Auto increment version code in Android app

Question

is there a way to auto-increment the version code each time you build an Android application in Eclipse?

I've done something similar but written it as a Desktop AIR app instead of some external C# (didn't feel installing another build system). Build this Flex/ActionScript app and change the path to your file, the build it as a standalone desktop app. It rewrites the 1.2.3 part of your file.

    

    
        
    

    
        ");
                var numberIndex:Number = startIndex + 15;
                var endIndex:Number = fileContents.indexOf("");

                if (startIndex == -1 || endIndex == -1)
                    return;

                var versionNumber:String = fileContents.substr(numberIndex, endIndex - numberIndex);
                var versionArr:Array = versionNumber.split(".");
                var newSub:Number = Number(versionArr[2]);
                newSub++;
                versionArr[2] = newSub.toString();
                versionNumber = versionArr.join(".");

                var newContents:String = fileContents.substr(0, startIndex) + "" + versionNumber + "" +
                                fileContents.substr(endIndex + 16);
                fileStream.close(); 


                fileStream = new FileStream();
                fileStream.open(myFile, FileMode.WRITE);
                fileStream.writeUTFBytes(newContents);
                fileStream.close(); 

                close();
            }
        ]]>
