tip: check output , seek understand went wrong before posting here.
look error says:
unknown output extension: e:\year4\4thyearproject\projectcode\train
and 1 time 1 time again on dx command's output parameter:
c:\users\carl\appdata\local\android\android-studio\sdk\build-tools\19.1.0\dx.bat --dex --num-threads=4 --multi-dex --output e:\year4\4thyearproject\projectcode\train&gain\app\build\intermediates\dex\debug e:\year4\4thyearproject\projectcode\train&gain\app\build\intermediates\classes\debug e:\year4\4thyearproject\projectcode\train&gain\app\build\intermediates\dependency-cache\debug e:\year4\4thyearproject\projectcode\train&gain\app\build\intermediates\exploded-aar\com.google.android.gms\play-services\4.4.52\classes.jar c:\users\carl\appdata\local\android\android-studio\sdk\extras\android\m2repository\com\android\support\support-v4\19.1.0\support-v4-19.1.0.jar e:\year4\4thyearproject\projectcode\train&gain\app\build\intermediates\exploded-aar\com.android.support\appcompat-v7\19.1.0\classes.jar
can see [possible] error now? looks dx command terminates @ '&' sign. remove project name , seek again.
