问题
I am using Ant to build my application.my app uses a library project.so first of all i had run the below command in commandline to generate the build.xml in my project.
"android update project --target 5 -p path_of_my_project -l path_of_my_library_project"
(my application's build target is 4.0).Above command generated a build.xml file in my project.Then i run "ant" command in command prompt.it has shown the result as BUILD SUCCESSFULL. but when i checked my project's bin folder there is no apk file is generated.what is the issue?I did not make any changes in build.xml file.do i need to add something to that to generate the build?please guide me.
