view full story

http://stackoverflow.com – i'm use to linux environment but at the moment i have to develop an android app under a windows environment. So i need to run the "android" command ( android.bat ) in the windows prompt ( located in $ANDROID_HOME/tools/android ) in order to add ant script and do other stuffs. the thing is that this launches me the Android SDK Manager, instead of giving me command line answer like : "project updated"... So my question is : How do i run the android command under Windows ?? to run things such as : android update project --path Maybe i'm not running the right bat file ? I did many search ove (HowTos)
