Android Ant's simplest packaging signature and obfuscation method

With ant packaging, it's a bit of a hassle if the script is written step-by-step.

For Ant, let's look at it in detail:

Ant supports commands such as Ant debug,ant release, we need the signature to be confused, then we need ant release this command.

First of all: Ant environment, I will not say more, many blogs have introduced, including some environmental configuration

Then: After the ant environment is OK, we need a build.xml file, which is what ant compiles to find.

<?xml version="1.0" encoding="UTF-8"?>
<project
    name="EPAPP"
    default="helpme" >
    <property file="local.properties" />
    <property file="ant.properties" />
    <loadproperties srcFile="project.properties" />
    <!-- quick check on sdk.dir -->
    <fail
        message="sdk.dir is missing. Make sure to generate local.properties using 'android update project' or to inject it through an env var"
        unless="sdk.dir" />
    <import
        file="custom_rules.xml"
        optional="true" />
    <!-- import file="build_of_sdk.xml" / -->
    <import file="${sdk.dir}/tools/ant/build.xml" />
	
    <target
        name="cleand"
        depends="clean" >
		<delete file="./assets/config.properties"/> 
	</target>

    <target
        name="d"
        depends="cleand" >

        <property
            name="out.final.file"
            value="./dist/develop/ep.apk" />
			
		<mkdir dir="./dist/develop"/>
			
        <antcall target="release" />
    </target>

    <target name="helpme">
        <echo>Android Ant Build For EPAPP. Available targets:</echo>
        <echo>   helpme:    Displays this help.</echo>
        <echo>   d:         Builds for final.</echo>
        <echo>              Final release for production.</echo>
        <echo>Please feel free to ask help from wangle@easipass.com</echo>
        <echo>Sorry for this messed English show. :) </echo>
    </target>
</project>

This script corresponds to Ant's Build.xml is not a little bit, but pay attention to configure environment variables OH.

Where the <import file= "${sdk.dir}/tools/ant/build.xml"/> is the one that was imported into Ant's own build.xml, because the script was imported

<antcall target= "release"/> This sentence can be performed normally

And then: We add an ant-used configuration script: This script is executed by Ant Build.xml, and we don't care.

File name is Ant.properties

Proguard.config=proguard.cfg
key.store=./xxxxx.keystore
key.alias=xxxx
key.store.password=123456
key.alias.password=123456

Needless to say, you know what it is. Oh, open the confusion, import the signature. The first line is to open the confusion, the second line is the import signature, and the signature password

As for the signature, I will not say, with a signature

Key.store=./xxxxx.keystore this is to give the signature of the path, I was directly copy the signature to the engineering directory, you can configure your own OH.

Here, the shelves have been built. Oh, the next is according to their special needs, add some processing

Here's a little bit of a control to introduce confusion

Proguard.cfg This is a confusing script, because some of the three-party package and Android came with four components, and so on, we can not confuse them (the three-party package has been confused once, confusion will be problematic, and the four formed because they will be called by the Android system, confusion, the system can not find), otherwise there will be problems

The confusion about JSON should be noted in particular, referring to the previous blog http://blog.csdn.net/brightshadow11111/article/details/9469159

I posted my proguard.cfg script.
