can an android application check the version of the phone

Question

I would like to write an application that uses live wallpapers for insatnce. this feature is supported only in version 7 and up. Is it posiible, that the application checks the version of the android phone and depending on that runs different code (e.g. uses live wallpaper or static background.)

Do you have a code example for that? Does that require special permissions?

Answer 1

Assuming you're requiring Android 1.6 or newer:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ECLAIR_MR1) {
    ...
}

Answer 2

Yes there is. Look at the Build class in Android. You can use it like so Build.VERSION.SDK_INT
