I have ten Android projects in one folder. For each project, I can use ant debug to build it. So it is no problem to write a simple script to compile all these proj
ant debug
You can define your keystore configure in your project.properties in your project folder. Just like this
key.store=/path/to/your/keystore key.alias=yourkeyalias key.store.password=yourkeystorepassword key.alias.password=yourkeyaliaspassword
key.store=/path/to/your/keystore
key.alias=yourkeyalias
key.store.password=yourkeystorepassword
key.alias.password=yourkeyaliaspassword
