION_CODES class.

Code example:

int currentapiVersion = android.os.Build.VERSION.SDK_INT;
if (currentapiVersion >= android.os.Build.VERSION_CODES.FROYO){
    // Do something for froyo and above versions
} else{
    // do something for phones running an SDK before froyo
}

Edit: This SDK_INT is available since Donut (android 1.6 / API4) so make sure your application is not retro-compatible with Cupcake (android 1.5 / API3) when you use it or your application will crash (thanks to Programmer Bruce for the precision).

Answer 3

Android 4+ has the configuration object . You can use the "isLayoutSizeAtLeast(int size)" method to do your check. It's less kludgy than some other examples I've seen around.
