gradle打包android （實現外部導入簽名文件、多渠道打包、導入ant腳本）
近期一直在做android自己主動打包，之前已經完畢了用純命令行的形式打包、原生態ant腳本打包。和基於android的SDK的打包。而且實現了多渠道打包，後來同事推薦了gradle,網上的資料說gradle各種好，自己也感興趣是實現一下。事實上一般來說因為android對eclipse的支持減弱，大部分的人都是用gradle與android studio融合，這樣面的樣例也會比較多，但筆者所在的項目還是在eclipse的比較多。因為開發者在移植過程中發現報錯比較多所以一直沒有全然移植（好吧，事實上早晚會移植），所以筆者是用eclipse的IDE做的實驗，以下先貼幾個基礎知識
首先是新建一個android項目，然後用自帶的IDE生成gradle文件，詳細參考http://blog.csdn.net/x605940745/article/details/41242687，有興趣的同誌們能夠採取純手寫的方式，這樣的方式能夠不依賴IDE，所以會比較好
這個是原始的build.gradle
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath ‘com.android.tools.build:gradle:0.8.+‘
}
}
apply plugin: ‘android‘
dependencies {
compile fileTree(dir: ‘libs‘, include: ‘*.jar‘)
}
android {
compileSdkVersion 19
buildToolsVersion "19.0.3"
sourceSets {
main {
manifest.srcFile ‘AndroidManifest.xml‘
java.srcDirs = [‘src‘]
resources.srcDirs = [‘src‘]
aidl.srcDirs = [‘src‘]
renderscript.srcDirs = [‘src‘]
res.srcDirs = [‘res‘]
assets.srcDirs = [‘assets‘]
}
// Move the tests to tests/java, tests/res, etc...
instrumentTest.setRoot(‘tests‘)
// Move the build types to build-types/<type>
// For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
// This moves them out of them default location under src/<type>/... which would
// conflict with src/ being used by the main source set.
// Adding new build types or product flavors should be accompanied
// by a similar customization.
debug.setRoot(‘build-types/debug‘)
release.setRoot(‘build-types/release‘)
}
}
以下我先附上自己的build.gradle
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath ‘com.android.tools.build:gradle:0.12.+‘
}
}
apply plugin: ‘android‘
ant.importBuild ‘build.xml‘ //這裏導入了ant的腳本
dependencies {
compile fileTree(dir: ‘libs‘, include: ‘*.jar‘)
}
android {
compileSdkVersion 19
buildToolsVersion "20.0.0"
signingConfigs { //簽名，這裏的文件名稱和password是錯的，後面還會有從外部導入的語句
myConfig {
//絕對路徑和相對路徑都能夠
storeFile file("E:\\keystore\\mydemo.keystore") //簽名文件
storePassword "276021750" //password
keyAlias "mydemo.keystore"
keyPassword "111"
}
}
buildTypes{
release { //這裏就是用來生成apk的步驟。詳細看備註
//1.加入簽名
signingConfig signingConfigs.myConfig
//2.runProguard 運行混淆代碼
runProguard true
//混淆規則文件
proguardFiles getDefaultProguardFile(‘proguard-android.txt‘), ‘proguard-project.txt‘
}
}
productFlavors { //這裏是多渠道的地方，AndroidManifest.xml文件中面要有標示，以下會貼文件
yingyongbao {
manifestPlaceholders = [ CHANNEL_NAME:"YINGYONGBAO"]
}
umeng {
manifestPlaceholders = [ CHANNEL_NAME:"UMENG" ]
}
wandoujia {
manifestPlaceholders = [ CHANNEL_NAME:"WANDOUJIA" ]
}
}
allprojects { //在這裏是外部導入文件，然後更改本身文件的屬性。這裏僅僅改了簽名，還能夠改其它的
afterEvaluate { project ->
def propsFile = rootProject.file(‘E:\\keystore\\keystore.properties‘)
def configName = ‘myConfig‘
if (propsFile.exists() && android.signingConfigs.hasProperty(configName)) {
def props = new Properties()
props.load(new FileInputStream(propsFile))
android.signingConfigs[configName].storeFile = file(props[‘storeFile‘])
android.signingConfigs[configName].storePassword = props[‘storePassword‘]
android.signingConfigs[configName].keyAlias = props[‘keyAlias‘]
android.signingConfigs[configName].keyPassword = props[‘keyPassword‘]
}
}
}
sourceSets {
main {
manifest.srcFile ‘AndroidManifest.xml‘
java.srcDirs = [‘src‘]
resources.srcDirs = [‘src‘]
aidl.srcDirs = [‘src‘]
renderscript.srcDirs = [‘src‘]
res.srcDirs = [‘res‘]
assets.srcDirs = [‘assets‘]
}
// Move the tests to tests/java, tests/res, etc...
instrumentTest.setRoot(‘tests‘)
// Move the build types to build-types/<type>
// For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
// This moves them out of them default location under src/<type>/... which would
// conflict with src/ being used by the main source set.
// Adding new build types or product flavors should be accompanied
// by a similar customization.
debug.setRoot(‘build-types/debug‘)
release.setRoot(‘build-types/release‘)
}
} <meta-data
android:name="UMENG_CHANNEL"
android:value="${CHANNEL_NAME}" />build.xml加入了一個target，用cmd命令寫gradle deploy就能夠運行裏面的內容了 <target name="deploy">
<!-- <replaceregexp flags="g" byline="true">
<regexp pattern="public static final Host host = Host.Development;" />
substitution expression 中是替換的值。替換的值都定義在相相應的配置文件裏
<substitution expression="public static final Host host = Host.Test;" />
fileset 屬性中的 dir 用來指定被替換文件所在的文件夾
includes 用來指定要替換哪個文件。
<fileset dir="./src/net/xtion/crm/base" includes="CrmAppContext.java" />
</replaceregexp> -->
<replace encoding="utf-8" dir="./src/com/example/learn723">
<include name="MainActivity.java" />
<replacefilter token="public static final String host = "Host.Test";" value="public static final String host = "Host.abc";" />
</replace>
</target>
另一個簽名文件storeFile=E:\\keystore\\mydemo.keystore storePassword=276021750 keyPassword=276021750 keyAlias=mydemo.keystore

這種優點我們能夠看到。用ant專職改文件的信息。這裏專門做多渠道的打包，能夠分開，事實上要做到全自己主動還有兩步，一個是從svn自己主動獲取。這個網上有非常多的版本號能夠學習，還有一個是用腳本改動build.gradle文件，動態變換簽名（事實上也能夠做批量改動）和動態添加這些功能的代碼，能夠用shell，能夠用python，各位用須要能夠試一下
