Android app Ant pack

1. preparatory work

(1) First install the ant tool .

(2) Generate KeyStore

In the bin directory of the JDK

Input

Enter by action and remember the password.

(3) configuration keystore, this is for signature.

Copy the resulting Andorid.keystore into the project's directory and build the ant.properties file

Key.alias name is consistent with keystore file name, password is the password you set before, two I made the same.

2. Start

(1) Generate compiled files build.xml and local.properties

First view the list of available target

And then enter

Android Update Project--name scaleimage--target android-15--path.

Yes (note: the specificTargetshould be based on the project'sTargetdecision, or there will be an error)

When there is an externally imported Jar Library, it will be automatically written, but when there is a dependent library , it is necessary to first set up the above two files in a dependent library , I encountered a similar problem , prompting you to use --subprojects

To the library directory, mine is

Input

Android update lib-project-p./

Then update to the original directory

Android Update Project--name scaleimage--target 12-p./--subprojects

Here target is optional, I have updated target at the same time

At this point, all work is done and you can view the root directory

(2) Packaging

Go back to Eclipse, update the project, add buildfiles in Ant

Debug is a default only one-year period of the signature,release is the previous set of the signing deadline, click release to complete the package, If you're having trouble , clean it up and try again .

Generated an apk package with a signature
