[Android] My Tip; Android and ProGuard

Android and ProGuard
How to set ProGuard to ANT script for Android

STEP #1
Create a build.xml for ANT
c:/> ant update project --path c:/my_src
Create a build.property for keystore

STEP #2
EDIT build.xml

STEP #3
SETS ProGuard

STEP #4
BUILD

STEP #5
TEST, that's it!



//
// build.property
//
#application-package=com.test.testApp
#sdk-location=C:/android/android-sdk-windows/platforms/android-6

# KeyStore/Alias
key.store=__MY_KEYSTORE__.keystore
key.alias=__MY_KETSTORE_ALIAS__
key.store.password=__PASSWORD__
key.alias.password=__PASSWORD__

// --------------------------------
OPEN a rule xml file
<SDK_PATH>/platforms/<target_platform>/templates/android_rules.xml

COPY from in the below <project name="android_rules" default="debug">
to in the above </project>
then, PASTE this in the below ProGuard

// --------------------------------
// 4. Finds <target name="-dex" depends="compile">
// --------------------------------
then, adds ", optimize" beside "compile"

<!-- ProGuard -->
    <target name="-dex" depends="compile, optimize">
