Androidがphoneかtabletかをチェックするには

SDKバージョンをみてHoneycombかどうか、画面サイズを見てタブレットかどうかでチェックをする。よく忘れてぐぐるのでここにメモ。

public static boolean isHoneycomb() {
    // Can use static final constants like HONEYCOMB, declared in later versions
    // of the OS since they are inlined at compile time. This is guaranteed behavior.
    return Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB;
}

public static boolean isTablet(Context context) {
    return (context.getResources().getConfiguration().screenLayout
            & Configuration.SCREENLAYOUT_SIZE_MASK)
            >= Configuration.SCREENLAYOUT_SIZE_LARGE;
}

public static boolean isHoneycombTablet(Context context) {
    return isHoneycomb() && isTablet(context);
}
