Answer 1

Some hints to get you going bro :)

StringBuffer buf = new StringBuffer();
buf.append("VERSION.RELEASE {"+Build.VERSION.RELEASE+"}");
buf.append("\nVERSION.INCREMENTAL {"+Build.VERSION.INCREMENTAL+"}");
buf.append("\nVERSION.SDK {"+Build.VERSION.SDK+"}");
buf.append("\nBOARD {"+Build.BOARD+"}");
buf.append("\nBRAND {"+Build.BRAND+"}");
buf.append("\nDEVICE {"+Build.DEVICE+"}");
buf.append("\nFINGERPRINT {"+Build.FINGERPRINT+"}");
buf.append("\nHOST {"+Build.HOST+"}");
buf.append("\nID {"+Build.ID+"}");
Log.d("build",buf); 

Answer 2

Build.VERSION.RELEASE;

That will give you the actual numbers of your version; aka 2.3.3 or 2.2. The problem with using Build.VERSION.SDK_INT is if you have a rooted phone or custom rom, you could have a none standard OS (aka my android is running 2.3.5) and that will return a null when using Build.VERSION.SDK_INT so Build.VERSION.RELEASE will work no matter what!

To use it, you could just do this;

String androidOS = Build.VERSION.RELEASE;
