如何獲取Android版本號

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).
