Use the API level. This is one of the very first thing the Android Developer's site teaches you in their training docs, if you haven't had a chance to read it yet I highly recommend it. There's a ton of good information in there.

if ( Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB ) {
    // Is Honeycomb or newer
}

Working fine Thanks Mr.Jon – Deepak Sep 23 '13 at 10:05
not worked for me as expected, for version R, it shows 'Base11 | Donut | Froyo | JellyBean' instead of R – user6159419 Oct 22 '20 at 18:48

You can get SDK version as integer by

int version=Build.VERSION.SDK_INT;

then you can compare it to some value. Like

if(version>=Build.VERSION_CODES.GINGERBREAD_MR1){
    do_something();
}
else{
    do_something_else();
}

You can get other version code by

Build.VERSION_CODES.*

Eclipse IDE will help you to find what you are looking for.

Edit: Fixed for the version ID you're looking for

This will basically take the first integer before the first dot. Make sure to do appropriate checks if the script is empty or if a dot even exists first.

String versionInt = deviceVersion.split("\\.")[0];

Why the downvote? I know that Android provides a native way of getting the version code, but since that solution was answered in a few answers already - I decided to provide a different perspective - of using native Java functionality. Maybe that's what the OP needed. Who said he needed to get the Android build version? – Dzhuneyt Sep 23 '13 at 19:58
Yes, thank you! :D – sanevys May 18 '21 at 08:57

You can use this:

android.os.Build.VERSION

to get the version, and then you can use it to implement your code..
