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
}else{
// do something
}
Note：
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).
