How to get the Android OS installed version programmatically

There are always certain new features added to later/newer versions of android SDK that are not supported by older devices. For such scenarios, one needs to know the version of Android OS running on a device so as to customize the code functionality accordingly. Or, you are trying to restrict your application to run of older devices or devices that are running on an older Android OS.

✋️ android.os.Build.VERSION.SDK_INT will provide you the current Android OS details

The simplest of ways of doing this (for testing) is by printing the below code snippet in your logs

int currentVer = android.os.Build.VERSION.SDK_INT;
Log.i("Activity", currentVer);

if( currentVer == FROYO ) {
         //Some code
      }
    else if ( currentVer == GINGERBREAD ) {
         //Some code
    }
    else {
         //Some code
   }
